If I have one battery, is a good or bad idea to run the negative cable from the amp to the battery? Did the chasis have more resistance than, let say, 14ft of 4 gauge cable? I'm asking that because I read that grounding the amplifier at the battery minimize voltage drop, don't know if that is true.

So my amp is 3500watts and my alt only puts out 90amps....so if i hook those up is my amp gonna draw as much power as it can, or does it only draw a certain amount of power depending on how much i turn up my subwoofer?......................................Actually i just took a look at my amp and their is a level control im guessing for the power of the amp,,,,,,,,,,,,so ill just adjust that,,,,but can anyone tell me what the max rms i should put out ????

I'm currently in the process of designing/setting up my first system. I currently have a pioneer deh-p690ub head unit but haven't been able to figure out all of its features yet. Can i have an active front stage with this headunit? I have a set of focal 6.5 V2 polyglass components, not installed, but i'm thinking about returning them to tweeter because after browsing through the threads here I'm sure i can get a better front stage for the money. Any input would be helpful, thanks.

I have a 2002 honda civic si and I just installed a 200amp alt. The sys is charging at 14 volts. The batt light, on the dash, stays on. I have a batt under the hood and 2 in the back. Any ideas?

So i was at my local shop and i was talking to the manager about buying a alpine 9887 and he was trying to tell me that I was making a huge mistake and active isnt worth all the time spent shaping the crossovers and then he told be the 9887 will not low pass the mid up too 2500 hz like i want to for my mli-65s so i ask all of you is he right that i would need more processer or is he full of it. Thanks for any help Brian

My neighbor happened upon a xtant 3300 its a big ass chrome amp unlike anything ive seen before. I went over there and hooked up on the mono sub channel to a couple Memphis 15's and it sounded good but what im wondering is what else can it be used for I googled it and found its a 3 channel with 5 channel capabilities more SQ oriented but what is this thing worth? Also ive never seen an amp like this without knobs and little plugs instead. I would have taken a pic but it was night and my cell wasn't capturing it well. Anyone have any knowlegde on it? I can probably get it for pretty damn cheap or trade my RF 450.2 for it.

My lights don't dim or anything, maybe slightly if i crank it up. but its an 05 Civic, stock alt and battery...is there still any concerns i should be aware of? my amps: JLA 400/4 (using 75x2 currently) class a/b MTX 1501d (using about 1400 watts, 1.33ohm load) class d 4 guage power. Overall, system seems fine, nothing cutting out..etc. The OEM alt is a Mitsubishi, no idea how many amps it pushes but i'd be suprised if its over 100a. if lights don't dim, is it ok?

I have a dc level 4 (with atomic magnet) on an apk 2500.1 amp. When I play songs with high bass notes like Versace-Drake the amp cuts out and protects itself and stays in protect until I restart my car. I was wondering your guys Input on this problem as of right now I'm at a loss for ideas. I've tested all my wires and they all have power I have a extra battery on top of a 20 farad capacitor so power should not be a problem at all

Looking towards buying a new amplifier for my Fi BTL N2 sometime this summer and looking at my options. I can obviously do as much research on my own as possible but numbers are just numbers, Id like to ask people who have experience with these amplifiers and your opinions on what I should get. I have around 4 different amplifiers that Im currently looking at, all around the same prices. Dont really want to spend over $700 and will buy used if need be. 1. Sundown SAZ-2500D (used) or SAZ-3500D (Refurbished) 2. DD M3a (new) 3. Orion 2500D (Found one locally used) 4. Crescendo BC3500D (new) Any input much appreciated and also FYI, Im running a stock battery upfront, big 3…

Alright so I have been waiting to get money for 1/0 wiring and then my friend who is in an automotive electrical class in a local college here messaged me and said that he thinks 4 awg would be big enough for my big 3 Since my alt is only a 70 amp alt and He read that 4 awg should carry up to 150 amps.. At least in that short of a run (1ft-5ft runs) Just wanna make sure if this will work before I buy it in about 45mins. I dont have enough yet for all the 1/0 but I have enough to afford 4 awg if it is good enough now. After he said that i figured well 1/0 can carry more current at a time and quicker.. but.. If my alt only puts out 70 and 4 awg can carry 150.. Is there…

