Pyramid 2 Channel Car Stereo Amplifier - 5000W High Power 2-Channel Bridgeable Audio Sound Auto Small Speaker Amp Box w/MOSFET, Crossover, Bass Boost Control, Silver Plated RCA Input Output - PB3818

Really great amp for $86.00 Sounds as good as the signal your feeding it. Plus really a lot of good stuff going for it. I have a lot of experience with all kinds of transistor amps and I love the fact that its really just one big aluminum heat sink, those are the only kind I buy. Adjustable hi and low pass filters for front and rear channels and the adjustable bass boost instead of just on and off like some models. Having high and low voltage inputs is definitely a plus, and its very simply bridgeable also, making it very versatile for any application, after market or stock radio. So that means you can always use it the future no matter what system you happen to have at the time. Tuned properly I get very crisp sound, the bass boost gives my rear 6x9s a really cool clear bump and loud enough for 90% of the population. All in all if your on a budget and your stock radio just doesn't cut it. You'll get every pennies worth, you can't beat the value for the price. The only negative thing I have to say is they play with the watt output specs pretty badly, 2000 watts was somebody's dream rating because thats the only place you'll see those numbers! But it seems theres a lot of that going around these days. It only puts out about 35 watts per channel @ 4ohms instead of the 50 they advertise on the box. If you ran it at 15-16 volts probably would hit 50 but who does that in a car, nobody. I bridged it to 2 channels and it blew the factory tweeters in my doors so there is a little power coming out and I noticed it doesn't run super hot like some do. Most stock radios do like 12watts, so you have an idea. So you'll probably need to upgrade your stock speakers to get the good sound out of it. A good rule is this, watts are about a dollar each, you want 400 real watts, cost you about $400 real dollars. :)

Got a lot of BANG from this amp... Bought and installed this bad boy in March... It is September and buddy is still going strong with NO CLIPPING or OVERHEATING...ADVICE: USE 4 gauge or BIGGER For BOTH YOUR POWER and GROUND WIRES... Your amp will burn up trying to push BIG power thru SMALL wires... Don't be scared to stuff those BIG wires into the SMALL space use tape or make a divider that will stay in place to keep the wires from touching... add a 100w fuse and this amp will take care of whatever you give it... Pushing two 12' Boss 1800w per sub/ 900w RMS per sub... only on 1 channel!!! With plenty of power left to play with...ADVICE: DON'T SIMP ON THE SPEAKER WIRE EITHER 12 gauge or bigger will do you good...REMEMBER... BREAK IT IN FIRST...After that you will hardly have any maintenance other than fine tuning it to your liking... Great buy at an even greater price... Get this amp now before the maker realize how good their product is and jack the price way high!!!

Okay I purchased this product knowing full well I was getting what i was paying for, a cheap amp. But if it was even half of what it said it was it would do just fine for me. I have 2 subs, one is a 10" and one is a 12", and they are both DVC 1100watt (400 RMS). At first I wired the subs in parallel and gave both subs their own channel (2 channel amp), as I thought this would get the best result. It did get them going but it wasn't "rattle the car" strong which i know these subs could do. Then I did a little more research and wired the subs in Series, then bridged Both subs together (both sub Neg- to 1st channel Neg-, and both sub pos+. to 2nd channel pos+) and OMG. This Amp is definitely worth the money.All the people that say this thing barely moves their sub.... Didnt hook it up right, simple as that. Do your research, find out the best way to wire your speakers to the kind of amp you have to get the most watts from it, Get the right Gauge Amp kit for your amp, and with this 5K watt amp, a capacitor is needed. if you did it right you will know. The most i have ran the amp in one session was an Hour and it was barley hot, next trip i take i will see how long it takes to over heat.This Amp isn't Fancy and doesn't have a bunch of lights and cool modern looks, But I would trade all that fancyness for a few more watts and a solid amp, which is exactly what this is. Thank you Amazon, TY Pyramid.

So I bought this amp to replace an old kenwood 600w amp that took a crap on me. Now some people are saying this amp sucks and some people are saying it rocks. I am a pretty smart and reasonable 21-year old dude and I would say for the 60 bucks or whatever it cost, it was a very good deal.I would agree with some of the other reviews about how it isn't 2000 watts and that's why I gave it 4 stars. But I figured it wouldn't be 2000 watts and so I wasn't taken by surprise. It does however pack quite the punch. I just have a 10" Alpine Type-R and it is more than enough power for the sub. I keep the gain about 60 percent and it is more than loud enough.I have my system wired up the right way and for those of you that know how to properly wire subs, this amp will stay cool. My setup I believed is wired at 4 ohms and the amp stays cool to the touch even at higher volumes and does not cut out. And I listen to a lot of hardcore music where the bass drums are constantly kicking and the bass drops are heavy.If you're looking for an amp and are really limited on what you can spend, I would definitely recommend this amp.
