So I have a 2000 monte Carlo and I want to upgrade the audio system main point this is what I need help with, I want too put two yellow optima and 2 2000 watt amplifier (bxi2008d) would like help with the wiring, what I have currently is one optima and one amp, 2 9in headrest and 25in flip down, some specifics with the wiring would help especially wiring the two optimas together

 

Run a main 0 gauge power wire from either your front battery or to your alternator (and a ground if want) to where your 2 optimas are and then then just hook it to the power post on one of them.. Then make a little jumper to from the power post on the first optima to the second one.. And do the samething with the ground.. Use all 0 gauge of course... Its called running them in parallel.. Theres a few very talented audio guys on here..'good luck man!

 

Don't forget to upgrade alternator or add 2nd if you haven't already bro. Best of luck
