PPI PC740.5

Great sound quality amp. Perfect for a 5-channel setup with full range music. The amp can separate highs(ch1&2), mids(ch3&4), and lows(ch5&6) for frequency specific ranges. To the best of my knowledge, no other Sonic Electronix 5-channel amp offers this feature.

If you want great music quality inside your car? This amp is for you.
If you want to be the center of attention with booming bass without the sound quality on your highs and mids? Purchase a different amp.

High quality

Great amp. Nice clean power to mids and highs. Running ppi 12.4 sub and is really nice. Buy now before the price goes up. The only con this amp has is it gets hot. I mounted mine were lots of air is available for circulation. I installed in a ford transit and the lights do not dim one bit when bass hits. Old school is awesome!

wow power class is back

Back in the day have a few power class amp from ppi. I thought they're great amps. After reading some reviews I thought I would try one of the new ones. I can say I'm not let down at all. I would say this has be the cleanest amp I have herd. I am running all five channels at 4 ohms. The amp gets warm not hot. The sq does not degrade. I would say ppi is back making great amp for the people that know sq means the most.

excellent sound

I purchased the ppi power series 740.5 instead of using the alpine 4 channel i have and purchasing a separate mono amp. For what I have it works wonderful it is powering JL cs2- 650 components in the front, JL 6.5 2 ways in the rear and a JL 8" sub in the trunk....great power to all, and if you think a JL 8 is too small, power it with 250 rms watts and tell me so.

Amazing sound quality and plenty of power

I owned a PPI PC series amp that lasted 11 years and planned to go with another one. However, reading that the company had been bought out and was no longer the same had me skeptical. I almost went with Rockford but I’m so happy I choose to try a new PC series amp from PPI. This thing puts out 100% clean crystal clear sound just like the days of old! I couldn’t believe the musical detail I was hearing from digital (MP3) music. I have the Fosgate Power series components and I’m running channels 1+2 to the tweeters and channels 2+3 to the mids. Channel 5 sends 380 watts to 2 JL Audio 10W1’s. The JL’s used to be powered by a JL Audio E1200 and there is no comparison. I’m also glad I’m running the mids and tweets off separate channels. It makes a big difference having separate gain controls to send more power to the mids so the tweets don’t get too hot.
