I am looking to build a slotted box for 2 alpine SWS-10d4 and I had a couple of questions.
First, I was thinking about using the Massive D2400 to move those, I have the D3600 pounding 2 JL 12W3 and it pounds, and the price is good for the amp. Any suggestions for a better amp for the same price?
Second, about positioning the sub box, was thinking of facing the speakers to the rear and the ports into the car. How would this affect the sound? Or do should I face them both to the rear?
Third, I am using the RE Box calculator, if I tune the box to 35hz would that be for any speaker I put in it? 10 or 12? I would think that frequency would change depending on what size speaker I use?
