upgrade an alt for 1k watts? not sure i agree with that

If money is not an issue (and you can afford / series amps and w7 it probably isn't) it saves a good bit of space over an extra battery.

ok been doing alot of reading and fallowed all the instructions on jls website. think i got it right. the gain is now at a little less than half. but it is still draining all the power in my truck.

1000 watts should not drain your batt that bad, specially you have an SUV which usually have a bigger battery

Those amp are around 50% eff, they will kill stock electrical. Thats the sacrifies for doing what they do. The gain being way to high was a very bad thing but you are going to need some electrical support for it.

the gain has been properly adjusted now. still having the same problem. im going to look into how to do the big 3 upgrade then go from there. if that dont cure the prob then ill upgrade my battery up front. if i still have a problem then ill prob go with a kinetik batt in the rear. the last thing i really want to do right now is dish out 500 bucks for a ho alternator. but as others have said i dont think that a 1000 watt amp would need all of that. im not sure how old the batt is in the truck. i just inherited the truck from my dad. so for starters im going to autozone to get the battery and alt tested.

thinking i need to do the big 3. my battery and alt tested 100%. does anybody know where i can get the stuff to do it. and also a write up on how to do it. i have heard of people messing up these trailblazers trying to do the big 3 so im kind of nervous. had a couple places try to charge me 100 bucks to do it.

is that 100bucks with their materials? whenever you add the wires jsut leave the stock ones in place
