Well right now I have the Cadence ZRS-10 2500 watts rms, so roughly ill be pushing 1250 watts per sub, and with the gains set correctly I think I should be fine.IMO you dont need 1500 on each TC2K unless you wanna fry em. I had a TC3K an 1500 pushed that pretty good. 2 15s on 2000 will be PLENTY in that car.
