  1. I was hoping to hear a little about what kind of alternators you guys use / have used and what your experience with them is. Like what size is it, for what vehicle, how many, what is it powering, what is it putting out? ...did it fail, is it nearly indestructible, did you have to customize your vehicle to make it fit (and how so?) Basically any information you provide would be really helpful. You can only find so much information from digging on the internet before you have to start asking questions. Anyway, I want to buy a new alternator for my Pontiac g6, but I'm really unsure of what to get. The biggest alt I can find for my vehicle is a 240 amp. Basically I'd like to be able to have a more than sufficient power supply if possible. I don't think there is any room to run a second alt under the hood.. Which would be nice. But I was thinking if there was a way for me to make a custom bracket to mount a bigger universal alternator.. that would probably be best? If anybody has personal experience with a g6 and alternators, please let me know! I would greatly appreciate any personal experiences, suggestions and feedback

  3. Parts of this log will be copied over from where I currently have it on CACO I just wanted to share it here since I'm a new member started working on it in early December it's a slow project. Well for a long time I'd been trying to sell my Grand Prix and just couldn't seem to get rid of it. Guy offered to trade me a Jeep and I've always wanted a jeep so despite the Jeep having 250K miles I took him up on it. The interior is super clean and the outside is in good shape as well. Rockers are a little rusty but that's a Michigan Jeep thing.The plan for the Jeep is for it to be a winter beater/audio ride. Trying to keep the salt off of my Duramax. As far as the audio goes planning a B Pillar 4th for 4 18's on roughly 8k. From my rough measurements today I will have 46 cubes gross to work with. Progress will be kind of slow as I'm currently laid off. The goal is to be finished by whenever the first show in Michigan is. Will be primarily competing in IASCA and ISPLL. I always wanted a cool build log name even though it's lame.Builds that I'll be pulling some inspiration from include, Galen Winesette's Jeep, Chris Russ' Jeep, and Don's TDH Jeep.Tenative Equipment List:Electrical2 Mechman 320's Externally RegulatedFull Throttle Group 31 for under the hoodJY Lithium (Leaning towards 80 AH)Welding Cable 2/0 (Lots of it)ILL Customz Battery Terminals Clarion CZ702 already have (unless I find a great deal on an 80 PRS)4 Cascade Omega Neo 18's (building motors like Robs, PSI recones likely)Amp must be under 8K class restrictions (Flatline B2A, M1S, AB 750.1)Not sure on mids probably Crescendo PWX's or McLaren4 Channels (Really thinking PPI 900.4's)Other:Welder (Really want a lincoln Power Mig 210 with the Tig torch)300 or so feet of steel 1x2 tubingAir Bags of some sort I'm sureBHE 4th order design or something similarVolt Meters Out with the old: In with the new: Like I said it's clean: Going to be a shame to gut it from the B-Pillar back: Steel sets:

  5. Sent the following to Mechman via their online form, but I figured I would post here to see if anyone else has any insight on this for me in the mean time while waiting for their response. "Hello, I purchased one of your alternators, via Sonic Electronix, for my 2008 Chevy Silverado. It has the 5.3L (VIN-J) and the alternator model is the 270A 8302270. I wired it with all 1/0 OFC cable, ensured the ground from the alternator to the battery runs through the Hall Effect sensor, used a 3/8” shorter belt (Gates) and replaced the tensioner for a new one (Gates). All works great except one thing, when the engine gets to about 3000-3500 RPM the voltage drops to battery voltage, then once back to idle the voltage comes back up. I'm not sure if this is by design or if there is some belt slippage at high RPM. If it is the latter, I cannot tell since it is a new install and I see no indication of belt dust yet. I wanted to get your input before I start going out buying anything. I eventually am going to order Gates Green Strip belts since I cannot get them locally, but I want to be sure of the length before I do. Right now, I have brand new Gate Micro-V belts installed since I can get those locally. The stock belt is 94" (K060935). Right now I have the 93-5/8" (K060930) installed, but the 93" (K060923) will fit, however with the 93" installed the tensioner is almost maxed, unsure if that is a factor or not. If you think I need a shorter belt, I will go out and purchase the 93" and if that solves my problem, I will be ordering the 93" Green Strip version (K060923HD). Thanks in advance and I hope to hear from you soon so I can resolve this." I should also mention I did try the 93" but never ran it with it due to the tensioner being almost maxed, so I returned it for the currently installed 93-5/8". I'm doing a new build to, so other than stock components, there are no aftermarket devices (amps, etc.) putting any additional load on the alternator other than a second battery.
