I'm getting one infinity kappa perfect 10 for my high bass and I wanted to get the infinity kappa perfect 12 for my mids what sub would go good with this set up to give me the low bass and what amp would be best to make my idea work. Thanks
Sounds like you're looking for a decent SQ 12" IMO. Don't do the 3 sub approach to supply all the range you're looking for. That has bad written all over it. A decent single driver paired with your components will do the job much more efficiently.
hell, i had the infinity perfects.. i thought they sounded great, just get 2 12's with nice custom ported boxes and you should be all set with what ur looking for.
