I have a 2008 350z base that I installed the following into,

- Optima Yellow Top Batteries
*1 under the hood
*1 in the stock subwoofer cubby
- Rockford Fosgate stereo system
*Doors - T165-S 6.5" Power Series Component w/ crossovers and tweeters
*Stock Rear location - T165 6.5" 2-Way Full-Range Speaker
*Subs - 2x T1D210 10" Power T1 2-Ohm DVC Subwoofer in zEnclosures box
* T1500-1bdCP 1500 Watt Class-bd Constant Power Amplifier pushing the subs
* T800-4ad 800 Watt Class-AD Full-Range 4-Channel Amplifier running everything else
*3 farad cap

My thought is I need to upgrade my alternator to something that has a higher output. I am having a hard time finding one specific to the HR motor. Does anyone out there have any experience with using a HO alternator on a HR motor? Any Thoughts on other things I might need to make my stereo system more complete? Any help resourcing a HO alternator would be much appreciated. Thanks Guys!

 

i have the same year make and model as you do and this guy here www.excessiveamperage.com. he can build you a 200 amp alternator for little around $400 i had him make me one for my 01 kia sportage and i had it for over 4 years now pushing 2000 watts and no problems.

 

Who recommended you to get a higher output alternator????? Based on your build all you need to run is just 2 amps and HU. Stock alternator and 1 optima yellow top will do this work just fine! I have ARC SE4200 and SE2300, HU, separate bluetooth, Garmin GVN53, Mosconi sound processing, DVD changer, HDMI to composite converter (using separate power), HDMI adapter for my phone (also separate power), phone docking station, V1 radar detector, LED's in the trunk - and even to power up all of those stock alternator (110A) works just fine! A lot of cars running 80A (like civics etc) - those you need to replace to have a decent sound system but for our cars unless you loaded with amps, you will be just fine.

 

The thought of a high output alternator was the total wattage of my system on paper is a little over 2700 watts. and I also have a second battery that's ultimately another load on the stock alternator on my HR motor which is a 150a alternator. I understand that I would not reach this peak wattage while playing just music but I do estimate a realistic stereo draw of roughly 145a so I would be exceeding the stock alternators output which would ultimately lead to failure.
