For me I went with a nvx jad800.4 amp (class d so runs a bit cooler than class a/b), component speakers and an alpine 8" sub. The amp is small enough to fit underneath the seat without any problem. IMO you only need front speakers and get some good ones.

I'm currently working on making the kick panels and sub box but i wired everything out just to test it out and it sounds good to me. More than enough in the small cabin and loud enough to hear over the engine.
