For simplicity sake and cost savings I recommend a single amplifier. You dont need a 5 channel amp. A 4 channel properly configured will be adequate. Also Class - D amps are more efficent and will be easier on your electrical system. Most people dont realize that a car audio amp will quickly destroy your battery and alternator if its drawing more current then it can support.

I would not exceed 600 watts rms total in this car without changing your battery or you will be replacing it in a year or less.
