Pyramid 2 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

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.

Let me start off by saying if you're the type of person that is looking for some good bass to balance out your sound then this is the amp for you it's cheap and will do more than the job.I am using it to power 1 sony xplod 12" sub and it sounds awesome. Now if you're looking for competition like sound then this is not for you so don't buy it and expect it to do that, there are many amps out there that you can look at starting at $90+ but don't expect one at $40 to do that job,in other words don't be cheap and expect top quality,with this amp you won't get what you pay for you'll get more than that because it would be good even if it was $60 but thank God Amazon has good prices. Overall this amp is really good for the price but again don't expect something you know can't be offered for a product at this price,it does push subs without any problems and sounds greats no distortion even when set at high well at least for my setup. Try it out for this price you'll be blown away and surprised how good of a brand pyramid is.

This amp is ideal for those on a budget as stated by a few others here. Its great if you're looking for something to bump for your pleasure! This thing can do what it do! I have 2 kenwoods 12's in a ported vented box and this thing is perfect for it! It rattles all the mirrors with ease. It does get a little warm but maybe cuz I am in Las Vegas and its hot as hell here...lol But you cant go wrong with this amp! I use to have it before in a mitsubishi I hadand it worked great. Back then I found this amp at a swap meet back in Cali. Here on Amazon I seen it again and couldnt pass it uup! I now have it in a Mazda SUV and it works great for me! It gets attention on the block! 2 thumbs up!!!!

I was skeptical at first with some of the negative reviews, but things have been going good so far with this amp for me. First, everything in and out of the amp: This amp is in a converted 1997 Ford Econoline-150, hooked up with a Scosche 1500(or around there)-watt wiring kit from Walmart, outputting through 12-gauge cable to two Rockford Fosgate P1 subs. I have no complaints about this amp. I've been using it for over a year now. At one point recently, I rewired the subs (replaced the terminals in the sub box which were loose at times, and also replaced the wires with better ones from Monoprice), and the red light came on and the one sub I had hooked up at the time stopped. I'm not entirely sure how it happened, but I checked that nothing was contacting anything it wasn't supposed to, and since then it's been working fine again. I can't speak for overheating issues very well....the van this is in is a conversion, and it's mounted between the back seat and wheel well in such a way that it has decent ventilation on both sides, so it doesn't get very hot at all, even in the summer. As I said, I haven't had any problems with the amp itself. The only issue I have is, depending on the wiring kit you use (like the one I did), some of the copper wires for the bigger cords will have to be loose, as the ground wire out and power in spots are quite narrow. Still, it hasn't affected its performance as far as I can tell.

Purchased the amp last week for 44 bucks with free shipping and arrived on the given arrival date as what amazon stated. Installed it yesterday to my technics 4 speaker subwoofer lying around, 2 speakers where both wired in parallel so in all both speakers in right and left input has 8 ohms and total of 16 ohms for all 4 speakers each speakers is rated at 300 watts. I thought this would be an overkill for my amp, upon completing all hookups I fired it up boy it still sounds good played several hours of music amp still stayed cool to touch despite my speaker setup. If you're looking for a decent but cheap amp to fill some low end bass that your current setup lacks then is right for you but if you are looking for some pounding and rattling bass you might spend more on high end amp. Update: Have the unit for almost 5 months now without any neg issues. Just a sort of advice when installing this unit is don't cheap on the connection. Every connection you do must be soldered with the amp kit you're using. Solder with the wire connectors from the battery to its fuse holder, ground wire and towards the amp itself. Tighten the connections properly and remember to have some good grounding point by sanding into bare metal where you tap your ground wire(grounding wire must not be more than 2 feet length), it saves some headache in the future we're talking high current flow here so any loose and on and off contacts can cause short circuits it can either damage your amp or some electronic components in your car. Lastly the casing of this amp has some hole or perforation at the bottom which helps dissipates heat so don't block it leave a little clearance there by putting some washers/small bolts or any alternative materials you have in hand for elevation so that when you screw the amp to the surface it will not just lay flat obstructing those openings which helps in keeping the amp cool.

Why do these people have to lie to sell amplifiers , right when you open the box there is a paper on top says "Warning not 2 ohm stable" shows speaker hook up wrong way and right way I would not of even purchased it at all if I would of known that then there is the watt issue when are they going to regulate the specs on amplifiers like class D Drivers side is louder than passenger thought my indoor speakers came unhooked took door panel off and checked could hardly hear sound so I switched RCA's L with R passenger was louder then and like most amps there is no R & L balance on the amp They need to have a 0 (zero) star for products like this, trying to sell with no luck

I was really skeptical about getting this amp as a lot of other people probably were too. The $40 price tag and 50 watt output led me to believe this was gunna be a crappy amp but at the same time i didnt want to spend a lot of $ just to power some barley average 10in subs. Honestly after hooking it up im impressed. This thing is not weak at all, my 10's were pounding hard as hell. Prior to this i had a Crunch 1000 watt amp and honestly i cant tell the difference in performance (except that the Crunch cost $90). I let the volume blast for about 30min and after touching the amp it was barley hot. I think you'd be hard pressed to find a better amp for $43. *EDIT* So i decided to changed the overall rating from 5 stars to 3 after using this amp for about 2 months. As far as the power goes its still the same, makes my subs hit hard nothing to complain about there. The only problem is that this amp seems to get hot and shut down pretty easily. It wasnt that hot outside when i first reviewed this amp but now that the weather has been getting a lot warmer the amp is going into protect mode after about 10min of use. I must admit the ventilation isnt that great in my trunk but i've had quite a few other amps that never shut off despite it being very hot. Overall its still not a bad amp espically considering the price but the fact that its hard to use it when its hot is annoying for me.

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.

Insanely overpowered amplifier, supports very high frequencies too.

Bon rapport qualité prix
