I have relocated my battery from the trunk to under the hood (yes trunk -> hood)
beacause my car was hard too start, starter was spinning too slow and too hard with extended wires.

you could always get a tiny ass Motorcylce battery or that battery Mad Machine bought. And place it where most people mount there MSD units.
That'd open up your battery tray space. BUT, you'd be giving up thumping bass and cold starts are a b****. plus if you ever leave your lights on your are Fuuqhed.

Honestly, if done right a battery in the trunk will not hurt your cold starts that badly. My fiat has the battery in the trunk STOCK.. as do a lot of italian cars.. They just run a 2 guage wire from the positive to the starter. The negative grounds right to the body next to it in the trunk. It would have to be VERY cold (below zero) for the car not to start.
I know it is dirty and full of junk...

After a few feet of wire you start to run into resistance problems. There are electrical safety standards.
http://www.powerstream.com/Wire_Size.htm
basically, the less wire you have in between your battery and starter, the easier it will be for your starter to start. you will never be able to get the full 700 cold cranking amps out of your battery ever, but it may drop to 500-600 if you relocate it to your trunk, even with O or OO gauge wire. Don't go cheap on wire, it's worth spending the extra to get sterio quality wire and terminals and do it right. Once you get past the 700 circular mils per amp rule, you start encountering alot of resistance.
EXAMPLE:
900 watt sterio amplifier- wire pushing 60 amps at 12V
4FT of 4 AWG wire = 11.8V at end
4FT of OO AWG wire = 11.9V at end
12FT of 4 AWG wire = 11.4V at end
12FT of OO AWG wire = 11.8V at end
Keep this in mind... you might want to use OO gauge
