This will be my first attempt at a decent install. Comments and suggestions welcomed.
I had a couple of systems when I was 18, I'm 29 now. But nothing decent or installed worth a crap. After lots of reading and research I decided to try and put something decent in my daily driver. After hours and days of reading Sundown Audio seemed to come up the most. So I did a little research and decided to go with them. This build was ment to be a budget build with a $750 cap. Its closer to $1200 now but in the scheme of things I'm still considering it a budget build. I'm going to include prices in case anybody is interested in the break down of the parts list.

Hope to have everything installe by this weekend. I'm still waiting on the amp and speaker wire to arrive. But whille I had some free time today I went ahead and fabricated my Big Three upgrade and installed it. I currently have a JL Audio 500/1 Mono block in the truck fed to a JL 12W7 in their H.O. box. I tested the voltage at the amp before and after. Before it had 14.5 volts at the amp and the lowest I could get it to drop was around 12.1-12.2. After I did the Big Three upgrade I again measured the voltage at the amp and it was up to 14.75. The highest I seen was 14.77 quite a few times but it stays at 14.5v for the most part. Lowest I could get the voltage to drop using the exact same procedure as before was 13.2. This was after 30-50 seconds of a 40hz sine wave.
Cut to length with ring terminals crimped and heat shrink.
