This is 4 channel sony amp. It drives my Kicker k65's and my K693's. its 75watt rms each channel, and sound quaility is great by my ears.
I used to have a sony 2ch 150rms amp for my old rockford subs, but I ditched it when I got my new subs and a Kicker 600 amp.
btw: I also have the new Sony P5's 12" subs. I was kind of skepitcal at first, being sony's previous crappy subs, but for 2 for 150, I had to get them. lemme tell ya... These things KICK ASS!
I can drive through any parking lot, crank things up and set off car alarms, just like the guy who buys JL W7's.
On the other hand, When I first got the car, I stuck some sony 6x9's in the rear, and within 6 months of having them, running off the deck, at 20watt mind you, they started getting fuzzy and crackled a bit. So i wouldnt recommend their speakers, but their new amps and subs are great.
