This is my first post on this site. I'm not sure if this is the right place to post questions so let me know. I just picked up a trailblazer and have started to install a new system. I have already replaced the head unit, 4 door speakers, mounted an amp and a cap to the single rear seat and installed my two 10's. My question is where is a suitable spot to mount another 4ch amp? I dont want to mount anything on the other side of the back seats. Is the compartment in the floor ok? will the amp over heat without air circulation?
