PPI P900.4 Big power little package

This amp is small and does a great job, it has plenty of power for most car systems and stays cool. I cant say anything bad about it. Have a good set of speakers because this amp has got big power!! I am running 2 set of Polk mm6501 off this amp and it sounds very good!!
For the price you cant go wrong, this is a deal..

Simply can't be beat! A steal for the price.

If you want an inexpensive, powerful amp that is very well suited to SQ applications, look no further than this puppy. Gobs and gobs of really clean power, and stays cool even in tight spaces, and its so small! The built in crossovers are also a very nice feature, giving one the ability to go active without needing an expensive DSP.

It's cleaner sounding and puts out just as much power (and 150W more bridged, infact) as my dad's Alpine PDX-F6, all at a quarter of the price! I've had it for just over 6 months and have had no issues whatsoever with the amp. I have it running in 3 channel mode currently, hooked up to Morel Tempo 6 components for my front stage and bridged on the rear for my 15" JBL GTO sub in IB, with the source all coming from my DEH-80PRS. Godly sound. Planning on purchasing another Phantom amp soon, the P1000.1 (from Sonic of course, even being in Canada, they're still the cheapest around, not to mention the great customer service) for my sub and then going fully active with my front stage.

seems great to me!

using this amp at half the rated power and it sounds great. doesnt get hot. would love to hear the potential at the full 140 rms but my speakers only handle 70. reasonably small amp, and connections are all tight and clean. comes with a 0 gauge adaptor for some reason but i guess the more power the merrier. pretty dang cheap too! only had it for a month, but so far its money well spent.

Excellent Amp

I purchased this to power two wetsounds Pro80 speakers on my wakeboard tower. I run it bridged & it delivers! Loud clear power. I ended up purchasing the p600.2 & p900.5 as well to run the rest of my system & proudly boast one of the loudest systems at the lake. Requires less power than conventional amps & they take up half the space. Very happy, I tell you buy this amp, mine came with free foam peanuts.

Clear and powerful in a small package.

I recently installed this amplifier and it certainly has more power than I need for my system. Very clear and loud. no distortion or interference. It has versatility in installation being 2ohm stable. The documentation could be much better. Use a small philips screwdriver and you will have no problems installing the speaker and power wires. Don't forget to buy the 8ga inline fuse, for install.

Good things come in small packages

I got this amp to go active in my SQ install. Being a PPI fan for many years I had to try this one. I was not disappointed. It has plenty of power and is very clean sounding. I have this installed along with my older PPI's and it is right at home. In the SQ circle this amp is quickly growing in popularity.

best amp for $$ period

Runs cool and has gobs of power. I have it running a pair of 8" fosgates and a pair of 6X9 Infinities in my Nautique. It flat out pounds. I would recommend this amp / speaker combo every time.

Great value, power and size

Great value, power and size. Almost too powerful, had to turn the gain way down.

disappointed

i was disappointed with this amp. it worked and performed as expected, but the design of the amp is flawed. as some reviews stated, two Phillips screws on the speaker/power/ground terminals are difficult to tighten with a screw driver and the Phillips heads are easy to get rounded and as a result you cannot get a good contact with the wires .(power/ground/speakers) i contacted precision power via email to see if i can purchase the terminal screws but i did not get a reply and its been about 3 weeks now. because of this i'm giving this product 1 star.

Amazing Amp!

I had all the common worries that we all have when buying amps, Does it have ignition/alternator whine issues?, will it cut out up high or can it really handle high loads?. i upgraded to this amp from the Infinity Kappa 4 and considering they are both within the same rms range, this amp is so much better, brought this thing worrying it was not going to deliver, but once i installed it, boy did it deliver simply amazing amp! i have it powering infinity Kappa Perfects and the sound quality is unsurpassed, everyone loves my system! Would recommend this amp!
