Hello. I need help selecting an amp for a Cerwin Vega 12" Stoker. My budget is $500. I had my eyes set on a Hifonics XXV- Colossus. Supposedly it's rated 1x3200@ 2-Ohms, which sounds like more than enough to power a stroker efficiently, but after some reading in this forum, the brand now sounds like borderline garbage. I also hear that this speaker requires a very large custom box, or is that also a myth? I have a 99 Crown Vic, so space is no object. Is there anyone here that builds them, or online? If not can anyone help me with specs to take to a local audio shop? Any help would be greatly appreciated, thanks.
