I'm looking at a few different subs. I'm looking at the Eclipse SW7124DVC-T2. The Alpine SW7124DVC-T2. And the Rockford Fosgate P312D2. What's your guy's opinion on this? Or should I go a different way? I want some boom in my trunk, but at a decent price (approx $250). I have a ported 12" box already, so I just need a new sub. I'm also looking into an amp and capacitor. Any ideas on that? I really like the Rockford amps. Thanks guys!
