ryde2idie Posted April 17, 2009 Author Report Share Posted April 17, 2009 Your box is far too small for a start... it's probably a loading issue. book says best recomendations for 750watts was like 1.5 cubic feet. Quote Quote Link to comment Share on other sites More sharing options...
banginAltima Posted April 17, 2009 Report Share Posted April 17, 2009 book says best recomendations for 750watts was like 1.5 cubic feet.

thefordmccord Posted April 17, 2009 Report Share Posted April 17, 2009 I have messed with a few trunk cars that were louder with the trunk open. It was fixed by doing a sub forward and port to the side setup.

ryde2idie Posted April 17, 2009 Author Report Share Posted April 17, 2009 Take that book and toss it.... put them in a 3 cubic foot box each. why 3 cubes? and i solved some of the problem and made it louder i stuffed fabric in all the places where the air was free flowing thru then cut a hole in the trunk floor and used a heat duct thing and made an elbo that went to the rear bumper to keep water out then installed a few layers of chicken wire. i know it sounds ghetto and "rigged" but this was the only thing i could think of to do. it has a beautiful tone to it now and its nasty loud (To Me) i believe it was a sucess and ill take some pics to show you guys. thanks for the help.

keitare Posted April 17, 2009 Report Share Posted April 17, 2009 Take that book and toss it.... put them in a 3 cubic foot box each. its a sealed box must subs sound better is small sealed boxes then large sealed boxes Quote Subs are like titties, They need to come in pairs because ones and threes are just wrong, and larger amounts will always draw a crowd, we all have our favorite sizes, but the bigger ones are more fun to watch move.

BJD3 Posted April 17, 2009 Report Share Posted April 17, 2009 its a sealed box must subs sound better is small sealed boxes then large sealed boxes But generally speaking they aren't as "efficient." I'm taking that to mean small boxes produce tighter sound, but it isn't very loud. Quote Anti Peel and Seal...lol You may be offended by the above.
