6x9 Sound Ordnance Bass Bunker boxes
Crutchfield Customer Review (What's this?)
The boxes are solidly built, covered well and should last the life of my vehicle. The only problem I encountered is the 6x9 speaker opening is rather large for the Pioneer speakers I mounted in them. You have to be careful to center them, if you don't you may not have a board under the mounting hole in the speaker. Another brand of speaker may fit better and solve this problem. Just something to be mindful of. Also the larger 6x9 box is rather tight behind my truck seat, but that is my choice for getting more cu. ft.
Pros: Built solid, easy install, fair price.
Cons: Rather large 6x9 opening, spring loaded connectors could be a little stronger.
