Precision Power PPI S850.1D

Excellent Amp, Price, and Performance

I purchased this amp about a month ago. I installed myself and it's hooked to an older RF T1 Dual 4ohm sub (equivalent to the current RF model P3D4-12) and wired into a 2ohm load. I built my own 2.25 cu ft vented box. Man does it pound! It's in an Accord and I've never had anything perform better! I'm the kind of guy that always seems to push the limits of my equipment. For the first time in 15+ years I have an amp that I don't have to turn up all the way. With the bass knob set at 1/4 to 1/2 I can be heard up to a half mile away! I LOVE this amp!

Great Amplifier. Recommended.

Pros:
-High RMS power rating.
-1-Ohm stable.
-Runs cool to the touch, luke-warm when pushed hard.
-Relatively small footprint.
-Remote level control w/cable included! Yay!

amazing for the money!

This amp is a great little amp!! Powers my sub with full potential and is cool to the touch!

Great Amp

Bought this amp a couple months ago.
I installed it myself.
I use it to run 1 JL 13tw5-3

It is enough power for my purposes, but I don't think it pushes my sub to its limits.

Great amp for the price though!

Great Amp for the Price

Just bought this amp, and so far am loving it. Have it hooked up to an RE Audio SEX 15 at 2 ohms running in a 2 cubic ft sealed enclosure, and it pounds.

Definitely impressed.

Bought it for the fact that it had the speaker level inputs and remote volume knob to integrate with the factory stereo in my wifes SUV (she is not into car audio at all...)

Was the perfect compromise for us (satisfied my obsession while not breaking the budget)

Don't let the off brand throw you off!

I was very scepticial about buying this amp for it being a class d mono block. After hearing good and bad things about them I went ahead and ordered it to power 2 12" kicker CVRs and let me just say that it supplies more then enough power to handle the 2 subs just fine and the extra bass knob really is handy for adjusting the subs amps output. It has gave me no problems at all and has never even over heated. The only small downside is that the amp does not receive the high frequency bass tones as well as normal mono blocks or 2 channel amps. Overall very satisfied!

beast of an amp

This amp is the beast of all amps. I've owned a lot of amps and this is the greatest. Pushes my JL Audio w12 perfect, great sound does not get hot, just a little warm. If you are looking for a great amp at a low buget this is the one that out performs all others.

Budget Amp

I've owned this amp for two different sets of subwoofer setups. The previous was for 2 12" Kicker CVRs wired at 2 ohms. I had that when I barely knew anything about a system. I gave that amp hell for an entire year, and it never quit. I even mixed up the ground wire and power wire once and turned the car on (blowing the inline fuse). It was still a trooper.
Now I have a single 12" Kicker L7. I have it wired down to 1 ohm. I had the sub lying around, and decided I wanted a cheap amp to throw on it. So I decided to go with this. And it'll definitely push it. I have the L7 in a ported ground shaker box, and it'll slap. I have a 4 door Tahoe so there's a lot of air it has to push. I tuned the amp with a digital multimeter, and I believe it can put out more than 850 watts RMS @ 1 ohm. It does get warm to the touch, but I also don't have it where it can optimally ventilate. The most I've ever played is about 2 hours straight at 3/4 of the max I tuned to.

PROS: Solid amp for the money. If you're on a tight budget, this is the amp for you. Does at least its rated amount. Nice exterior design.
CONS: A bit larger than I'd like it to be. It does get a bit warm, so just make sure it can ventilate a little.

great budget amp - does rated power

got this hooked up to a Alpine S 15" at and it PUMPS. Measured 34.6V into 2 ohm with no clipping, thats a true 600W at 2 Ohm

Decent Amp

This amp has been working for years on 2 Rockford 15" subs. It sounds good and puts out enough power, as rated. It does get kind of hot, is the only downside.
