Precision Power i1000.4 650W Class D Full Range 4ch Amplifier,Black & Copper

I love this amp. PPI is a great product.. Amp is very small and packs a ton of power. I'm impressed.. Thank you

Excellent amp that is easy to install and will fit anywhere. This is my third one and I have used them for marine installation, jeep and now my truck. The bridgeable function makes them perfect with more power than your speakers can handle. Price vs product is exceptional. I highly recommend

Well after the seller finally sent the amp i recieved a damaged box. Completely torn open and seal broken. So the 2 day garentee turned up a week + later. But the review is for tht product and not the dummies shipping it. I got the amp. Its small. I had my doubts but i did my research and had high hopes. Im using this to run 6- 6x9s and 2 6x8s. Each channel is powering 2-4ohm speakers for a 2 ohm load. So each speaker is getting about 150 watts. I needed it loud for when were cruising in the boat. You loose alot of sound out there. I will not have any issues anymore. Yes i have the amp gain prety much maxed. My cross over is at 80% "gain". So im maxing out the amp. Its not even running that hot. Yes its warm but not hot. 0 gage wire for both power and ground to a distro block into 4 gauge. Running nice. For a lower end set up this thing sounds great. Ill update if something changes. First weekend out.

Amp is pushing every bit of the 140w/ channel its rated for. My only issue was one of the screws to connect the speaker wires stripped the first time tightening it down. Other than that, build quality is good, and it sends out nice clean power to the speakers. I'm more concerned with sound quality than rattling the windows, and this unit delivers!

Esta llego a tiempo y no se a podido instalar por falta de la pantalla. Gracias

This must be made by Precision No Power. Dead on arrival. If you are looking for an amp that actually works, pass this one up.

Gone are the days of giant amps that takes up half of your trunk. I installed this and it works. I don't have any equipment to test the efficiency, but if you google (video) dynos of other iON series amps, they perform very well. I will infer that this amp, although no dyno results, perform equally as well. The fuse is on the bottom side of the amp, behind a clear plastic sticker. You have to peel the sticker, use needlenose pliers, replace, then reaffix the clear plastic sticker. Pros: Price and Size Cons: Fuse is hard to replace (requires needle nose pliers and a steady hand)

I opened it. Very clean design that lends itself to ruggedness. I would definitely buy another. Its hard to justify buying the smaller versions because the "Watts/Dollar" is outstanding. After it got hot, the name badge glue softened and it fell off. Doesn't bother me though because the amp PERFORMS.

Sounds pretty bad. There seems to be a major boost in the mids. Definitely not a sound quality amp.
