I have a set of MMC690 in my 1996 Honda Civic. It sits in the stock location but this doesnt give a good sound. The guy at my local shop told me i should build a box around, and he let me listen to the setup he had in the shop. e had the mmc690 build in a box and ran it straight from the headunit. This sounded way better then the setup in my car wich is similar but without the box.
Did anyone build a box around some 6x9 if so, how big should this box be? If anyone could help me with this i could start building one soon.
