would this work? im planning on putting seleniums in each door a 6 and an 8. i planned on running them all off a kicker 850.4 for now until i can get the sundown amp i want. what my plan is... active crossover from clif designs followed by the amp. running amp 1 for the 8in and amp 2 for the 6in. i would be wiring the 8's and 6's down to 4 ohms. i know if would be underpowering the 8in speakers but for now not bad? right?
