Okay, my brother picked up a JL Audio 1000/1v2 This thing has so many filters/settings it's very different from my sundown. What do they all mean? I've never messed with an amp with all these kind of settings. "Q" Center Freq Infrasonic Freq Filter Freq Mode/Slope -- Off/12/24 Input Voltage -- Low/High Input Sens

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

Well a few days ago I got a FI Q powered by a Sundown SAE-1000D. So far I'm loving it and everything seems to be working right. I previously had a different amp with a pair of sundown SD-1's and I used all of the same connections. The only thing I really changed was the ground. As ghetto as it may seem, I had a 4awg power cable with 8awg ground. Since I just bought a new to me amp, I didn't want to run it this way anymore and replaced the ground with 4awg. So today I was heading out to the store and I happened to glance into the trunk. I have a Bmw 325i sedan with folding seats and I had a clear view of where the fuse holder is. I kind of noticed something but wa…

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 are some other amps other than the sundown sax-100.4 that can run 2-way active?

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?

need diagram for wireing more than 2 - 8v batterys together ? is there a sticky with pics ???

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?

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?

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…

Is it ok to use only two channels of a four channel amp?

for 4 sa8's d4's so i csn run 2 ohm or .5ohm nominal..... ive got a dc 270xp alt and 2 discovery dt12-4000 agm g31 batterys. was thinking a saz2500 @ .5 nominal

This going to be my first time installing both a ho alt an wiring/installing a battary bank I feel like for the most part I know what I'm doing but idk how many runs of ofc 0 gauge I need from my front batt (duracell AMG 55ah) to rear bank (5 duracell AMG g31 105ah) 580ah total *My battary bank is going in the middle of my van I'm thinking 8-10 ft runs of wire* maybe less 240 mechman alt Sound qubed q1-7000 probably going with skyhigh ofc 0 gauge

I'm lookin at a few units with time alignment and won't break the bank. Eclipse and Clarion are the ones I've paid specific attention to. I kinda want to keep my Eclipse 8053 but would like some of the new features like USB/bluetooth. I am looking at HUs with time alignment and possibly a decent crossover built in but not necessary as I am thinkin of getting an external one. Anyone with first-hand experience or links to reviews?

I'm looking into the 8455, but Eclipse has the worst site in the world with little info. I'm wondering if the aux input is direct connection, or do you need an adapter like on Pioneer and Alpine? Also, anyone friends with any dealers that will ship to me? The local dealer here is horrible and I refuse to give them my business. Thanks!
