Great amp for the price.

So I just amped up my ride with the NVX J800.4 and now I wanted to amp my girlfriends 2013 Nissan rogue. You see she loved her – unit that came with the car so getting an aftermarket head unit wasn't really an option but I wanted her to have an sound upgrade as the stock speakers and stock amp were very weak as with all stock speakers getting 10 W push to them. So as a present yet I had infinity reference speakers put in her doors now and this you got pioneer amp to power them. And I have to say that The end result was fantastic she now has crystal-clear mids highs in more than enough power those infinity 6x9s lower frequency woofer cones thump! No her Nissan rogue sounds better than the one she originally wanted that had the Rockford speaker system built-in and she saved about $9000 purchasing the base audio package Rouge.

Great versatility

I am happy with this amp.its pushing 2 Jo trx 6x9 +a rf p1 12" sub and is doing a surprisingly good job. Gets warm with the heavy load on it so do not over adjust the gain or it will make it very hot with no extra output. Suggest ofc power and ground cables to help the heat and elevate the amp 1" to help airflow. Its helps more than you would think.
Great sq.great amp. Is what I expect from pioneer!

Great Amp!

Pioneer always puts out great products. Running (2) 6-1/2" and (2) 6x9s off this amp. Easy to setup and has great sound quality. I have this playing on my YouTube channel. "Bj Hammon"......I'm wearing a red cap and holding a margarita glass :)
