I have a 2004 Pontiac Grand Prix. I have come across an alt for a 99-03 Pontiac Grand Prix. I see on your web site you have alts for 99-03, 05-08, and then the '04 is separate. Why is this? I know mine using a 4 pin and has the same mounting as both models.

We're excited to announce that we now carry yet another SMD partners products! This is the first time we have ever carried alternators! Mechman rocks and were glad to have them aboard! http://bit.ly/1p2TDKC

It is coming up on 3 years since I have had my 220A Alt installed on my 2005 xB and I just wanted to say a few things that I have encountered and experienced in this time. First off if you have a gen 1 xB and are going to install a large case conversion alt you will have to get a longer belt. What I have discovered is that by using the stock upper bracket that the belt over time stretches and eventually can not get enough tension on the belt as you max out the adjustability that the bracket will allow. All the rest of the hardware you will need comes with the alt so there are no worries there. The AVBM is awesome and it is a must to fine tune in your voltage output. I have had to slightly tweak the output for the different seasons because in the colder months the resistance was too low at startup and I was regularly charging at 15.1 or sometimes as much as 15.3V. My MS-8 processor does not like 15V+ and would make a crazy bad hissing sound at those levels. So the adjustability is awesome to have so that can be turned down a tad when needed. My output is always strong as long as I keep the engine RPM's up a little after it is fully hot in the hot summer heat of the south where I have lived since I have had this alt. I do notice that sometimes when slowing down and downshifting the RPM's will drop down 1.5-1.8V momentarily but it goes back to 14.4-14.6 where it usually is set at once I stop and maybe give the throttle a rev or two. All in all this alt is awesome and has met all of my expectations. I am working on getting a new upper bracket made so I can get a but more tension as to eliminate the cold start engine belt squeal. I hate hearing that in the early morning hours when I have to leave for work. Here is a comparison pic to the stock alt for reference:

Ordered last Friday and got it on Friday. Fast shipping looks like the one that is in Jeep already but it has a 160 amp big case already. Ready to install when it warms up! Beautiful work Mechman!!!!! Commander going to like this extra Juice! [sharedmedia=garage:vehicles:2438]

I am swapping my alt out for a mechman with a 1.75 inch pulley. I measured my stock pulley to be 2.5 inches. The belt for my car is approx. 84.5 inches. What size belt would i need. In order to swap my alternator out i need to remove the front passenger tire so using the "try multiple belt sizes until it fits" isn't the best approach for me Any help would be appreciated.

im new to this forum and im looking for some help for my install has anyone ever installed a mechman alt on a 2015 or newer yukon denali? i put 1 in already and it went bad(loud humming noise) in about a week. so i sent it out and mechman fixed it but the rep said i had it grounded wrong? he said you ground the newer style trucks different??? right now i have 1 yellow top optima battery up front luckily there was a empty spot for it and i still have the factory battery i ran 0 gauge from the positive on the factory battery to the yellow top then i grounded the optima battery to the frame then i ran 0 gauge from the alt positive to factory battery and grounded the alt to the factory battery with 0 gauge also what am i doing wrong ??? i couldnt understand what the rep was saying about the grounding issue! sorry if so confusing i tryd to explain it the best i can.... also would like to know how many batterys would someone run for my system? looking to use xs batterys in the back .should i take out the factory batterys and yellow top optima? if you think i should add somthing or somthing is wrong with my set up im all ears!! pics coming soon! i have..... 4 1000/1 slash v2 jl audio amps 2 600/6 jl audio amps 4 13.5 w7 jl audios 6 6*9 jl audios 4 6.5 jl audios 1 audio control LCQ-1 sound processor factory head unit

I have a couple of questions about a new build I'm putting together. I'm switching to my system to all lithium and will be eliminating my agm. I see everyone say that if you put lithium and agm together it will blow your alternator. Is this true? Also is it safe to start your car with lithium batteries? And is it recommended to purchase a bms for these deafbonce lithiums I got? https://alphardaudio.us/products/lithium-battery-lt-lfp-300p My system will be at around 9k watts powering 2 custom made 18 inch pierce audio 4k 12 magnet neo subs. My alternator is a 240 amp mechman, will 240 be enough to charge up my system I've heard that lithium is a lot of strain on alternators. If I'm driving my car just about every other day will I have to hook my batteries up to a lithium charger every other night or will they be fine to start my car every day and just wait a couple min for the alt to charge them? Sorry for all the questions but thank you for the help!!

