I thought I needed an hour more work today but it ended up taking like three. I was experiencing some vibration sounds yesterday so today I removed the 4 speakers and stuff the area behind them with a lot more pollyfill (pillow stuffing). This ended up improving the sound quality and killing any vibrations I was hearing. I also cleaned up the wires in the rear, and fastened my amp and subwoofer into the trunk.
Even though I have the amp and sub installed in the trunk, when the rear seat is folded up there is still a lot of room for Geo to get in, sit and walk around. When the rear seat is down the amp is hidden and there is still some room next to the sub for some grocery bags.
I tuned the sound system a bit but will wait two more weeks for all the speakers to break in before I spend more time tuning things. Although it was really exhausting work it was a good learning experience. Next project I am probably going to try is to install is a suspension lift by myself. I already have the step by step instructions just need to get the right tools.
