Speaker swap out/upgrade?s

k went with infinity kappa's front and mid, not much clean bass. So should i put the second set in the hatch (cut insert) and find some good 6 1/2 subs or just leave them, tap the vocals from the rear to it and put a 10" in the rear? Listen to everything but rap, but still like my bass

You'll get even less bass mounting them in the hatch area. And if you are using the factory amp I'm pretty sure that the hatch speakers are high passed (the lows are blocked) because there is only a 4" midrange back there (plus a tweet if it's a Firebird). To get good bass performance the speakers need to be mounted to a rigid surface with a lot of mass. The rear hatch speaker is just mounted to a flimsy piece of plastic. What happens is that most of the bass energy from the larger speaker will just get transferred into the plastic panel. Your best bet would be to leave them in the B-pillars. And if you're using the factory amp replace it as soon as possible.
