Alright thanks to helpful advice from this site i got my new speakers. like them so much i ordered a 2nd set for the back. and a new pioneer deck. so what about subs? i heard i would need to get low profile subs, i was wondering if anybody had any good ideas for brands and sizes, i will probably do a double set up with the box under the seat but i might consider doing a single sub if its really worth it. any help is awesome again.
