Joe X Posted March 9, 2012 Report Share Posted March 9, 2012 1200W is very little power for those subs, you should set 1.6 cubic feet per sub that pioneer recommends which will increase efficiency and output, I imagine that you have the space in a tahoe.

412 CVX Posted March 9, 2012 Report Share Posted March 9, 2012 The design i gave him gives each woofer 1.4 cubes. that's plenty. Quote Just say no to Ground Pounder Customs.

Joe X Posted March 9, 2012 Report Share Posted March 9, 2012 joex what do u think Big vehicle lower tuning probably will not get that loud if loud is what you care for. Pionner recommends up to 1.6 cubic feet per sub, it will be safe for the subs up to rated power for sure, a small gain for a bigger box if that makes sense to you. It's more like you will benefit from sourcing more power. Quote Link to comment Share on other sites More sharing options...
