I'm putting a new system in my daughter's first vehicle, it's a 2001 Toyota 4runner and I wanted to go with a 12" sub that is more SQ than SPL. I've looked at Image Dynamics IDQ series, PSI platform 1, and FI level 1 I think it is, and Rockford Fosgate Punch P3. I'll be using a ported box to whatever specs needed and tuned as required. My price range is about $250 which keeps in my budget for the entire system. I'll be powering it an NVX 1100.5 having 650 rms at 2 ohms to the sub. Please let me know your suggestions and thoughts. I'm up to other brands if better recommend. The goal is to have the musical first since she listens to all types, but would also like it to thump pretty hard for the deeper stuff.
