Hey guys, first post! I have a question about the current setup I'm getting ready to install:

So far I have:

-(2) 12" MTX Terminators in a closed box, 400 watts RMS each

-(1) MTX Terminator TNA251 amp at 250 Watts RMS

-(2) 6.5" 3-way Kenwood KFC-1664S at 35 Watts RMS

-(2) 6" x 9" 4-way Kenwood KFC-6984PS at 110 Watts RMS

-(1) Kenwood KDC-248U Head Unit

I'm going to use the amp to power the subwoofers, but it looks like the amp's a bit underpowered. I only question if the head unit can provide enough power to the door speakers...do I need to buy another amp for the four interior speakers? Should I buy an entirely different amp? Thanks for your help!
