Thinking of getting rid of my three AQ 1200D's and strapping two of these RF's together. I never hooked up two amps to three subs though so not sure how I go about doing that. The BL's are dual 2 so I'd be running all three to a 3ohm load and the the RF's will be at like 4000 at 2 ohm correct? So I'd see a little less than that at 3ohm. To strap these do I just need the the bd strap cable from rockford, or do I gotta go about and connecting wires and make one of the amps for the positive of the sub and the other for the negative or whatever that combination is.
