so im a musician who needs to use his boot and fill it a lot, but i'd like a nice sub in the boot and amp, is it possible to make a unit which contains the amp and sub and fits on the wheel arch of one side of the boot that i can take in and out easily this way when its in it doesnt take up to much room and can come out easily!!!, i have a mk3 driver any ideas or suggestions would be great, also sizes etc, im approaching this with a completly open mind.
