eric you said that the Diamond Audio CM3 15 was a good sub (which is looks to be) and also said to get the JBL BP600.1 amp. Now i need to know wether to get the CM315D4 OR CM315D2 (Dual 4 ohms or Dual 2 ohms) this is the last thing i need to know. Thanks a million eric.
you will choose d4 or d2 based upon the amp you get so dont order the sub until you get an amp. BTW, I think the jbl is 1 ohm stable so you would get dual two ohm for that.