  6. I've noticed that if I disconnect the negative terminal on my battery I still have power to the vehicle. I'll have to disconnect the positive to get it to completely turn off. I did an alternator swap on the Trailblazer and the big three so why do you you think this is happening? I've posted my set up on my build page as far as wiring. I can put a pic in this post if needed. Thanks!
  7. This is what my pulley is doing. I have a new belt on it, however it is the aftermarket correct length for a regular alternator. Does anyone know the correct model number in the Continental brand I can get? I'm sure this is not normal at idle and I need a shorter length. Just don't know how much... Belt I ordered. https://www.amazon.com/Continental-Elite-4060905-Poly-V-Serpentine/dp/B000C34KU6
  8. So i figure i should post some of my own car audio setuo here on SMD istead of just commenting on others stuff and posting "random pic's" Did alternator upgrade for the 2nd time (from a 170 G series mechman to 250 Elite) & wiring upgrade yesterday (for the 3rd time) i think it turned out ok. Not much to see in the cab but it does the job, My source unit, the istreamer i'm using is mounted to the backside of the side slider. I've got some running around to do this afternoon, will post some more pictures of the setup later.
  9. So last year I called up Mechman and they didn't have the specs to build an alternator for my 2014 Nissan Altima 2.5. I called recently and they will not be able to do my vehicle due to fitting issues Are there any alternatives out there or any other dealers that make one for my vehicle?
  10. so i have been looking around, maybe didnt look hard enough idk, but i cant seem to find out why with my setup im having a drop. 2004 Silverado Mechman 370 amp and voltage regulator with guage big 3 d3400 under hood d3100 in back Skar 2500 2 Fi Btl n2 at 1ohm So my voltage as far as i have read is ok to be set at 15v with these xs and i have had it this way for idk 2 years now and this issue has been this way whole time just asking the question now before i prep for the DC 10k to be put in, the issue is obviously voltage drop at idle its fine with alternator over the 1200 or 1500 rpm whatever it is but from reading other ppls setups to me seems like i should be able to run my setup full tilt without that much voltage drop. the voltage drop is enough to turn off my headunit so like below 13.5 idk my headunit doesnt like voltage too much lower than stock which is kinda good since it doesnt stay on like below 13 to really damage my stuff. So i know adding another d3100 id be set but for like 2700w 3 big batts and a 370 seems like alot, i checked my grounds they seem solid and fine its all 1/0 and hydraulic crimped so is there something wrong or does this setup seem like ya i should be dropping that much at idle because i dont want to have this problem when i add my 10k and have to have more batteries than i actually should need, and no i dont plan on running a 10k on just 2 batteries but i would like to know about how many d3100 i should need oh and system tuned with dd-1 and cc-1 headunit is pioneer DEH-x8500BS
  11. My alternator went to shit need a H.O. Alternator. Hit almost every one up and none want to make a Alternator For a 2010 Nissan Altima 2.5S. They have it for the 3.5 But its not an exact replacement already took a look at it. Does any one know a shop that would make it.
