Looking for some suggestions for good quality 5-9k rms amps. I have looked at some, but just want to see what some of you guys think. Thanks.

Here's my old school Alpine MRV-F352. I used this for about 2.5 years or so and one day the 5th channel when out. The other four-channels still work fine. I've sent a few pics of the damage. Could some one tell me what I should do with this amp. I don't really need it anymore, but I don't think many people would want a 5 channel amp that only has 4 channels that work. The damaged part is in the upper right hand corner. You can see the burn marks just under the model number. Closer pic of the damage Very close image of the damage I don't know very much about amp internals, Would this be a quick and inexpensive fix, or is it just not worth the effort. Thanks!

I am using two of these from 2003 or 04. They are the silver heat sink with the blue light up logo. Here is my set up, I have 1 ea. dual 1 ohm woofers wired to 2 ohm on each amp. I installed the 2 15" SSA xcons in the enclosure that Quentin built for me and I have spent most of the afternoon trying to tune this. I honestly have been very dissappointed as my output has been very modest for most of the day, but I switched the phase switch to 180 on one amp and WOW it woke up big time. So, I did the same thing on the other amp and my stuff is banging really hard now. This is more like it. My question is, why is this making such a BIG difference? And, do I risk damaging my xc…

So I'm going to buy a new car but before I do I want to finish buying everything i need for my system (alt+batts) my current car has probably 70amp alt and I'm wondering if it would be ok to hook up everything without a ho alt until I can get the new car really my concern is with ruining the batts (5 duracell amg 105ah g31) I'm getting a CTEK battary charger so could I just charge them every now an then or would it be to much strain on the batts? Thank you for reading Current alt 70-80 amp 5 amg duracell 105ah per Audio qubed q1-7000 2 sundown xv1 18s

My current setup consists of: -Advance auto parts group 34/78 up front -stinger spp1500d in the back -mechman 270a alt -Crescendo bc2k -Crescendo c1100.4 -Knu konceptz 1/0 all around including big 3 I was wanting to upgrade to something bigger (maybe a dc level 6 18). I am tore between 2 options...(both options will have c1100.4 and same batteries plus some later down the line) 1st: -Taramps hd5000 -2 positive runs of sky high 2/0 from front to back -3 positive runs to the amp -Big 3 in sky high 2/0 2nd: -Another bc2k strapped to the other one -1 run of sky high 2/0 from front to back -2 runs of knu 1/0 or 1 run of sky high 2/0 to each bc -big 3 in sky high 2/0 I can sav…

Heres the scoop: I went to put my sub and amp in my car, and was having a hard time getting the box to fit, so I thought I better check everything out to make sure it worked, and the amp keeps going into a protection mode or something. Its a Memphis PR1000.1 I tried to contact the seller because he guaranteed not to be DOA but won't get a return. I guess thats what I get for buying off of ebay But anyways, I was wondering if people could give me some input on which would be a better amp for my Fi Q in a LSQ installation. Kicker ZX1000.1 Sundown SAE-1000D I can get them for about the same price. Any help? Thanks.

Well my car (2004 Scion xB) is finally getting paid off next week so it's time to prepare for the upgrades. I just ordered my 12" Ethos and am planning on most likely a SQ2200D to power it. To begin with the front stage will be run off a Hifonics X14 X1200.4. The X14 is supposedly rated at 150x4 @4 and 300x4 @2. So total wattage should be around 3k RMS. I'm getting a 220 amp ho alt from Js Ultimate alts. I know I'm going to need a battery upgrade. Will I need an extra battery for the rear? My guess is yes, so I need to know what size and what to do as far as fusing/isolating/regulating the batteries and amps. I have some 1/0 cable for big 3 upgrade and will probably nee…

hello all i know i don't post much but i need some help, i have a 94 supra and i think it's time to upgrade the audio system. first let me say space is limited, i want to use a 5 channel amp because that's all it seem like i have room for. i will be using polk component speakers zx350.4 and they are 6 1/2, i also need some input on some bass speakers i don't want anything bigger than 10" i have a box to go in the stock location. any info will be appreciated. thanks.....

Recently i had to return a kenwood KDC-BT945U because it kept getting really hot and messing with the sound quality so im looking for something else. Im looking for something that has at least three sets of preouts (front, rear, and sub), aux input, decent ipod/iphone controls, and a good equilizer. Bluetooth would be cool but i can make calls on my phone so i really need something that will play music loud and for long periods of time. The guy at best buy showed me a JVC KW-XR810 but for some reason im a little hesitant with that brand. Id like to keep the budget under $300, but i understand you get what you pay for so going over wont hurt me too bad. I allready got a d…

alright, so i after taking my stock radio out and installing a my alpine deck i am getting a lot of noise. right now i just have the power going to the HU, no speakers no rcas or anything and im still getting the noise. wish i had the money to get my new speakers and amp to get rid of this! would that be a bad ground on the factory amp? here is what im dealing with this is the little factory amp for the speakers Uploaded with ImageShack.us and im not sure what these wires all taped up are for, goes somewhere in the dash that i couldnt follow Uploaded with ImageShack.us heres the 2 connections that plug into it Uploaded with ImageShack.us and this is how it plugs in…

hey all i am currently in the market for a solid 1500-2000rms amplifier to power my IA lethal injections. i have narrowed it down to either a rockford fosgate t1500bd or an american bass 120.1. I will be doing a small amount of competing but mostly just daily listening. I can get them for almost the same price but just cant decide which one would suit me better. my electrical will consist of probably just a second larger battery in the back and the big 3. give me some pros and cons of each amp if ya could! thanks!

