wanting to add one to my Av so I can listen to the stereo for long periods of time with no worries of a dead battery. 


not sure what I really need/want.  Anyone have any info on this mod?  I've seen a few but bever got any details on it.

ideas?  suggestions?

:help:
 
If you mostly for daytime hours you may want to try this on the AV

looks like a great way to keep a batery charged, but I don't know how effective it would be running a 2000W stereo for hours at a time.

yeah, something like that.  I think I'll stop by tomorrow and see what they recommend.

requires more research.  are you once again waiting on me to do all of the leg  work and then you show up for the easy part?

yup.....
 
    You know at first I was going to watch this thread and see if Grn and Dune would just beat the hell out of each other over this subjeck. But on an intellectual level it's interesting to me. So I did a little pencil and paper math...

    The math to convert watts to amps is watts/volts=amps. So 2000 watts divided 12Volts=166amps. Well 2000 watts is the system performing at it's maximum. Figure you are gonna run it it half power. That's 83 amps. So I'd figure on at least an 80 amp converter to sit there and run your system. Unless you like Neil Diamond. Then go with a 20 amp system and a .45 caliber handgun. That would give you all you need >:D
    I can't remember if you have a dual battery system. However I think a dual system with power for your toys isolated to the secondary power system. Hook up the converter to charge the secondary system, and you should have no worries letting it jam all day and night
    Well that's all you're gonna get from me. If you need anything else call the Navy I hear they do wonders with small nuclear reactors.

it'll end up as a dual battery, dual alternator with all of the A/V goodies and lighting completely isolated from the stock system.

the only thing is that I don't know where I need to start.  it's probably one of those things that will be much easier if I do it all at once.
 
Hmm... Where to start...
    Step #1 It seems to me the dual alternator/dual batteries is the first step. You got to have the power before you can use it. Absolutely without question spend the extra money on the Odyssey battery for the Secondary system. It will save you heartache and misery in the future.
    Step #2. Wire in the new electrical system (Auxiliary power distribution system Wires Fuse block, pre-wire for the Converter. Try to build it as a wire harness. Maybe some of those cool stinger boxes that Dave has.
    Step #3 Install all of the goodies and wire them to the new harness.
    Step #4 Field test make sure the truck is 100% able to power everything and charge all works well. This is your opportunity to see what your actual power usage is so you can tweak your power setup and make sure you buy the right size converter.
    Step #5 install the converter. Now your toys will be able to run without the support from the truck.

    I think if you do it in those 5 phases you won't have to kill yourself by dumping all of your money at once. You pick up little time stops to check and re-check that you are ready to proceed to the next step. You can do each step over time without having to crash install anything. I am also gonna put this suggestion out there. You may want to go ahead and install E-Fans during that first phase. You are gonna lose a few horses by going with the dual alternator system the E-fans will help. Either go with a Flex-a-lite or talk to Aries. He did a setup that used an LS1 fan and plugged it into the PCM with help from HP tuners to get the truck to work in a stock E-fan setup. Though it may not work on your 2002 Avalanche. Also talk your plan through with Adam at Nations. No one knows Alternators better than that guy. He'll be at MCM next month, and he likes a cool challenge.

You better get to work on this project, or Dune will have these directions and his truck delivered to a shop and have it done before he gets back home from a business trip.

this one set a world record at NOPI ATL last year...? its either 9 or 12 alternators, 13 subs, 50+ amps and a whole lot of bracing.? When it 'only' had 36 amps and 72 batteries, it was pushing out 115,200 watts of power. (its in the 180dB club? :eek:? )

you know, 420greg has one of those...he had an audio shop install it in his passenger side tool box. ... I don't remember what size it is, but, I'll bet he talked about it somewhere over at TOOS

thx.  I saw the thread he started.  It really doesn't go into much detail.  Just basicly says he installed one and this is the specs.  Since I eventually want to add a complete 2nd charging/storage system, I want to do a lot of research to be sure I get it right.
