Hi, Just bought a mk3 golf cab. I have a 5 channel DLS RA50 and Focal 3 way components. I have put the components in the front. The amp is on the back of the back seats but I'm just wondering if a sub will work in the boot. Will I need to drill any holes or anything to hear it? I was planning on buying a diamond 12" but will wait to see what people think. Any help or suggestions will be greatly appreciated. Thanks, James
