Well I had 2 kicker comp 10" subs and one of them just died. I started to look for new subs and so far I found 2 12's of the same sub at $150 and I loved these but then I started to look at 1 15". I've been looking at a alpine type r dual voice coil. I have this amp http://www.crutchfield.com/p_113XXV03A/Kenwood-25th-Anniversary-XXV-03A.html?tp=115 and it works pretty well honestly. As for what music I listen to I honestly listen to everything. Rap, rock, country, ect ect. I thought about 2 12's and honestly they are all expensive for the ones I'd want. I'm looking to spend about $200. Whats the best sub for the job?
