What upgrades have you done to your electrical system ?

150+ ampere alternator I hope ...

nope don't have 650 bucks for the upgrade.

With a larger draw system, it is very important you upgrade the factory wiring and electrical system. It is not important for you to have a larger alternater, as the factory one should be adaquate in most cases.

1/0 ga upgrade
Solid new large battery
Electrical system upgrade(factory grounds ect...)

See how that does before spending any serious money. [img]smile.gif[/img]