Hey all I am new here and semi-new hooking up car stereo... that being said I need some help hooking up my new Sundown 1000d the manual says for 1-4 ohm 1 speaker configs to use both positive and then runs a neg line fom the woofer towards the amp... notice i said towards... the positive leands stop on the positive terminals of the amp but the negative lead routes toward the amp and then stops.... Im a newb I know but Id rather ask how then to tell you how I burnt my truck down or fried my brand new amp!! thanks in advance.

What's up everyone! I am starting to learn more and more about systems and tuning them correctly. I have a mtx 421d am with a 8inch American bass sub, I need some help on how to tune the amp and what songs you guys recommend. It hits hard with low bass music but with bands or other k8nda bass it doesn't hit right or it won t hit.

ok i have a 1995 dodge ram single cab and i am buying 8 rockford fosgate 5 1/4 4 in each door a set of rockford fosgate 6.5 components. i want to know what amps i should run these with i would prefer a separate amp for the component set. i am looking to buy from ebay,sonicelectronix,or onlinecarstereo. this is the product code for the speakers i am going to use. Rockford Fosgate P162S-- component set Rockford Fosgate Punch P152C-- speakers

Ok, right now my system is still kinda up in the air, but I know I will either be running a sundown 3k or a RF 4k amp and a little amp or two for mids/highs. The vehicle is the 4.3L V8 F150 (2008). I am pretty sure the stock alt puts out 110 amps. I know I need a couple good batteries for under the hood and in the back. BUT, about what size alt should I look for roughly and what brand. I have a local stinger dealer that sells a 220 amp alt for 700, but not to sure how good that is or not. any input would be great.

Well today at the TBP bass wars event, I found out that I'm not getting any voltage readout off the RCA's from the headunit. Tried it with several meters and it wont register anything, just shows 0.00 .....So apparently, I'm not getting any RCA voltage input to the amplifiers... Someone suggested I needed a line driver to solve this problem. My question being, would this solve the probem....being that I can get a cleaner signal and can adjust it to the voltage I want.. ? Thanks for any help guys, it is very much appreciated........I'm still learning, so please bear with me...

Looking at the audiopipe AQX-3500.1 they are priced great for the power just want to get some feedback on this amp any info experience would be great thanks.

im currently running a Zapco 360.4 brigded 180x2 for my componenets and a Xtant 301a regulated 300w (old school pre MTX) for my sub... huge fan of US made amps, both amps i know for sure are underrated and are badass amps, but im stuck i have an opportunity to pick up 2 audison amps for about 600 bucks... the LXr4.300 and the LXr1.400... i know audison makes great high end amps, but these are their middle end stuff... i was just wondering if it would be worth it to replace my current setup w/ the audisons has anyone tried the LXr line out? thnx for lookin

Ok, heres the deal. I have my Orion 4004 underneath my 2500D and it gets hot. How hot? Very hot. Hot enough to burn your hand. Hot enough to send it into protection after listening to it for 30 minutes. The components are bridged on it at 4 ohms. Many people have told me that it shouldn't be getting this hot. I think tomorrow I'm going to rewire it to only use 2 channels which will suck as far as power goes. I may also try to throw my planet audio vx3002 on it and see if it does the same thing. I have heard some things about orions not liking high input voltage but the gains are set about halfway. One other thing I am having problems with is at higher volumes (30/40) my …

all right, the stereo i want has been out of stock for like 3 months now, and im starting to wonder if it will ever be back in stock. my questions is, i want a flip up screen stereo, what are good brands? and i want cheap ones. if i cant find a cheap one ill just wait. i found some jenson but i dont know if they are a good brand, also fahrenheit is cheap but ive never heard of them. unfortunately alpine doesnt have any, oh i need 3 preouts, front rear and sub.

hello i need amp wt these specs for my jbl gt 4 1000 watt 2 woofers please suggest me a good a amp 125W/2 ohms bridged mono (bridging into 4 ohms). Amp should have 4 channels each rated for 125W/2 ohms.

Ok, redoing my setup in one of my vehicles. Equipment is 1 JL 300/4 and 1 JL 1000/1. Hooked everything up and right off the bat, the low voltage light comes on the JL 1000/1 and the 300/4 won't come on. Checked voltage at amps and I'm getting 12 and both. Now, the only thing I did different from the previous install was I DID use a relay on the remote wire, this time I didn't. The deck is a Pioneer and I'm wondering if the remote wire on Pioneers can't support 2 amp turn-ons. Any one got any suggestions?

Planning a build in a 2012 hyundai sonata with the infinity premium system while retaining the stock unit Here's what we have so far Hybrid audio clarus jl hd 600/4 + 750/1 2 jbl gto 12's(IB) No processing as of yet since the head unit schematic is very tricky. Now, from the information I've gathered The stock head unit has a digital out(spdif) that goes to the factory amp. Usually, you'd go straight from head unit to processor, but, if you bypass the factory jbl amp, you lose bluetooth, xm, & am/fm radio. I'm about 90% sure the speakers crossed inside the amp, so I'm lost on what to do here. Tapping after the amp seems like the only option, but I can't seem to f…

I'm trying to find a very small mono amplifier to power an 8" Kicker CVT at 2 ohms. The chassis itself needs to be very small as I plan to mount it above a wheel well hidden. I'm looking for 200 watts, any ideas guys?
