  1. Yo i bought an earthquake mini d 2500 amp thought it was 0 awg input but it has only one 4 gauge input that has to be fused at 100amp This amplifier is supposed to output 2000w rms at 1 ohm and somehow 1800w rms at 2ohm Doesn't this mean i need like 18v to run this at full potential because it only has a 100a fuse rating I also have a kicker cx1200.1 that has the same fuse rating and 4 gauge inputs that does only 1200w rms at 2 ohm wich seems fair I feel like something might be wrong here Just tell me what i should do and if u have ever seen something like this (if the mini d2500 puts out 1800w rms at 1 ohm and does it without setting shit on fire i'll be happy) I'll be happy to hear from you guys Thanks in advance
  2. Hi there, anyone knows anything about this amp? I saw that's it's rates 2.9kw @ 1ohm, that's max or rms ? I cannot find any information about it. Nothing on the amp performance, and on the forum is one topic from 2007. Guts in the attachment Thanks a lot for any information.
  3. So my two re audio srx 12” 2ohm are wired to my Rockford fosgate prime 750.1 wired to two ohms. It was working fine then one day it started cutting out. All the wiring seems fine. I have checked all my wiring by using a multi meter. The only thing i have found is that when driving and subs are connected and the multi meter is connected to the speaker wire and set to ohm or voltage it jumps up and down. But when everything is unplugged and sub box and tested on ohm is reads 2.5-2.8( crappy multimeter). I can’t tell if it’s just the crappy speaker wire i bought from auto zone(12 guage), a bad ground, or something wrong with my amp. PLEASE HELP!!! Thank you!
  4. I have a DC audio M3 8" Dual ohm sub 600 watts RMS 1200 max and I do believe i burnt the coil. Im running a Hifonics Brutus 1400 1 channel mono block class D. It's wired correctly and ran fine for the few months, left for a job out of town for 5 weeks my truck sat parked. Now the sub smells burnt. If you'd like a picture of how the amp is tuned i would gladly email it to you.
  5. I currently have a box in my car holding my 2 NVXvcw154's and running a Skar audio 2000watt amp, but... the Problem I'm having is the box I'm using is tuned high (i think, its been years since i made it) the new subs i put in will bottom out when i turn them up to a nice volume. I've remedied this by turning my subsonic filter up but its pretty high up there, more than 75% to max. I was wondering if i've designed this new box correctly. I've added a link to the subbox.pro designer and plugged in all the parameters of my subwoofers and the limits of my trunk. I don't know if my port area is too big or too small for the speaker size and box volume. I realize that the box length has a bit of an issue with the length being longer than the box. I plan on angling it to make an L port to fit it in the box. If you have any knowledge of box building and you see any problems with this build please let me know! I want these subwoofers to perform to the best of their abilities and that means I need to get this box built correctly. I appreciate any help, This is The new box This is the page with my Subwoofer Specs.
  6. Hey Guys! I am in need of some help inconnection with my battery connection. So at one point it occurred to me, when I played from my batteries only, one is taking more time to recharge than the other. It seemed to me, that the balance between them is equal(I think I was wrong), so I decided to investigate. I know that battery one takes the more "beat" than it should, because it takes 4-6 hours to recharge opposite to battery two which is only taking 1-2 hours, when placed on a charger. I also put on a test tone to see what is up, and started clamping for some amperage measurements. By this I found out battery one is providing 16X MORE amps than battery two. So here is the deal. I do not know what causes this problem, because I have 0 AWG copper wires, and I have 15 inches of wire between batteries counter to 4 feet between the batteries and the amplifier, so I don't think it is the wires. What I could come up with as a solution is to get a dual 1/0 to 1/0 power and ground input for the amplifier for balance purposes. Do you think it will help? Or is it just a waste of money? If you have any solutions/ideas please share it!! Thank you in advance!
