the battery is inthe trunk?? that is something i did not know but dude make sure when installing the amp the ground wire from the amp to a ground cannot be more then 6-8 inchs or the amp will not be able to ground properly and heat up. also for your power and ground make sure you use some fat wire at least 8 guage.this depends on how much power you are using if its more then 300 watts you want at least 12 gauge wire anything less will be a fire hazard.
