bassrace Posted November 1, 2011 Report Posted November 1, 2011 Do you have alot of bracing? Or double baffle? B/c I get your right around 6.9 cuft net before port displacement. 2 6" aeros is too little of port area 3 4" is even less... You could go 1 10" ...? But it would be fairly long...or 5 or 6, 4" aeros... Let me know what suites you and I can give you some lengths. 145.9@40hz 145.3@34hz big 3 X2 group 34 Deka Group 31 All 0/1 awg jl meta wire Alpine CDA 7894 Orion HCCA D5000 2 AQ HDC312's Crunch gpv1100.2 (for 6.5"s only) AQ pro audio 6.5" - 3 sets AQ supertweeters - 2 sets 2000 Slamry
412 CVX Posted November 1, 2011 Report Posted November 1, 2011 this is getting really complicated and messy and overall there's not nearly enough information to give you an accurate answer. i really think we need to start from scratch here. 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.
