Depends totally on the speaker location size and the $$$ you're willing to fork out. Tell us that and we can help you more. Thunderforms work well, I'm personally not a huge fan of their subs, but if you like them that's what matters. Not to mention you're really paying for the box, not the quality of the sub used as it's their lower end model.
Exactly. I have a dinking little cab that I want to get some good sound in. Sub, amp and upper end compentent speakers and maybe some door dampening panels, maybe spend around $1500. not including HU? Does that sound reasonable?
