Andrew Storlie Posted April 30, 2015 Report Share Posted April 30, 2015 im currently working on planning/building a system for SQL in my jeep. nothing crazy, only about 1000rms at full power. the amp im going to be using is fused at 80 amps i have a few led light bars that draw about 60amps when they are all on, which isnt often. some other custom lights and stuff, and of course the power the jeep takes to run... i plan to have a SINGLE d4800 xs power batt under the hood which should be plenty to power everything with out voltage drop. but i do play music while parked and just sitting around. will running a very high output alt 360amp and 180a at idle (as im told by stinger) damage the battery if im not drawing that much power all the time???? I want to have as little voltage drop as possible, if any. if i can keep my jeep at 14 volts minimum i would be very happy, that includes running led bars and full blast music.

Miguels Posted April 30, 2015 Report Share Posted April 30, 2015 Your alt will supply the amperage needed to maintain voltage. If you have 360a alt and you only need 150a to maintain 14.4v then thats all you will get from it.. One thing though.. If you're planning on playing stopped with car off you will damage both battery and alternator. A.dead battery will over work the alternator. The other thing is once the battery is dead dead the alt will be at max dumping 350a amps max 180a at idle making the battery overheat and swell my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
SPL.Pantie.Soak Posted April 30, 2015 Report Share Posted April 30, 2015 Boy oh boy thats a big alternator for your application, but no it will not damage your battery or car in any way, it supplies what is needed.

Miguels Posted April 30, 2015 Report Share Posted April 30, 2015 I would opt for a 250a hairpin. You don't need 350a and the 250a will be a better option for idle. I doubt you get 180a at idle with a conventional alternator no matter the company you get. I have had both mechman and singer conventional alternators and both sacked at idle at 650 engine rpm. Went with hairpin and they love low rpm my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

Hairpin a brand? And i wont be running the lights and system and lights with the jeep off, ill be running them while the jeep is idling. Which is why im looking for idle amps over peak amps output Link to comment Share on other sites More sharing options...

My small 270 HP will smash your 370 at idle....... my 370 hp does over 200 at idle.... around 700 rev the 270 turns on at like 400.... its a tank...
