im not trying to run a constant 2000 watts into these subs tho.. dont want them gettin killed in a year. i play my music loud i couldnt go with a ph 2500 and get a 1250 rms into each one? turn up the power and get a little bit more? have you seen what those subs do to a car? whole door will be flexing and doin the wave.. not trying to power those things all the ways like that
and i have a extra marina battery
the 2500 would only throw 625 rms to each one at best. this is going to cause voice coil overheating most likely since its enough power to get it hot but not enough power to keep the subwoofer moving enough to cool it.
rms rating is there so you can get an idea of normal operating power which is crucial to it working properly.
batteries are back up power and won't help anything other than cost you money. you need to upgrade your alternator(unless you have a 200amp or higher alternator already) and do a big 3 upgrade in zero gauge wiring.
