I currently only have an older 12" Alpine Type R sub running on a 2channel Pioneer amp. Looking to replace stock comps up front. Have looked at CDTs and Focals just need some opinions/advice. I will run them off the pioneer amp and get a mono amp for the sub which will be replaced later. I can get 125x2 4ohm or 190x2 2ohm. Only looking to spend 100-150 for the comps.
