bassrace Posted November 23, 2011 Report Share Posted November 23, 2011 (edited) Not enough port area. Shoot for 12-16 sq in of port per cu ft.

Quiet Posted November 23, 2011 Report Share Posted November 23, 2011 How many SA8s? Your top plate doesn't have enough space for 2 8 inch subs. Needs to be atleast 18-20 inches wide if you're talking about 2 subs. Quote 2007 Pacifica Rebuild. Less quiet. Still not loud. Link to comment Share on other sites More sharing options...

Are those your max dimensions Quote 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 Link to comment Share on other sites More sharing options...
bassrace Posted November 23, 2011 Report Share Posted November 23, 2011 (edited) Are those your max dimensions for both subs or is it for one.(regarding your last post) I'm not particulary fimiliar with those subs but I would think you might want to tune a little higher also, maybe someone with a little more knowledge with these will chime in.