  7. So I’m getting no output from my subwoofers. Brand new pioneer deck and brand new audiopipe 2k. I have 2 d4 12s wired to 1 ohm and that’s what it reads at the amp when the car is off. But when I turn the car on it reads -2 or -3ohms so that’s obviously why I just don’t know what to do I’ve tried everything. Tried 3 diff sets of rcas
  8. Remember the Bucket o' Bass series? Its on Steve Meades channel. In the video he uses four DC Audio Level ones. I decided it was a good idea and built the box and used those subs. My box design is dead near-perfect, my amp has plenty of power, and the subs are high quality. My only problem is during the test bump, I blew one of the subs! I don't know how. The subwoofers were NOT reaching anywhere near xmax, even on the extreme lows. The subs weren't even really being pushed. They were slightly over powered, but I didn't even turn the volume up that far. It was at 9 tonight. I just don't understand what I did wrong. I'm super new to this, but I'm pretty sure I did everything right. Help me! Shit I'm using: QCA4000d: 2000w rms Quantum Audio Amp. (4) DC Audio Level 1 12s Homemade enclosure 01' silverado
  9. Question for any person, I'm building a box for a friend. He has 2-JL Audio W7(not the AE) svc 3ohm subs with a Taramps 5000.1 mono but switching to a JL 1000 mono amplifier. He wants a sealed enclosure but he likes loud so I suggested a ported box. Doesn't want that, so I had mentioned having both types either going 4th order being sealed and ported or go with a 6th order. By experienced ppl out there, which type enclosure would be best for these 2 12W7's? The system is going in a 06' Buick Regal. Thank yall if any ideas on this
  10. Hello, this is my first post on this site but ive always found this website very useful. I was wondering if someone could teach me some about transmission line enclosures i have a single 15" skar evl 15 that i want to build a t line for. Its gonna be in my room so space isnt a problem. If anyone could shoot me some ideas that would be great. Im aiming for it to be tuned about 30 hertz
  11. Hey guys im doing my first build 3 skar evl 15s dvc 2ohm on a ts 3.5 I was gonna do a flat wall but everyone I know personally who does comps says if this is for me anf not for comps I need to do a fourth order cause it's more musical and has more bandwidth i wanna do demos but really i just love bass I've tried bass box 6 and win isd and on regular ported walls it wasnt a problem to get good response on the graph but when I try it with the 4th order calc no matter what i do I cant get the tuning right i want it tuned where its peaking between 32 and 55 Hz tops I don't know a bunch about it all i know is i love bass and I am a noob to all competitors I've read over an hour a day for 9 months and finally got the basics but still know nothing theres so much to learn but im dedicated i got everything for it ho alt batts subs amp and all power cable ran but cant build the box correctly cause i cant do the specs and don't wanna mess up the subs from doing it wrong I know it's time consuming and has no benefit to you but if someone could please help id be eternally grateful the box max external specs are 42d 36h 40w so it leaves plenty of room for the 2:1. And the subs rec enclosure are 3.5-3.75 sealed 3.5-4.0. Ported thanks so much for even reading this ridiculously long post if someone would help I will build and show results so they can know there time wasnt wasted -hooplah-
  12. So my 2014 Ford fusion is a great for tight spaces. And having trouble coming up with a alternator bracket design. But dream system simply can't happen without it. I atleast need some ideas for a bracket, mounting points and such unless someone may be willing to make me one. I've figured out (and I hope correctly) the max I can put in this thing is about 6k-7.5k of bass on 4 or 5 u series 10" sundown subs, and 800 watts of crescendo mezzo components on an c1100.4. If 6k then crescendo 6k amp, if 7.5k then sundown amp. I'mguessing 3 or 4 270 amp alts plus stock 170 amp alt, 3 or 4 xp3000's for secondary, 1 d3400 to replace starter battery, all alts 2 runs 2/0, (how should I connect wires in this system?, there are many options. All power to starter bat then starter bat [same amount of total runs to rear secondaries 2/0] to first secondary and so on or starter bat to each secondary battery [one run to first, one run to second and so on] then secondaries to amps using 1/0 and dual inputs to amps. Then for grounds, from alts, ground to chassis or run ground to chassis and starter bat then to secondaries, or all battery and alts ground to chassis? That's for audio, then I'm estimating on the high end 1000 watts for lighting system. Also do I have enough batts and alts in the system planned? Am I short or to much? Should I add lithium if so how do I wire that into the system? This is a link to engine bay pics for reference. https://photos.app.goo.gl/1PvssHTzAfz4qmW78
  13. Hey there, I have two 15" Earthquake DBXI subwoofers that are currently in a sealed enclosure and I'm looking to go ported. My car is a 2003 Monte carlo - My amp is an Alpine 1k - The trunk space available is 36" wide - 31" Deep - 16" Tall The subwoofers are 6 3/8" from the bottom of the mounting bracket to the bottom of the magnet if that helps I listen to a lot of rap (Gucci Mane, Future, etc) and I'm a huge fan of low bass (Decaf <3) but I'd still like to be able to handle mid range bass also Im not opposed to any style of box I Just want it to sound better Please let me know if you need any more info! Will appreciate any help someone can give!

