last week i hooked up (4) kicker cvr 12's to a jbl bp1200.1 amp. They are running a 2 ohm load. The thing is, the bass just does not sound as deep as it did when i first go them. also it sounds like there is more distortion. any ideas? aslo could it be because of the area they are in. they are in a 4 door blazer. will dynamat help with the sound?
Are you sure you didn't blow one of them. Check them out individually and see what happens. good luck. Also on that amp i think it has 4 rca inputs. It makes a big difference if you have all 4 connected.
