k. thanks. i know a but about ca but still don't know a ton. i got a pair of type r comps but i don't have the power to run a second pair plus it would pull my sound back. so just some coaxils would do good. right now i have my stock 6.5s from the front spliced into the rear in some ***** rigged boxes lol. so out of all these the infinities would do best not on a crossover for rear fill? i don't mind the bright highs.
