Precision Power PPI A900.1

Deceiving power

This amp is no joke, I have no doubt that this amp is pushing 400-450watts RMS at 2Ohm

I have this little guy pushing a Dayton Audio RSS265HO-44 10" at 2 Ohms in a sealed box and its seriously blowing me away how good these sound together.

For comparison, My previous setup was a Rockford P2D2-12 and the PBR300x1 running in a sealed box. This combo was really nice but the 12" was too big and I needed more trunk space.

The rockford set up did hit a bit harder around 45hz but it never dug as deep or was as clean as this little PPI and dayton combo. Its just so clean!!! It goes down to 25-30hz with meaning. No single speaker amp combo I've ever heard could be so clean down low (especially not a single 10"). This tiny Amp just pumps out the clean watts to do so. Im seriously impressed...

This set up sounds better, hits harder and goes lower than my old 90s PPI and Rockford 12s set up. I'm still trying to wrap my head around this...

a few small cons:

The remote is nice to have but is so touchy it really only has 3 modes. almost off, on and "what is the rest of this dial for?" only about 10 degrees out of the 280 is usable. So to go into more detail, if the dial is all the way down to the first notch (see the pics) the amp is not completely off but its close. Then move to the 2nd notch and its pretty much at full volume. Then somewhere between the 2nd & 3rd notch it stops adjusting the volume. This isn't the clicky kind of knob so if you have sergeon, dextrous like fingers you can probably find a small place between the 1st and 3rd notch to suit your genre but its not easy to do. let alone in a moving car. Ive tried adjusting the Gain on the amp for over 2 hours and found this had no effect on the remotes adjustability what so ever. it just is what it is. So when going to adjust your gain on the amp: turn the remote up to 2.5-3 notches. Then trim your Gain on the amp.

The power block has 5 leads. 2 for power, 2 for ground and one for remote. so you either need to run a distribution block off both your power and ground wires or you need to get creative. I actually just soldered 2 smaller 12G wires to my 10G power and ground, then heat shrinked them and then shoved them into separate conduits.

Same setup goes for the speaker leads but since im running a Dual voice coil Sub it worked to my favor.

Bottom line, if you need a small amp with serious, clean power. Get this! Its cheaper than the Rockford PBR300x1 and easily out powers it too.

Great little sub amp!

I lost my Rockford PBX300.1 to a failed alternator. Yes, that is a problem to be aware of with that amp. If your voltage drops while running music, it lets out major smoke. I purchased this amp to replace that amp. This amp is more powerful, and costs less. This amp has more features, too. The subsonic filter is a must have for people with a ported / vented enclosure. This little wonder hits HARD! I have it running 2 ohms to a DVC 6" Bazooka in my F150 King Ranch. It did not hit with the Rockford like it does now with the Atom. The remote bass boost knob is peculiar. There is a bass boost adjustment on the amp, which gets bypassed when the remote knob is connected. Strange, but true, the remote knob degrades the sound. Additionally, the adjustment is not linear. There is a point about 40% and up that makes almost no change to the output. Like I said, strange. If you can live without the remote knob, do it. Lastly, the power connection is odd as well. There are two 12V+ and two 12V- connections to make. 12 gauge wire maximum to each. I cheated a bit and put a 10 gauge in a forked spade connector, trimmed it a bit, and got into each terminal safely and without running more wire or splicing. Overall, pleased to find this little Atom bomb of an amp.
