So I recently purchased a 1000W amp. I started thinking on what I need to do and quickly realised that the factory 2.6L alternator may not be enough power. How big of an alternator is factory and what do I need to power the bluetooth radio and 1000W amp I have thrown into the mix? I read that factory is 45 and the upgrade is 75 and that's nothing to what I need. Please help, thanks!
