looking for amp suggestions

I have a 05 F150 crew cab (4 door) that I've just replaced the head unit and speakers in and am ready for more power. I used a JVC XR810 HU, Infinity 680.9cs components front door, and 682.9cf coaxial rear door. I'm looking for a decent four channel amp that sounds good and is reliable.

I'd also like to know the best place to mount it. I'm thinking under a front seat, leaving the area under the back seat free in case I want to add a sub later. I do have bucket seats with a large center console that has alot of room inside, more than enough for a amp, but I'm concerned with air circulation. Thought maybe some would have some thoughts on that.

I think I've figured out that you love Soundstream... Haha. Seems like you're constantly recommending them. Might have to look into them a bit more and see what all the fuss is about.

I looked at the Kappa, looks like a good amp but if I put it under a front seat I won't be able to access the controls. I also looked at the Oxygen but there website looks a little cheesy, kinda Chinese if you know what I mean. The specs don't look all that bad though. I'll have to check out the soundstream.

I 'd rather go with a name thats been around a while that others have had good luck with.

So what is a exceptable way to mount a amp under a seat? Where is a good place to attach the ground wire?

I'm going to have to raise the amp up some to clear a a/c vent.

Sorry about the noob questions but the last time I put a amp in a auto was in 1978 and back then I just put it in the glove box using wire nuts to make connections.