Greetings Folks, I was in to mobile audio around year 2000. Back then the Big Box Brands like you found at Best Buy were OK but the high end companies had a significant boost in performance. Lower noise floors, met rated power output, better thermal management, and cleaner sound. Today I see that the mainstream companies products pricing has DROPPED dramatically. I wonder if quality has suffered as well. Let me give an example... Sounstream 15 years ago was a high end company that made top shelf products. Today they are owned my the corporate overlords and have mainstream products. This amp caught my attention for price, performance, and looks. …

Ok. So now im looking for a new battery. My current battery ratings are CA: 650 Amps CCA: 525 Amps. The battery (EverStart) is bad tho. I dont know If I want a battery that replaces the existing one, or if I shold just get one and put it in my trunk. The battery I have now still starts my car, but in the cold its very close to not starting it. I want a battery that will start my car fine in the cold, and that will eliminate my voltage drops (Down to 13v from 14.5v voltage drops now when I bump my system) to go with my HO alt (160 Amp). After thinking about it after writing the majority of this thread, I should get an additional battery, and keep the stock right where i…

Hey guys quick easy question, my vehicle is set for a 24f battery, and I was look at xs batteries but they do not have one and said to just use their size 34. However it is slightly smaller so does anyone have any recommendations for a 24f sized battery? Or should I just go with a 34 xs?

I have a 400 watt class A/B amp running 2 10's right now. When I'm listening to rap music, after an hour or so, the amp shuts down from overheating, even if I don't have the volume up too high. Should I switch to a class D amp or would it not be worth it? I listen mostley to rap, but listen to rock and country too, I like to have acceptable SQ.

I got an audio pipe 1300 amp. Connected it up and it didn't work. I am now gonna try and return it.

first off is it better to stick w/ the same brand when dealin w/ amps for a system? i plan on purchasing the pioneer premier ts-c720prs comps powered by the zed audio gladius burr brown. i have a 10w7 (for testing purposes) and my friend says if i go w/ the gladius for comps i should get another zed for the sub. so now im thinkin bout doin two ppi art series amps thx in advance

Current setup is a Pioneer GM-D8604 4 Ch amp (4x150), this amp powers a 10" Infinity Kappa 100.9W (bridged) and JBL P660c components. I also have a pair of JBL GTO938 6x9's (un-amped) in the rear deck. This is running of the OEM head unit. I blew the coil of the Kappa sub a while back so I'm looking to upgrade. What I'm wanting to do is install an Alpine Type-R 2 ohm in it's place and run it off of a dedicated mono amp. I've already purchased the Pioneer GM-D9601 amp. This pushes 1200 watts RMS at 1-ohm. And add the rear 6x9's to the Pioneer GM-8604. This amp is installed under the driver seat, so I want the second amp under the passenger seat (it fits, without the wires…

I have a yellow top under the hood with the big 3 done in stinger 1/0 an a run of stinger 1/0 to the rear batts. One is a kinetik hc 1400 to a hc 1200 so 2600 total. Wired to two kicker zx1000.1 my question is the one single run of stinger 1/0 to the rear OK? It's ofc .

Should fit over the terminals also? Or what size should I be purchasing? Thanks.

hi, i am wondering which amp would be better, i will be running my front stage with one of the other and it will be active but the processor will be my hu ( alpine cda 9887). ok here are the choices: new Eclipse Xa4000 bought online so an iffy warrenty. or a B stock sax100.4b that the bottom of the amp is slightly dented but has a 1 year warrenty with sundown.

hey guys, ive been lookin into a rd designs 5250 just wondering if they were a strong amp.. thanks!

I just bought the hifonics brz1700.1d and the Shuriken SK-BT60, do I conected like this and ground the second battery to the chassis. I have a 95 honda accord

I have two giant bulldozer batteries in my barn, hold charge fine. All they say on them is Deka 8C12, 90 min, and extreme deep cycle. They are open cell with acid in them so that's why I'm worried. Would they work as secondary batteries in the back?

ok i just got a alpine cda9855, and the preouts say 4 volts. i am going to be using a us amps ax1000de and a us amps merlin md41, and the input gain on the ax1000de is 150mV to 3 volts. and the md41 i dont have the manual on. so my question is. will a 4 volt preout work with this amp, and if anybody knows if it will work with the merlin as well. also what exactly will the difference be between 2 volt preouts and 4 volt preouts. becuase im pretty sure 4 volt is better. thanks
