The Kickers are Comp VR's, and they're dual voice coils. I bought them in 2001, and I assume they were 2001 or 2000 year models. I don't know what ohm load they are wired in my car. My original setup was done by a shop, and then I switched the box to my Civic. A few years back, the box got water damaged, and I got a new sealed box for them, so they have a relatively new box (2007 purchased).
I am thinking maybe I can run the T3's on my Civic and bump my Kicker CVR's to the Camaro, but I really like the flexibility of the Infinity's. Also, my buddy just bought a complete JL Audio system for his ride, and has a COMPLETE set of HiFonics (2 amp, sub, etc) that his buddy who owns a shop is holding, so I'm going to head over there and talk to him about stuff.
I don't know how good of a system HiFonics is, that's why I'm hesitating on that option, and wanted to do some research. His car hit though, but he has an older Camaro, which was hatchback. My Camaro is the newer one, and my subs will be in the trunk. I don't know how much of a difference this makes.