Some background: I have always liked the F150 trucks and have owned several of them over the years. I had been planning out a system for those trucks for years and picking up the odd component here and there (most notably the Mechman 320a alternator and the XS Power D6500 XS AGM battery. I had planned on doing a system in a Supercrew 4-door and had also picked up a DM810 thinking I would integrate it into the factory (non-Sony) system. Some time in 2019 I decided I was sick and tired of having payments with wheels and made a few decisions that included trading my 2018 Lariat Supercrew in for a well maintained 2016 Supercab (the one with the funny half suicide doors). I had enough equity in the 2018 truck that I barely had to come out of pocket on the 2016 truck at all and I then had a solid work truck with no payment. Now I've got a solid work truck that I plan to drive until the wheels fall off. I also have a daily driver sedan that most of my mileage goes on and I only use the truck for towing, material pick ups, dirty job stuff - you know - work truck stuff, so I'm hopeful that it has years of life left. The build: 2016 F150 XL Supercab Ecoboost 3.5L Mechman Elite series 320 amp alternator XS Power D6500 XS Series 12V 3900 Amp AGM Battery A ton of KnuKonceptz Kolossus Fleks tinned OFC 1/0 and 4 gauge cable A ton of KnuKonceptz Kord OFC speaker wire (10 gauge - 16 gauge) Kenwood DMX906S + Kenwood DRV-N520 Dash cam (They integrate really well) Cadence DSP4.8 DSP that I picked up as new old-stock so long ago I don't even remember. I went with this instead of the Audio Control DM810 thinking I could save the DM810 for a build down the road where I was integrating with a stock system) 3-way actives in the front doors/A-Pilar DD Audio AW65 Mid bass drivers DD Audio AW3 Mids DD Audio C series silk dome tweeters 2xDD Audio 712D Dual 4 Ω voice coils wired down to a final impedance of 1 Ω across both drivers Custom built ported enclosure tuned to 28Hz (the published FS of the speakers) DD Audio C4.60 class A/B 4 channel driving the tweets & 3" mids DD Audio C2.150 class A/B 2 channel driving the 6.5" mid bass drivers DD Audio DM2500a class D mono block driving the 12s wired at 1 Ω Custom amp rack with 8 be quiet Pure Wings 80mm fans (4 ingress and 4 exhaust) All the sound deadener I had on-hand Ampeak 1000W inverter for running 110v stuff (comes in handy when you get somewhere and realize your battery tools have dead batteries) with the Ampeak remote on/off switch Soft tonneau cover LED bed lights Swing out bed toolbox The whole build spanned over several weeks (maybe even a few months) working on it when I had time and trying not to rush. All the fab work was done with normal power tools with the exception of one box trim piece that I used a 3D printer to make. No CNC or Laser work. I'll stop here and respond to the post with the build log pictures as I don't know if the site will time out if I spend an hour writing up a post

Here we have a competitors alternator that came to us not in working order. Have a look at what was found

ok so i have been wanting to get a 170 amp high output alt from mechman for almost a year. then i finally get the money and order it for my 2001 oldsmobile alero 2.4L. i wait a week and then i get a email that says the tracking code and everything. about a week later i receive my alternator. everything looks great and im super excited to put it in my car. go to my dads shop to put it in. we start taking out the old one and my dad is telling me that shit aint gonna fit. i just keep telling him dad its made just for my car and engine. so we try to put it in and the post and plug are on top of the alterntor instead of on the front. so the post is poking the intake and there is definitely no way this would work. so i take it out put my stock one back in mad as hell that i spent this money and it doesn't fit. so i call mechman and they tell me to send them pictures of the stock and the mechman alt. so i do and they tell me i can send it back so they can move the post and plug to the front were it was suppose to be the first time. i ask the guy brian i was talking to if i could get a shipping receipt so i wouldn't have to pay for shipping since i shouldn't have too. and he tells me we can send it back for free but you have to send it to us and pay for the shipping. so i get real pissed and he just says thats all we can do for you. so i said whatever and called them again and talked to someone else and i talk to josh and he is real cool trying to help me out. he tells me if i return it with my money and then email him a picture of the receipt they would reimburse me. so im like hell ya i guess things are starting to workout after im about to kill myself cause all the bullshit. so i send it off in about a hour and email him the receipt and tracking number and all he says is wow!! is shouldn't of been that much. it should of been no more then 20 bucks he said. and asked if i had special insurance or anything. i emailed him back saying my mom brought it for me and that was the cheapest they could do. which was 39 bucks. so its today and he still hasnt emailed me back from yesterday. so i email him again. call and couldnt get a hold of him. so now im just sitting here pissed cause i had to pay 40 bucks to ship something back that should of fit in the first place and they wont even give me my money back after they promised to reimburse me since its to expensive to give out shipping labels for free. so im just stuck now waiting to get a email.

Will 3 D3400's and a 320 amp Mechman S series Alternator be enough to run my system with a BC3500? it won't see much comp time but it will be daily.

Looking for more output at idle from ANY alternator on your 1999-2012 GM truck or SUV ??? Look no further !!! We will soon be stocking OVERDRIVE harmonic ballancers for LS series GM trucks and SUV's with 4.8L, 5.3L, 6.0L, and 6.2L engines, 1999 through 2012. This replacement ballancer has a larger diameter 8 rib crankshaft pulley on it. This means that your alternator or alternators will be spinning 10% faster at idle, which can mean a 50 to 100 amp increase at idle, depending on which high output alternator(s) you have. If you are running multiple high output units and have a problem with belt slip, we also offer an 8 rib conversion that comes with everything you need to swap to an 8 rib belt, increasing belt traction and idle speed at the same time !! (alternator pulleys sold separately) On top of that, we will also be stocking SCT and Diablosport handheld tuners. These devices upload a high performance tune to your vehicle's engine computer that increases HP, and ALSO allows you to increase your engine idle speed to up to 1,000 rpm. The combination of a tuner, crank pulley, and our 370 amp Elite series unit would result in over 300 amps at idle !!! Watch for demo videos soon!!

Ive seen guys on here talking bout 0 guage welding cable is cheaper than 0 guage power wire, is this true and were to buy. its seems like you can get cheaper 50 ft of 0 guage power wire then welding cable online.

wats up guys , im wondering wats the pros and cons of running tool maker dual inputs to a crescendo bc3500 or sundown 3500? like will i see a power increase or is even worth it to buy them.

hey wats up fellow bass heads, im noticing a a drop in my voltage and i was wondering would it make any diffrence if i disconnected the extra runs of 0 guage coming from the back to alt to the front battery then alternator. like basically my extra runs of 0 are connected to my alternator meaning power wire. but i was thinking bout taking them off and connecting them to the front battery then to the alternator., would ait make a diffrence

Does aluminum bus bars give you a better connection than just using power wire to connect batteries... if so wat the best size to use like 1" thick 2" thick etc.
