Installed facing down into the spare tire well of a 94 civic.Powered by a 500/1. I have had the 13w7 12w6v2's etc. and love them. I purchase this in hopes of retaining my trunk space by using nothing more then my spare tire well. and if it wasn't loud enough i would just put it under the seat of my truck and use the one of the other jl models in the civic. Thats not going to happen though. This thing not only sounds good. it is powerful.... Looks like i will be selling my other models for these. Only drawback is the mounting flange is rather small between the tabs. Will need to get the mounting hole just right.