  16. I am in the process of sealing off my trunk and I still want to be able to get to my spare tire or have trunk space if I go on a trip. Here is my idea and I was wonder if anyone has done it before. I could make a frame slot that is the size of the outside if my box and secure that to the trunk and seal that off in the trunk and make a lip on the front.. Then I could slide the box in and out at will. I would make it a tight fit and have a way to lock it in place so that it will still have no airflow going past the box. Would this work?
  17. Im looking into some train horns, and I just dont know much about them... I found the Hornblasters Rocker 228 horn kit, and for $320, im just not sure how it holds up for the price. Im just looking for some insight on train horns in general, and if that kit is worth getting. I want loud and deep, but I dont want to spend $1000. The $300ish price range was what im looking for, so if anyone knows something better for that price, that would be great. I dont need anything crazy, just enough to scare my friends if they walk in front of my truck lol. Space isnt much of an issue either. Thanks in advance for help on this
  18. Okay... I know most people hate capacitors..but i like them. Anyways I have two twelves and two tens. I have a 10 farad capacitor. One of my amps only has one set RCAs and the other has two. Can anyone help me on wiring this? Any help would be greatly appreciated. Thank you, Wade
  19. Ok and who could I talk to about just figuring out everything? How many ohms, specs on the sub, or just what the heck inverting it does?!?
  20. I just ordered two 12" Alpine Type R SWR-12D4 and a Hifonics Brutus Elite 2000.1. I need to build a box to fit in a 2000 Ford Taurus. I am fairly new to the car audio scene so I don't know how many hz to tune the box to or how hard it is. Just looking for a cut list and any suggestions on how I should build this.
  21. I was running subs today at about 1/2 volume of max . My system has been tuned with the dd1. No eq or bass boost everything set flat and 0. Today with volume lower then usual... I heard a noise that was a loud buzz sound and then it sounded like a slinky hitting a wall. I immediately pulled over and the sub was still playing just not as loud. I pushed on the front and I can feel the coil rubbing. The sub was not hot or overheating. I had an old JL audio blow before but it usually would be super hot and have dust/smoke coming out the holes. This sub is a newer w3v3 that I have had for less then a year and purchased as a pair. The other is completely fine. When I put the multimeter on it, it read open but when I move it, it jumps around in Ohms alot. Could someone enlighten me or what may of happen? Is it blown or did the suspension go on it?? I plan to get it repaired by JL because they charged a flat rate repair of $150 on w3v3s. Both tinsel leads look perfectly fine and the spyder is untouched. From within the cone I can feel the whole shape of the coil pressing forward.
  22. So just to state this is not a VS thread. I just want to know what the advantages or disadvantages of say running 2 12s that are 1k rms ea over say a single 12 at 2k rms or even a single 15 at 2k rms
  23. Hi everyone I'm new to the forum. So I have had a Sound Stream Picasso 5 channel for the past 4 years and it just died on me and now I'm looking for a new amp. I have been looking at the Zapco st5, Helix Dark Blue 5, Jbl ez5, and the Polk D5000. Which one should I go for? Any other suggestions are welcome. I would like to keep the price around 300. Thank you in advance, Kevin
  24. I have a 15 inch obsidian audio v3 dual 2 ohm and i need help with the design of a inverted enclosure. I can do the building part its just the technical part im not good at. I would like it to be tuned to 33-36 hz. I plan on putting around 600-700 watts on it.
  25. i just got a 2006 hyundai azera and the stereo needed to be replaced. i upgraded to a kenwood dpx792bh. its ounds great except there is a faint hissing static noise that plays all of the time. no matter what source its on, aux, usb, bt, radio, cd. even when its at 0 volume it has the noise. it doesnt increase in volume at all its just one constant hiss. i took it back to the best buy installer and he said it was unfixable, and probably a factory amp problem. i dont know much about car audio in general and wanted some second opinions. Thanks!
