Big 3 Upgrade

[Mcopco]

I'm installing a sound system in my hybrid and am planning on doing the big 3 upgrade. I'm wondering how all this will work with the hybrid battery. How does the hybrid battery charge ? I don't want to damage the hybrid system and am having a hard time finding much information on how it all works. Anyone done the big 3? Any help or direction on where to find writing diagrams would be appreciated.

Thanks

yes basically yer just replacing yer main charging system wires with zero guage wiring
im unfamiliar with a hybrid
but on a gas tahoe yer basically replacing all the grounds with heavvier wiring theres like 3 and i positive lead off yer alternator with heavier wire its a pretty simple upgrade but with a hybrid
from the pictures ive been looken up i dont even see an alternator

Yeah I discovered no alternator. I'm thinking I could get a stock alternator and second battery and those systems could be totally separate. But that's for the future.

 

[ccapehartusarmyINF.(ret)]

yeah that would be ideal but is it possible to mount an alternator because youd need to change belts and find a place to mount yer car batter from the pics ive seen under the hoods of those highbreads thats mite be tricky

 

[ccapehartusarmyINF.(ret)]

when you get a chance you shold post a pic of yer engine bay

Oops doubled the one but that's how it looks. I gotta assume that I could get a alternator for a 6L tahoe and get the bracket and belts. Plenty of room for sure. I'm definately not tackling that project until spring though. No garage here.

youd probably have to take that pully off and get the mounting bracket off a gas tahoe and install it in the same place and install the alternator on the bracket then hopefully the serpentine belt from a gas tahoe would work then and then if you cant figure out how to mount a car battery under the hood you can prolly install in the cab somewheres
yeah itd definatly be a chore but hey the upside is you wouldnt need to spend alotta money on a high current alternator you could just go with the stock 140 amp cuz itd just be running yer system or what ever you planned on running

I'm just hoping the current electrical can handle my 900/5 amp. Until I can figure out the rest. I've asked in the hybrid section but no responses yet. I'm thinking I should be okay. Only concern is damaging the hybrid system. If I kill the battery I'll live and learn for the cost of the battery of I break the hybrid system I'll cry. And the wife will be none to pleased.

just outta curiousity what made you decide to buy one of these hybrids i heard there pretty spendy compared to its all gas counterpart and the MPG isnt that much better

 

[ccapehartusarmyINF.(ret)]

so yer amp is 900 watts x 5 channels
at 14 volts that would only draw 65 amps and if that 900 is the peak wattage rating then itd only draw that much current if you had the stereo full blast

 

[ccapehartusarmyINF.(ret)]

whats the RMS wattage

 

[Mcopco]

Dealership had two tahoe within 2k miles of each other very similar options. Hybrid had navigation back up cam noon hybrid did not and they were the same price so figured I'd save some on gas. And honestly I get about 22mpg. Higher of in in city lower on Highway. I can get to work which is very close almost exclusively on electric because speed limits are 30. I actually have to go just under the limit to stay in full electric but.... Anyway that's basically it. I've always been a tahoe suburban guy so didn't really care about hybrid but for the same price why not. If I had known what I know now I probably would have stayed with non may because of audio. If I have to add alternator and all that jazz then I'm out a ton of money and the gas savings probably doesn't matter.

 

[Mcopco]

It's 900 rms. The jl hd900/5.

I need to figure out how to fix the gap between climate control and dash kit. Don't think I can. There is a lip on the climate control that fit over factory I could probably grind out the groove on dash kit. But I really like this HU.

 

[ccapehartusarmyINF.(ret)]

so yeah itll draw 60 70 amps

I definately don't know how to use this forum on mobile but any idea if this will be fine seems fine possibly more engine time but that's no biggie didn't get a tahoe to hyper mile

Definitely be fine. This is my old setup in a hybrid

honestly id probably talk to a more hybrid saavy person im a little outta my depth when it comes to hybrids the charging system from what i can tell is a bit different

hey hey there yah go
