What size is the alt on the 05 TL? Does anyone know the amperage it puts out at idle and at higher RPM? Reason I'm asking is that I am putting in a system, running 2 eD NINe.1 amps, and 2 eD NINe.2 amps running 2 sets of eD 6500's and 2 Diamond Audio D9 subs. Plan on putting a Red Top under hood, and 2 Yellow tops in the back, and was wondering about upgrading the alt, if it is needed later. Will be dual runs of 1/0 ga throughout the electrical system providing a nice smooth trip for the voltage throughout the system.

 

There is my ghetto-quick install plan. Expect a better one as the build gets closer.
