Alright so I have 2 JBL MRX 518s subs and a crown xti 4002 powering them. They are both 4 ohms and peak at 2000 watts. So I want to put more power through them considering the xti only puts out 1200 a channel at 4 ohms. I was thinking of getting 2 crown xls 2000 drivecores and bridging them to each sub. Would this be a bad idea and if it is what other amps would you recommend. Any answers would help, thanks guys.
