Plenty of power; I used it to pust 2 JL Audio 12W0's and it had no problem, in fact it blew one! Now I'm using it to push 2 sets of components and it does just fine. Also it looks great, and has a great crossover system too.

None; this amp has everything I want.

I bought mine off a friend for $150.00 and you can easily find one for this price on ebay. If you want a clean amp that is priced well with plenty of power buy a PPI Power Class series.

POWER TO SPARE, STYLISH, EFFICIENT, Q BASS PLUS IS GREAT

CROSSOVER COULD BE MORE FLEXIBLE

PAID 650 NEW FOR PPI PC4100 AND WAS NOT LET DOWN BY THE POWER, BUT JUST DISSAPPOINTED IN THE CROSSOVER SECTION. OVERALL, VERY PLEASED. I LOVE THE Q BASS PLUSS ALLOWING ME TO ADJUST THE BOOST, FREQUENCY, AND Q OF THE THE BASS. JUST NOT VERY FLEXIBLE. ONLY SOLD TO GO TO A 6 CHANNEL AMP SO I HAVE A SEPARATE CHANNEL FOR MIDBASS UP FRONT.

clean, looks good, sounds good, plenty of power

The PPI PC275 is an outstanding amp for highs. I have tried several amps on my Focal highs including a Punch 200x^2, and the PPI had the cleanest sound and the flattest response. The 275 is also a good amp to run subs if you are interested in clean music with some kick--not SPL.

very clean and very strong. Pay at least a $1 a watt and it there to prove it.

Gets hot. wished it went to a 1ohm stable. But, on the other hand they put out so much power that you would not need to go to a 1 ohm.

I have the Art series A404 which is a 4 x 50. I have had this amp for about 5 years now. It is on my highs at the moment and i love it. Very VERY clean amp. I remember going to an audio store and saw a product review magazine. It covered everything and listed top five audio equipment with no price range. PPI amps was in every division. They were not first in every division but to be in the top five in Every division showed me something. I heard before i bought one that they were some of the best product on the market and was in every car install magazine i pick up. So i said screw it, and got one. And it is about 6 years old now and no problems. I just got my hands on a A600.2 art series. This is pushing about 850 watts. A ppi authorized tech. worked on it once cause it blew, so they installed a new board but did not have the original parts so they had to install a different board. So they put in a bigger board. so instead of 600 watts it pushes close to 1000 WATTS!!! Oh yeah! I have it turned down to about half way on a Flat piston 12" PPi woofer in a box that PPI told me to build. Talk to them regularly.
I reccomend this brand to anyone. Some of my friends have them and love them. Others Wished they did.

The best amp I have ever had!! I say that next to sound streams Tarantula this is the best amp for the money!! I have pounded this amp on 4 kicker 8 ohm compitition 12's for a db of 162. but its been four years and those woofers are dead now actually i've went through 6 of them. now i'm running 3 12in square kicker solo's 4 ohm paralleled. XPL is 164db in center of car. This amp is still winning me trophies. This amp is rated @ 2x350 in 4 ohms 2X700 in 2ohms and 1400X 1 in 2 ohms. But guess what I've tested my outputs and mine does run at 1 ohm and pushes out a whopping 1050 x 2 RMS. Almost full powering my 3 12's and it is clean cuase it has a built in 24 db peroctive.

There really isn't one but I will go with this. I wish instead of fan cooled I wish it was liquid cooled like the series before it the art series.

I just can't say enough for this amp i have pushed it with the following speakers mtx-kicker comp's-kicker XPL's-JL's-and now 3 kicker square 12 solo baric's. and its made them all sound pricesless.

Sound quality
Plenty of power to drive anything you throw at it.

Not very versatile. Only two sets of RCA. No Sub input.

I have had this amp for approx one year now. It's a six channel 6*50 RMS at 4ohm bridged 3* 200RMS (4 ohm) double at 2 ohm stereo. I'm powering 4 Alpine DDD drive speakers 2* 6 inch split and 2 * 6*9's plus one 10 inch Alpine ZR 254D sealed box sub. The head unit reference series Clarion. If you could still buys these amps, or the new Power class series in Australia I would go out and buy another tomorrow. The sound quality is incredible. it can be a little harsh across the higher frequencies at times, but this is something that probably could be solved with slightly higher quality speakers. The clarity and power is incredible, it is definately (eventhough I haven't actually measured the power yet) underated power wise, and it drives the Alpine 10inch effortlessly (the sub is rated at 300 RMS 1000W peak). It says 3* 200W bridged in the manual but this definately understated. The finish is excellent (chrome)and for those who like it loud it can go bloody loud. Loud - personally not my thing prefer sound quality, and in this area the PC6600 at that price range (without going to extreme high grade audio) beats anything else I ever used hands down.

This amp is awesome. I seriously belive that I take it for granted. It is clean and loud. It is being used with a Pioneer DEH-7200 deck and an MTX 10 inch sub. Jealousy spreads wherever my car goes. Most people cannot get the sub/amp combo to blend in naturally with the fronts and rears. PPI solves the problem.
