Hi guys, I just want to try something out: Auto is a Corolla E11 Compact Subwoofer: Audio System R15FA Power Amp is also there with enough power and the car actually has a system, but serves so little to try out. I want to install the subwoofer that is currently just lying around in the trunk as Free Air. Luggage compartment has almost 300l volume. Now the consideration, how do I build it the best? Does this work in principle when I build it as Downfire, so put out an MDF base plate with cut-out for the sub and its membrane pointing down towards the spare wheel? After that optimize the trunk from the inside as well as possible. I’m open to all suggestions, as I said, is rather an experiment, what actually goes there.
