I have a Dodge Charger, running stock electrical, I have 3 OA 12s, crescendo 3kwp, PPI 900.4 on the mids and highs. Also was thinking about adding a battery. OK I was running 2 12s then I got the bright idea to add a 3rd. So now Im debating on either running them sealed or ported. My max external dimensions are 15"h x 31.5"w x 30-32"d. I would have to face subs up if I ran ported. Anyone have any input or suggestions? This is a daily driver, not chasing any numbers just want it loud and to sound good.
