Just bought a 2000 watt hifonics, never had an amp that big b4 so I dont know if the 1 run of 1/0 power wire is good enough. Also I can't afford a high output alt rught now, will I be ok stock, with a optima red up front? Also does big 3 gotta be 1/0/ I did 4 awg. Help me out guys!

My first Optima went bad, it would only charge to 12.1. I had a Duralast in the trunk too though. Don't know if that is what killed it. actually both batteries died. Warranty on the red top got me a new one free. How do I test voltage drop.

IF you run 1/0 to the amp, I would run 1/0 everywhere else too.. u gota look at it as a series circuit. Electrons flow NEG to POS in a techs world, but Pos to Neg in an engineers world... either way, they gota flow from the ALT to the Batt, from the Batt to the amp, from the amp back to the frame, from the frame back to the engine and alt.... so that would be like running 1/0 power to ur amp, and 4 guage as a ground.. what would be the point in that? I would upgrade ur alt soon. run the formula on High Output alternator.com website, go to Ricks Technical info.. hes got good formulas i think. figure up ur amperage draw, then go from there on upgrades for alts and batts.

you cant? why not? I heard that if the batteries have the same internal resistance, that you can run more than 1. Just run them in parallel. I ran 3 stinger SP1000 batts for a long time just fine

I agree, I have done and also seen this done several times by myself and several other professionals. A lot of installs feature a battery in the engine bay and another dedicated to the stereo system in the the trunk that is a different brand than the one up front. Running them in parallel has never caused a problem for me or any of other installs that I've seen.

No 2 batteries are the same, even if they come from the same company. one will always be stronger then the other. Remember, the second battery is to power your system longer when your car is off! if you don't hook up an isolator to separate your batts, when the engine is off, your system will be pulling from both batts, and if you do it long enough, when its time to start your car.. your gonna be ass out! with the isolator, you can drain your system batts but still have enough juice in your other battery to start your car and go home!
For example,I have the same amp pushing my L7's and another one for my mids and Highs... all powered via a Kinetik 2400. while my OEM bat takes care of the rest of the car!. Trust me, ya don't want to get caught out there with a dead batt!

An isolater allows both batteries to be in parrellel when the ignition is on, so unless you have an alternator that is big enough to handle all current, then you are back to the same spot.
I wouldn't use an isolater. It has diodes in it that rob you of voltage.
Get two identical batteries (as close as you can) and wire them in parrellel. Mount them securely, make sure they are vented properly, and be done with it.

some do and some have a switch. when one battery is fully charged, it will switch back to the other battery. less strain on the alt trying to charge both at the same time.
robert, Some people use them....some don't. here is some info for ya to check and make your own choice.
