Am looking at removing my under rear seat 6x9 speaker board and installing something on the parcel shelf. I recall from my college days in the early 90’s I installed a pair on the parcel shelf and they sounded super! Someone told me the boot space was like a huge air enclosure for them! Don’t know if that’s BS or not! They definitely sounded good being driven from just the head unit.
I’ve got an amp running the 6x9’s but my current Alpine HU has failed so replacing with something Bluetooth compatible but was wandering about installing speakers onto parcel shelf. I guess the tank will get in the way?
