I have a Pioneer amplified sub tube in my Delorean. It is placed in the parcel self area and a nylon strap secures it to the rear firewall. The nylon strap is secured to the firewall with two screws. The strap wraps around the tube and tightens like a belt securing same. The tube sounds great and with the amp that powers it being built in it does not take up a lot of room. Plus it only takes about five minutes to remove it and again you have the pure stock look.
