I am getting 15's very soon. Two aq hdc3's off of a 2200d. My electrical now is a 200amp alt, 1/0 big three, and yellow top under the hood. All this is on a diesel engine, that of course runs at lower rpms than a traditional gas engine. I have the smallest pulley I can put on the alternator already installed, and am scared the voltage may not be enough to back this system. Would another battery be needed? If so which one, and for the best price? By the way, this is a daily setup.

Will I see a big difference if i update from an aq3500d (old one 3500 watts) to a saz-4500? I am looking to get my 2 dd3512e louder. Would this get me there?

I'm looking at two amps a sundown 2500 or the crescendo 2000. I have the power to run either amp. I will be running it on a pair of disadvantages 12's.2 ohm daily, .05 ohm at competitions. What would u guys choose?

According to PowerBass 3XL product info, a Class D amplifier heats a subwoofer voice coil 2 to 3 times hotter and faster than a class a/b amplifier. Is there any truth to this? I'm not an electrical engineer, nor a amp design expert, but I've never heard this before. http://www.powerbassusa.com/3xl-series

So if you put the power, ignition and ground from the head-unit on the battery directly and there is no power, is the head-unit faulty? Because i only get a tiny tiny spark on the positive post... other then that, no reaction. http://www.alpine-usa.com/product/view/ida-x305s/

Who can I talk to about having a Treo 750.1 fixed, I've been told THE fets are fried.. I'm not 100% sure if anything else is fudgeed or what, but I'd like to see how much it'd be to get fixed, rather than buying another amp.

I know it's hard to do apples to apples, different ohm loads "Output Voltage and Impedance 8V/55 " different THD's "Total Harmonic Distortion (THD): 0.008%" yadda yadda...frequency range, voltage. I have been looking to switch from Alpine to Eclipse on the simple thought that Alpine is usually 4-5V where eclipse can be 8V and upwards. Help me out here guys!

Hey guys, right know i currently have a jl w6v2, its being run by an ancient rf amp thats putting out around 500 watts or so. First question... Would i be safe to run this amp at 2 ohms for the w6. Second Question... Honest opinion on the amp and overall quality...

someone please help me out...i just bought a system but completely forgot that i had to buy a wire harness. and now that i'm looking for one, i cant find it. i got a 2005 Pontiac Grand Am, 3.4L 4 Dr Sedan

So i want to upgrade. But not immediately. like. May not upgrade for a whiiile. But have chance to get a bigger amp. so total hypothetical. I currently have an AQ1200 in my truck with full 4 gauge wires off stock alt and batt. could I, run an 2k amp off of this set up. Never goin over like, probably quarter gain to half. (prollly long time before that amp would clip) 2k amp being a db drive okur 2k. I know anything above 1.5k comes with 1/0 inputs. But could i run it off of the 4 gauge til i can upgrade the rest of the set up is my basic question. Any of your guys' vast knowledge would be great!! thanks in advance!

I know I need to fuse b/t front battery & 2 back batts. What size fuse should I have? Also, should I fuse anywhere else?

My bro is looking for a head unit for the 2007 F150 he just bought. He's wanting a double din with these options: Blue Tooth capable Satellite Ready Nav System – Easily updatable (prefer no DVDs, but flexible on this) Traffic Receiver Back Up Camera capable He's looking at this: http://www.crutchfield.com/S-ZeS1vjeeznh/I-rEMTcVSL/s_105NT3HDT/JVC-KW-NT3HDT.html?ssi=0&tp=27996 but I recall from my head unit shopping a couple years ago that gurus recommended to stay away from JVC. He's having trouble finding another brand with all of the options he wants. Any recs?

