good amp

I would recommend this amp for anyone just getting into the car audio scene. I have this and one 12" memphis audio sub and it makes my chest vibrate (and i drive a volvo 850 wagon!!!) It has never overheated but then again ive only had it for a month and its winter lol. Definitely worth the 70$(i bought mine for 120 from a stereo shop and it pisses me off. I wish i had came here first.

GOOD AMP

Well i was dumb and got this to power two kicker 15s. It actually did ok maybe pushed them about a quarter of that they should. Never overheated or anything. I'm guessing it puts out around 200 rms at 4 ohms.
