DStortz Posted May 23, 2011 Report Share Posted May 23, 2011 Hey everyone, Well all of my equipment has been ordered and the fiberglass tonneau cover should be here in about 2 weeks. I am doing a blow through in a 1978 chevy full size pick up. I have no idea on how to do the box for this cause I have never done a blow through and the people that are going to be helping me have never made anything this big before. I basically have the whole bed of the truck to work with minus 2 feet for the amp and battery rack. So I am hoping that I can get some design ideas from someone here that has made bigger builds like this. Here are the measurements that I am looking at. 5 1/2' long, 50" wide, and 22" in height. There will be 8 JL Audio 15W0 subs (please don't bash). Each sub requires 2.75 Cubes. I would like to tune it to about 35hz. I thank you in advance for any advice and help. Once the cover gets here and building starts I will be taking tons of pictures and start a build log on here.

DStortz Posted June 9, 2011 Author Report Share Posted June 9, 2011 http://i1214.photobucket.com/albums/cc490/dstortz/bOX.jpg Here is a box design that I found, that I think we will be using for this build. There will be more of a V shape to it.
