I have two kicker comp q 12’s dual 4ohm and looking at two different amps , the kicker cxa 1800.1 and the D’Amore engineering E1500.1 . Love the idea of the E1500 but I feel like the kicker would be better power wise just not sure .

so... i was at BestBuy the other day. just looking. and came across the cda-117. ive always liked the look of the unit and the fact that it has 4v pre-outs... well, i looked at the price and it said $177 clearance. (this means once they are out... they're out) so get it while you can! i was like WHAT!?! so i bought it on an impulse buy. lol. its about #50 from Crutchfield. and lowest i can find is about @285 from an UN-authorized dealer. http://www.crutchfield.com/s_500CDA117/Alpine-CDA-117.html?search=cda-117&skipvs=T SO... if you guys are looking for a nice HU on the cheap, go snatch this up! i was honestly gonna buy the other 2 they had when i got my paycheck and r…

I have a 5500watt amp that is 70% efficient which makes 3850watts to use. I have a 250amp alternator and my car uses up 27amps of that alternator so i have 223 amps from my alternator. i have replaced my BIG 3 with 0 gauge, and will have my system (an 18" Fi BTL dual 2) ran with 0ga and the speaker wire in 10ga. If i worked everything out correctly using 13v i should be looking for a 31ah battery but i know that i want to go much higher to run off of my battery and not my alt. What do i look for in a battery? and if possible what kind would you all recommend? should i use more then one?

Okay, so I just hooked up all of my system last night. It worked flawlessly all last night, and this morning. So today, after work, I got in my car, turned on my radio, and my amp and everything turned on and my sub was playing, but I now have no music. At all. I know this is probably a n00b thread, but please help! I'm dying without my sub lol

anyone know if its legit, does it do what it says?

I drive a 2001 GMC Jimmy 4 door with a 4.3L Vortec V6 and want a 200 amp or so alternator to replace my stock one with and would like recommendations on what companies to look at. I am considering Excessive Amperage, Mean Green, PowerMaster and KnuKonceptz. There were others but I forgot them. Any feedback is appreciated.

ok so i installed my optima up front... what kindda battery do you think i should get to back up the amp i have? (kicker zx2500.1) I was looking at at a powermaster D3100 but idk if that would be overkill or not =(

Hey all. I have a Saz2500D and an excessive amperage 225 amp alt. Big 3. Autocrat gold batt up front. Anyways, my voltage runs off all over the place (it will drop down 2 volts and sometimes spike up to 16V!!!). Sometimes those spikes will even cause my radio to turn off for a second. Do you think adding a yellowtop or something similar in the back near the sub amp will help voltage drop and these irregularities? Resting voltage is 14.9V. Maximum drops are high 12's. Thanks

What voltage is bad on amps.

Could this be why my amp cuts on and off and goes into protect? I didn't pay it any attention before because the filament or whatever is in the center wasn't broken.

What do you guys use to crimp the larger power and ground wires. I don't have a need for the crimper that big much but got by with using the vise. Any other methods?

Will i need an aftermarket alternator if im running a hifonics bxi2608d? at around 2200~2400 watts in a 2000 Hyundai sonata with 1/0 power wires and Big 3 upgraded.....

I just got my new amp (hifonics bxi 2010d) and wired up, but yet Im getting no sound out put to my subs? :S I know the amp's getting power because the amp power light is on and the amp lights up blue. The thing that confuses me is that my old amp worked just fine and I go to swap amps hook everything up and yet no sound out put. I have no idea what couldcause this. Anyone know whats going on?

http://www.profilecaraudio.com/crossovers.htm i just need something to cross over my subs with, nothing fancy. what are yall opinions on this?

i got my hands on one.. it should be here in the morning.. i got it from a friend.. his dad has it in one of his old broken down trucks, (rednecks with lots of money) anyhow, his dads, brother did SPL back in the 90's and this is one of the amps he used... he knows im into spl so he asked what i would give for it... i know its a surf borad cheater amp fom years past, i knew them to be a pinkish purple but he says this one is silver, and about 4 feet long, he said the number on it is HC100 .... anyway. its in working cond, what kinda resale am i looking at on this?

hi, i have 2 sundown sd1 v1 12" and i am thinking about using them until i can get enough money to buy to system i really want so if i can limit how much i spend the better. anyway i already have a sundown sax100.2 that i was going to use to power them but the problem being that it does not have a subsonic filter on it. and i was wondering if i could get away with using my alpine 9887 crossovers and my sax100.2 crossovers and bandpass it, if that would ok an ok alternative.

I've been searching the past few days for a ~2000w RMS amplifier around the $200 price range. Here's a couple amps I'm torn between: Audiopipe AP1800D - rated at 1800w rms @ 1ohm --- 180-200$ Hifonics HiFi2000D - Rated at 2000w rms @ 1 ohm --- 200-230$ Quantum Audio QA4000D - Rated at 2000w rms @ 1 ohm --- 220-240$ These are not top of the line amps no doubt, but which of these three would most likely put out the cleanest signal, do close to rated power and most efficiently? And any other ideas on other amps around this price range around 2kw rms? (No more than $250)

Looking to help a friend find a cheap amp. $150-$160 or less, needs to be 1 ohm stable, at least 400-500rms x1 at 1 ohm Thanks guys! edit: powering my old 12" CVR. (400rms)

Ok so I got a new to me truck. It has a stereo in it already which is good. A JL 12w1v2 in a sealed truck box, hertz components, a rockford punch 300.1, and a kenwood excelon x797 I don't like the x797 so I put my kenwood excelon x998 in it. I can't see the display at all on sunny days with this headunit. I want a new single din with 4v+. I don't care about active, or a CD player. If it has a CD ok no big deal. I love all the features of my x998 but its just no doing it for me anymore. I'm more about features. I will not spend more than $250 so that leaves out the 80prs it seems. I have been looking at alpine. kenwood, pioneer. I think I'm liking the al…

So my jeep has a stock 160a alternator. I plan on upgrading to about 2k rms here in the next few weeks. I was wondering if that alternator would cut it if i did big3 and got some extra batts. What do you guys think?

i need to get an 0/1 gauge distibution block with 3 or 4 4 gauge outs. i plan to run 8 gauge into one of the outputs, to my 35x4, this wont be a problem right? been looking at the blocks on ebay and i found a couple that look alright to me that aren't too expensive but thought i'd get some opinions before i buy some piece of chit and it wastes one of my amps. heres what i was looking at, does it look about like what i need, or is it with it to go with a stinger? is one fuse as good as another? in some auctions they say midis are better, but seems to me as long as it blows at its rated amps a fuse is a fuse. opinions? http://cgi.ebay.com/EFX-1-0-GA-4-way-DIGIT...1QQcmdZVi…

Here's the thing, i was considering getting 2 - 12" older model p3s, 2ohm subwoofers, Power Handling (Watts RMS): 400 Watts RMS 800 Watts Max With this amp http://www.rockfordfosgate.com/products/details/p1000x2 Rated Power (RMS Continuous Power): 300 Watts x 2 @ 4-Ohm 500 Watts x 2 @ 2-Ohm wired with the 2ohm version If i can't find the older ones in 2ohm, i've come across the 4ohms, but wiring them would only deliver 300 watts, is this enough or do i have to get the 10"(which only require 300)? going in the trunk of a car, have 39" width and want to do less than 8" deep, ~16-18 high(considering leaving a spot on th…
