What kind of amp do I need to power infinity kappa 62.7i's? # 2-way car speakers for 6-1/2" and 6-3/4" locations (pair) # 2-ohm impedance for extra power (compatible with all factory or aftermarket car stereos) # rotating UniPivot M.M.D. dome tweeter # computer-optimized outboard crossover with tweeter level control # power range: 2-75 watts RMS (225 watts peak power) # frequency response: 45-25,000 Hz They are only my rear speakers. Also I have a dual subwoofer with a kenwood amp already and I was wondering if I would need to do anything special to power two amps.. Is it possible to have another battery to just power the speakers?
you infinity speakers are 75watts at 2ohms i think. what do you have for front speakers? If you really want to be anal about it then you can just get another kenwood amp that would put out 75watts per channel at 2ohms. The Kenwood KAC-6202 which puts out 100watts per channel at 2ohms fits the ticket. do you want to use a 2 channel amp or 4 channel amp? in order to power two amps all you'll have to do is buy is distribution block. Instead of running your main power line from the battery to the one amp that you have all you have to do is run that line to the distribution block and run two power lines out of the block. For the grounds, just have a common grounding point. For the remote wire just connect the remote to one amp and have another wire going from the amp remote to the other amps remote wire. you should be in good shape then. You don't need another battery for powering your system unless you are pushing some serious wattage. I'm well over 1000watts RMS and i'm just using the stock battery and alternator....
