I just hooked up a new Rockford Fosgate Punch Power 800.2 amp in my Dodge Dakota Extended Cab R/T. I got 4 gauge running to a 1 Farad capacitor too. The head unit is the Panasonic CQ-DFX701U. Anyways....I have 2 12inch Infinity Perfect subs (4ohm) in a sealed box with about 1.25 cubic feet for each sub. I had the amp running one channel (it's a 2 channel amp) to each speaker. But I looked on RF's website and it showed how to bridge it to one channel for 2 speakers. So I just bridged the amp so I think that the amp is running at 2 ohms now. <br />Is that too much power for these Infinity speakers????<br />AND should I get a smaller box for the subs or a bigger one for Infinity Perfect subs??? I would like a smaller box, because it takes up the whole back seat, but would I lose quality?<br />Do good RCA cables really matter at all???<br />Any help would be great! Thanks!!
