I know the insignia door speakers are not that good. your numbers aren't bad because the amp matches the sub ratings, but you should stay away from Insignia IMO. For a decent setup you should dump a little of your money on top of that to get something like rockford. I know ours had some stuff on clearance a while back, like 2 12" P1's with a box for 200-300 bucks. Find a deal like that and go for it.
