I am looking for advice on the best, most efficient subwoofer enclosure design for my 2003 Cadillac Deville. I want to install either 3 or 4 12" subs, sealed enclosure, but its been 10+ years since i have been involved in car audio. I know that the knowledge base and available designs have increased quite a bit since i was involved in things...
can anyone offer suggestions or installation pictures?
thanks in advanced
