Pyramid2 Channel Car Stereo Amplifier - 1000W Dual Channel Bridgeable High Power MOSFET Audio Sound Auto Small Speaker Amp Box w/ Crossover, Variable Gain Control, RCA IN/OUT, LED Indicators PB717X

This review will come in two parts. First off i haven't installed it yet. But i have used this amp before. A Friend purchased it for a black Friday deal and we beat the hell out of it. We hooked it up to computer power supplies and had it drive a 15" and a 12" sub for hours on end (in two different configurations. one with each sub on a separate channel and another with the 15" bridged) as well as putting it in two different cars (mustang and cavalier) testing both channels and bridged. in the mustang it was hooked to two 12" cadence z series wired to 4 ohms and played off only one channel. In the cavalier it was wired to a single Pyle 15" blue wave sub (also 4 ohm). this amp has endured use in climates all the way from the -20 degree of northern NY to the 85-90 degree of the rest of the state on 3-5 hour road trips. used for about 8 months.As people have mentioned in other reviews, obviously its not a 1000W amp. if you seriously thought that's what you were getting for $40 then you have no business dealing with car audio. However, if you are intelligent and purchase this product with that in mind, then this is a great budget amp. and for me that's what it is. i just needed an amp to use a for a while so i can save up and find a better amp eventually. Having used this amp before i knew how loud it really was. My friend has a 800 W Sony X plod amp hooked to MTX jackhammers and its much louder than this amp. but this amp does hold its own. This is not a competition amp. This is not going to give you earth shattering bass. But if you tune it right and hook it to decent subs then you will have a respectable sound system.If you want a sound system that will crack windshields and be heard 3 blocks away then you'll probably want something else.This being said, having torture tested the amp as much as we did, i decided to buy one for myself. i'll have an update when i actually install my own.

I hooked this up to my moped battery before installing right to the mp3 player with the y cord ,I can hook it up a few different ways ,its going in 1995 Camaro z28, I bridged it ,for them both about half way is perfect,for the price you can tweek it ,it was shakeing the house ,for 37.00 was like new out of box,hooked up to the phlb pyle 12s with 2 tweeters both 500 watts each,its slams the bass,just like the guys said,an I figure those with the less then 5 stars had one that did not work right did not bridge it or turn up the bass levals ,its louder then I would need most of the time ,an could get me a ticket I will be careful,i may just install a marine battery in trunk an eliminate the head unit ,will be easy 10 minutes install,but with time I will hook it up to the head.2000 songs is a lot of music,iwas playing with thse little ones that just did not have the power I needed ,I would say its definatly putting out 500 watts an about 400watts ,is a clean sound its got great sound now I can hear what i was missing,i did not know if I could hook the mp3 directly to it ,guys you can ,I can only imagine in the car how loud it will be,i got 2 mini fans for heat going to make it look pretty like the tank I have in back ,its all about how it looks,when I first hooked it up ,iwas like wow its no better ,then I relized the review I read about bridgeing it to one channel,an that's whear the power is at ,I cant say enough about the amp ,after trying 600 watt an a 300 watt,this is the one ,wish it was black ,but white does not reflect as much heat an it has plenty of venting,i willtry to remember to post pics when its set up in car next month ,make sure you get 1000 watt wire kit ,

I bought this amp on sale during the Black Friday week. I picked it up for $35 with free shipping. My brother in law also purchased one. It's been 3 months now and mine is still pushing my 10" pioneer hard as hell in my '69 Baja Bug. My brother was pushing (2) 10" rockford fosgate subs off this one amp. And for a long time they hit hard. Just recently his amp stopped working. The LED lights still function, but no sound. He went on to purchase a Pioneer amp from WallyWorld, but the amp is going to be pulled apart to find what failed and to see if it is repairable. The problem is he bought a 1000W MAX amp to push sub(s) that have a MAX of around the same EACH. So roughly trying to push 2000W MAX subs with a 1000W MAX amp. This is a bad scenerio. This is overworking the amp, and it is the amp that should over power the subs, not the other way around. But, from my personal experience it has been more than I expected for the price. I paid more for my 400W Dual amp from WallyWorld. I have the bass boost at +12 and the gain at about 1/2 way with a bridged connection to my 10" sub. Since the amp and sub have comparable MAX watts, they seem to work together fairly well (so far). The Dual 400W vs this amp is night and day. The Dual amp pushed the Pioneer sub, but once I hooked up this Pyramid amp it beats the crap out of it! I'm very happy with my purchase, and would recommend to anyone looking for a low priced decent quality amp, and I would personally buy again. Just make sure (with any brand) that you properly set up your sound system. You can run 3 10" subs off a Dual 400W amp, it won't hit hard and will work the crap out of the amp. The amp will eventually die. So if keep this in mind when purchasing. If buying for more than one sub, get a 2000W+ amp.
