how about running a seperate battery in the trunk..yellow top...running a system off this instead of putting it under the hood and running everything off it whats the consecquences..the battery wont charge unless its wired to the altenator wont it? if i use a seperate battery for the system then i wouldnt have to replace the alternator..what should i do and what happens when i do any of these..
Yes you have to connect it to the electrical system/alternator, lol. If you use an isolator, you can run the audio system off a separate battery than the other accessories.
And an extra battery does not replace the need for an HO alternator, and will not do one bit of good if the alternator is not good enough.