  12. Dad's mustang needs a little help. It has a junk battery in it, an outdated alternator, and the radio just quit working. Seems like a good time to put some audio equipment in it that we have laying around!!! The starting point is a 1991 5.0 Mustang LX Hatchback 5 speed. It has a 331 cubic inch stroker motor in it, 11:1 compression and AFR heads, so it should have no problem turning the 240 amp Billet alternator we will be putting on it !! System plans include: CDT 3 way components for front 6.5" mid drivers for rear fill SSA X-con 12 inch woofer in a ported box for bass Nano 5 channel amp for mids/highs Nano N3 for bass (About 2500 watts total) XS power D3400 battery MechMan 240 amp Billet hairpin alternator
  13. I received my mechman 370 alternator today and installed, however it's charging at 19v I'm sure this is not safe and was wondering if I did anything wrong. I have big 3 all 1/0 Memphis wire. Any help would be appreciated
  14. So I just got a SAZ-1200d and to go along with it (although possibly not needed) i was going to get a high output alternator to keep it going strong even at idle. Now i was going to go ahead and probably get the 240 amp alt from mechman. I know this is obviously more than needed for this amp but in a hobby drivin by upgrades i figure it will give me some room to expand. Now the question is, as of right now my big three is in 4 gauge sky high, is it okay to use a smaller amp fuse than what the alt is rated for (until i get a bigger amp later) since the 1200d only draws ~120 amps? Thanks in advance! Greg
  15. Here's my 1992 Camaro Z28. I've been building this for about 3 years now and here's how the car looks looks like today. I bought the car with only 62,000 miles on it, so it's very solid. Currently, my setup consists of the following: Alpine Head Unit Clarion EQS746 EQ Hertz HSK165XL's for front Hertz HSK165XL's for rear Fosgate T600-4 for Mids & Highs (2) Fi Audio Q12's Hi QTS Loaded Running Sealed Two Old School Fosgate Punch 200x2 wired to 2ohm Bridged Mechman 370A Alternator Single AGM Battery up front 19'' Wheels by AutoArt Hankook Tires New paint I'll be posting some pictures of the build that I've collected.
  16. Okay so here she is. This is a 2007 Ford F-150 in shadow grey and I've had it since I was 16. I dont have many pictures of before I did everything, but I wanted to get an overview type build log up and going. You can see what all equipment I have in my sig, but just in case that you can't here is all of it. Fi Q 15 High QTS option Rockford Fosgate T1500-1bdcp Rockford Fosgate T400-4ab Rockford Fosgate Punch 6.5 components Rockford Fosgate Punch 6x8 coaxials Pioneer AVH-P2300DVD Mechman 250 amp alternator XS Power D3400 Rockford Fosgate 1/0 wiring kit tons of SHCA wire That's all I can think about at the moment. Here is the headunit, and the SMD VM-1( one of my favorite things in the truck). Also what was the cigarette lighter is now a PAC LC-1. It's always funny to watch people's reactions when I'm turning what they think is the cigarette lighter and the bass gets louder. Here are the kill swiches for my system. Left to right is Mids&Highs, Sub, and then VM-1 Side shot of everything Here's a picture of the front doors with the 6.5 components in them. I'm not too particularly happy with how the doors turned out so I'll probably re-do them someday. Here's some pictures of the amps and the enclosure. The enclosure is 3.5 net cu. ft. sealed. Here is some under-the-hood shots. I know it's not particularly clean under the hood, but it's hard to keep it clean since I live in South Georgia and it's always either dry as hell or flooding rain. Probably some of the best money I've ever spent. Some more pictures of the outside, and some pictures next to my other baby. Well that's all I have for now. I'll post more pictures if I make any changes, but it's been this way for awhile so I probably wont make any changes soon. Also constructive criticism and help is always welcome, so feel free to comment and tell me if something doesn't look right or if there is a better way to do something. I won't get mad haha
  17. Just got cleaning the motor for the 2nd time this month. Helps me with install score for having clean engine bay. What do you thank. Mechman 320 supplying power. Sky High and KnuKoncept for wires.
  18. I'll add some pictures and details as I compile them. For now there's an entertaining video log. Work in progress, it's getting better every day. I'm very open to suggestions.
