Alright well my cheap 280 watt amp isnt great at pushing 4 twelves well, and i dont have any money to spend atm so i have a few questions. My subs are wired parallel so i was wondering if i could power 2 of the subs with one 250 watt sony xplod amp, and the other two with my 280 watt amp. Im pretty sure there would be some sort of phasing issue do the different wattage, but this is why im asking. The RCAs are also different sizes.
