ok so i have recently decided to upgrade the sound system in my jeep i have 2 subs one 800w pioneer 12" and one 1400w xplod 12". and i was wondering if it will make a difference to run both of them in the same car from one 1400w xplod amp. the guy at the store said it would be ok but he didnt know they were different brands. my question is does it matter that the two subs are different or should they be the same. also if i decide to get another 1400w xplod rather then the 800w would the 1400w xplod amp be enough.
