I am just adding a little thump in the trunk and need some last second help. I just found a box and threw a 12" sony speaker and amp onto it. I wired the relay in and hooked up the ground and power as well. I want to tap into the rear speakers to get a signal for the amp but there is a ton of wire and rather than taking a while to sort it out, wondered if anyone here knows off hand what to look for. do the bottoms of the speakers just unscrew out to reveal the two wire leads on the speaker? I know the gear is nothing special, and proly sucks compared to everyone elses here, but I wanted something to add a little extra kick in the rear that I could take out easily for when i need. Just a box for a 12' speaker with the amp attached to the back of it, i affectionately call it a "bump back"
