412 CVX Posted March 5, 2012 Report Share Posted March 5, 2012 nah, 3.5 x 13.5 is plenty big for a pair of 12's. as long as you keep a 1:6 ratio and have 14-16 per cube, you shouldn't have problem. i usually draw my line at 1.5 inches. anything smaller than that i go with an aero port Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

Could you maybe do a wall design for me how you feel would be best with the room i have? I would like the tuning to be at 32htz 2 DC AUDIO Level 5 18s Carbon Fiber Dust Caps, Direct Leads, Stiffened Spiders Stinger SPV69, SPV70's (2) Stetsom 7KD Excelene 50+ feet 0g Welding Cable Soundstream 4.500 + JBL 1000.4 Cadence Mids + Earthquake Highs Clarion 507 BT + EQ All Stinger Parts/Adapters/ETC.
