I was pretty close to buying a Red Top formyself on eBay for about $130 shipped...
Went to Discount Auto to buy some brake cleaner, and saw the Red Top there for only $109... so I took it!
I bought some terminals and this special "thing" (don't remmeber what it's called) to connect an additional terminal on the side for all my aux equipment (amp, inside/outside neons, 3 TV's, etc.).
It's pretty nice, and I can tell my car starts a bit faster, not that there was a problem before, but it's much better now. I plan on getting a cap for my subs in the trunk too. I'll take and post pics soon!