  19. Hey guys, i've completed my first sub/port forward build in the 2013 Camry and I'm pretty satisfied with it for now. I'm hoping I can get educated a little here for a future build. I would like to learn more about the design and characteristics of a 4th order. My trunk is fully sealed from the cabin right now. I have (2) DSS Ethos 12's on strapped Q2200's. Electrical Mechman 240, and a bank of 3 Autozone Platinum H6 AGM's (210ah combined). 2 runs of 1/0 front to back. No runs of 1/0 negative front to back, but am considering doing it because of voltage drop issue. Want to reinforce all my grounds... Can someone send me some decent links on how to learn the basics behind a good 4th order design? I understand its a ratio thing, and that's about all I ever get back in answers. Tune to around 45hz and let her go. I would like to get deeper in to the understanding of 4th orders so I can design an enclosure to house the 2 12's and get a little extra output from them. I guess what I don't understand is, how do I design the port to fire into the cabin and go about tuning it correctly? I think for what I'm looking for and going from the very limited knowledge I have, i would be looking for a 1:2 ratio, that way to gain a little more output and keep my frequency range a little more flat for music. This is a daily driver and not a burp vehicle, so please keep that in mind. Thanks in advance for any advise I can get... I don't mind doing the reading and research, so if someone can point me in the right direction, that will be great. Then hopefully, I can ask more knowledgeable questions in the future...
  20. New Install in Jeep Call it Furniture Grade Box. [/url]
  21. I'm sure you guys will like our giveaway for July! We partnered with Mechman and we are giving away an alternator of YOUR choice! Runner up gets a 0 gauge big 3 kit and 3rd gets a free Mechman shirt! Click the banner below to enter!
  22. Who has the cheapest alternator? Does cheap mean no warranties and really poor customer service? I've been told Iraggi is the cheapest with the worst customer service.
  23. Just came in after I chased the FedEx truck because he said he knock! No dogs barking like crazy. I called him a liar to his face and said he was lazy he did not want to carry a 90lb box. The whole box and sub weighs 150lb. Box in one of the stages of building. No nails or screws!!!!! Used #20 lemons to join together.
  24. 8 Inch RF Mids in Jeep Doors

    Installed 8 inch mids in Jeep front doors. Already had Pioneer Pro 8 mids in them. They sounded great. Made speaker pods out of 8 inch grey pvc pipe then made a 3/4 plywood jig 1/32 smaller then outside diameter of pipe, tis allows for plastic shrink due to heat from the rotor bit. Took 3 hours to do both panels plus epoxy and glass on the backs. Turned out great no flaws at all. If you want a opinion on the Pioneer Mids PM me. No bashing here. ]
  25. In the process of getting the above pictured XS Power D975 mounted in the trunk, but, as is sometimes the case, if you want to be near perfect, a brain fart, & I cannot proceed any further until I get a firm answer on the following ... Which is followed by the actual link to the Topic I started here on SMDF to illicit folks' responses somewhat faster, than just with an "Update" on my Build Log. Sooo, ... here goes: " Good afternoon, Folks ... I am sure this is oft-asked, ... but with these AGM batteries, XS' D975 offering in particular, when mounting in trunk, or any enclosed space for that matter, are vapors, fumes, etc., to be worried about? Or should I scheme up some sort of vent system of either a fan or filter, or both, ... or are AGM's different from Flooded BATTs in this regard, & obviously many others? (I would not be asking this if I have not read somewhere - maybe when I first purchased my D3400, that it was OK to mount these in many wacky positions ... just NOT upside-down ... & that AGM's nearly give off no toxic-ness. ... & if so, which way does any of the "offending" gasses escape? Up? Heavier than air so they lay low? As per my install, I am mounting said BATT terminal side up ... as I, & most would, describe as 'normal' orientation. Ready to mount BATT right now, but need to know if I should be fabbin' something first. Thank you ... " (http://www.stevemeadedesigns.com/board/topic/187377-xs-power-batt-d975-sealed-trunk-install-vapors-fumes-etc/ ) Thank to anyone who chimes in either there or here, or both! Be well ... PS: I am taking many photographs of this upgrade! Hopefully it will basically totally address my issues, & I can turn my attention to other stuff ... on other vehicles!
