This is a very big amp that will require a lot of space to mount-forget about under the seat mounting. It has adequate power for the satelites, but the sub section could use more power in the 4 ohm application. It runs evenly but I don't get the effects of great headroom. I am using Infinty refernce speakers which are not the best but I have not yet played with the crossver points. I am using a Bazooka 10 inch sub which is not really putting out rock solid bass wiht this amp. I plan to exchange that with a JL 10 inch and hope the amp has the power to rock that, but I think I will have to trun up the gain and bass booth for that.
This amp has everything you need to upgrade from a factory system. To Neils From Gaithersburg, Maryland: of course 150watts to your sub is probably not enough power to match your speakers. This amp was meant to be hooked to a sub/subs at 2ohms, to get the full 300 watts out of it. Heck, you can even buy some Infinity Kappa speakers (2ohm impedance) to sqeeze out even more juice. My friend had this amp before he rebuilt his system. For the money, you can't do any better.
