Howdy y'all. I just got a new vehicle, and I need some suggestions on what to do. Now, I kept my head unit (JVC KD-AVX2) from my old truck and my subs are on order already (MTX Thunder 5500 x2). But, I still need suggestions as to the amps for my subs and speakers and what speakers to get. So here's what I need:

pair of 6.5 in. components and 5.25 coaxials speakers
600 watt monoblock amp
4-channel for my speakers

Now, i work at a certain Canadian retailer and get Exile, MTX and Infinity stuff at a pretty decent discount, so those are the brands I'm looking at primarily. It would be a huge help to hear some outside opinions.
