I just bought a single 12" S12L7 Kicker Sub with a KX600.1 kicker amp. I am going to built a custom box and also have a nitrous bottle in the trunk.. I need ideas figuring out the best way to mount the sub and amp, move the nitrous bottle, and save as much space as possible. I want to build a vented box, and I can provide any specs if need be on the sub. Pictures or ideas are WELCOME! PLEASE HELP!