Yes hello i have a question about wiring i have 2 us amps md1d and 2 kicker l7 15s i have 4ga wiring sometimes my fuse blows every now and then when i turn it up my homeboy has almost the same set up but has 0ga wiring and has not blown a fuse so my question is should i go to 0ga wiring and how should i run it. Thanks

So I'm sick of borrowing other peoples DMM's and O-scopes. Anyone hear anything about this http://www.parts-express.com/pe/showdetl.cfm?Partnumber=390-500&FTR=390-500 Also can anybody suggest a decently priced handheld O-scope? Thanks, Rick

Hey guyz, i heard 2 pops about 2 seconds apart then hit play on my iphone and silence. Ive had 2 different amps on my door speakers. ONe was an alpline mrp300.4 or something like that and now i have phoenix gold octane 9.0.1. both are 5 channel and i used only the 4 channels for my door speakers. I have pioneer 5800mp headunit, the pico fuse is blown so i catch a goodbit of alt whine and noise. which leads me to think that has something to do with the amps blowing? Could that have an effect on the amp if the fuse is blown? I checked all fuses and connections. It wasnt playin music when it happened either, which is weird to me. Please help me fix what im doing wro…

I just installed a second yellow optima I have my two amps wired and installed I have two extra sets of ground,power, and remote electrical taped at the end I want to be ready to just plug and play when my two new amps come in the mail I'm seeing 12.6 at stop signs and hit, but do not stay, at 14.4 when getting on the freeway the volt meter is wired to the new battery postitive I'm wondering if maybe I need to charge this new battery some more before i expect 14.4? It was made 05/12 everything is fused with knu including the alternator with high current 300amp fuses big 3 done in 1/0 the alternator is a powerbastards 220 amp, it does 109 @1500 (tested) any ideas? -thanks

After months of dealing with pioneers terrible customer service, one tech finally tells me that there was supposed to be a four foot usb extension capable of carrying the video signal from my iphone to the unit in the box. Unfortunately, even though ive been dealing with them since january, they wont send me one on them becuase its been over thirty days since i bought it. Anyways... I really need one longer anyways. It needs to be able to carry the signal and be at least 12 ft long. Any ideas?

Im upgrading my BASS and i was thinking of buying the rockford fosgate T20001bd, anyone know these amps. I was going to try to buy a 12" btl to run off of it as well, do u think it is a good pair up?

anyone ever had experience with hifonics? i've heard a lot of trash talking and underrating, but still even if it's underrated, it would be only pushing around 1000 or so... that's still a good deal for only 180$ but if these amps just absolutely suck, is there any amp someone could suggest in the 250$ range that would produce about 1000 watts rms? thanks a lot

Hey everyone...I am in the proccess of ordering my 2 18" btls...and im curious..after I upgrade my alt..and work the big 3.... batteries... do I need to go with Powermaster batts. or will several optima batts suffice? if so what color and how many?? 2 18" btls fully loaded 2 saz 3000dz and all the upgrades thnks guys...ill post pics when I recieve the sub(s) Freddy Fred

I just had to replace my highs amp (jl audio 360/4) due to a malfunction. I was getting "engine" noise that came and went and also was present with car not running??! So I purchased an RF P400x4 to match my sub amps (t1500bdcp). I am happy with the amp, its the new model so it has input clipping and output clipping indicators, and a fancy set up disc with all tones and sweeps necessary (0db and -5db). So far very pleased. Also just fyi my pioneer p4400bh DOES NOT CLIP even at full volume. But that being said I had to go almost 3/4 on gains to get the required output without clipping of course. Also my sub amps are up quite high. So, long story short, I am getting very int…

I want to make sure my amp is set correct so I am going to try and pick up a digital multimeter soon. I have never used before though. Do I need an expensive one or any work fine. (http://www.sears.com/shc/s/p_10153_12605_03482141000P?prdNo=2&blockNo=2&blockType=G2). Using the equation in the topic my voltage should be about 22.3v. What would I set the dmm in the picture too?

I have someone interested in buying my two RF t1500bdcp amps. Ill be running two xcon 15s d1 in 4 cubes per sub. Which amp is better and why between cresendo 3500d and sundown 3500v2? And for that matter would it be wise to go from what i have to what im looking at?

I have scoured the internet last week and found nothing that can do this for real... I only found one amp, can't remember the amp but definitely could not do 200w x 4 @4ohm with a 60A fuse... I am trying to find an amp that can do 200w x 4 @4ohm so i do not have to get 2 amps that can do 200wx2 @ 4ohm. It's a space issue. Anybody know of such? And i do not plan on getting the 15K rockford amp.

Hey does anyone know anything or have an opinion about this amp
