Subwoofers in a cruiser mopar

Have done it on many cars. Really depends on what you want it to look like in the end. You can do a generic enclosure and use MDF board if you are good with wood. With wood you could get into many angles depending on how you want the box mounted, how big it needs to be or if part of the box is going to be down in the quarter panel. Or, you could do all fiberglass. Or a mix of the two. To get the best sound you just need to make sure the enclosure is the right size and you have the right power for the subwoofer. It is best not to have a perfectly square/rectangular enclosure anyway. I was happy with the way they all turned out just while testing them. They were not all my cars but never had any complaints.
