alpinef150 Posted March 30, 2013 Author Report Posted March 30, 2013 Kranny. Yes it does. I used that exact diagram.
Guest Posted March 30, 2013 Report Posted March 30, 2013 how did you tune the gains on the amplifier?
Jessica Posted March 30, 2013 Report Posted March 30, 2013 Well, i would do like kranny said, double check wiring. Compare the terminals on both subs too, It does happen sometimes that a "+" and "-" get miss labeled. Also, we are still waiting on pics.

alpinef150 Posted March 30, 2013 Author Report Posted March 30, 2013 im not sure what the gains are set at exactly, I played with them so much yesterday to try and fix the issue. and right now it is only single layered but will be adding another layer of 3/4 mdf along with 1x1 bracing and possibly glassing the inside as well. I just cant picture a little flex and a few small leaks making it sound this bad
Jessica Posted March 30, 2013 Report Posted March 30, 2013 Well, i had 2 12's in a box on like 300, single layer and it was a sealed enclosure. The baffle and rear board flex was bad enough it sounded like crap crap crap.Put a brace in the center, and bam, i had decent bass. You are throwing a lot more power, and a hell of a lot more cone area and motor force. I can't imagine a box that big, single layered with no bracing would not flex like crazy. If you did indeed build to those specs, you should be ok, but you really need to brace that thing up. Of course i am only guessing because of course i am not there seeing what is exactly going on. Like kranny and others have said, wiring, leaks, port placement, box placement, gains, crossover settings or a million other things could be wrong too. Wow, i tend to ramble.

alpinef150 Posted March 30, 2013 Author Report Posted March 30, 2013 here are pics of the box as it sits now. its a little lopsided because I still have to notch out a tunnel to fit the wheel well. please excuse the disorganization. its all just for testing at the moment.
alpinef150 Posted March 30, 2013 Author Report Posted March 30, 2013 Oops the third pic is upside down.
john253a Posted March 30, 2013 Report Posted March 30, 2013 try a lower tuned port do the max length before it need to bend, and see if that helps you might be unloading
alpinef150 Posted March 30, 2013 Author Report Posted March 30, 2013 Ok since it is 17.5 wide would I need to stay that far away from the back wall?
alpinef150 Posted March 31, 2013 Author Report Posted March 31, 2013 Well added some bracing and it did the trick. Still not slamming yet but definitely sounds much better. Thanks for the advice everyone.
