I'm currently running two alpine amps... a MRP-F450 for my highs and a MRD-M605 for my 12" Type R, only problem is I want more bass. In my closet I have another MRD-M605 and 12" Type R. I've been going back in forth about installing them or selling the two amps and getting one 1000w at 1ohm amp (not sure which one). The only reason I would sell is because I really don't wanna run a 3 amp setup in my car off the stock alt and a yellow top. Am I wrong by thinking these two amps will pull more from my car the one big amp??? Any insight would be appreciated....
