i just purchased a kinetik hc1800 last night. i was going to get the 2400 but i wanted it to fit under the hood. My question was is the 1800 going to be sufficient enough for my sundown 1500d @ .5. I have 2 runs of 1/0 going to the back. stock 85 amp alt. should i get another hc1800

mmmm, questionable. I don't know if that 85a alt can charge both batteries fast enough for the current draw off .5 ohm.

battery is fine, your alt is the problem. your voltage will just vary wildly (like mine does in my civic). I have a 2000wrms amp with an hc1800 in the back, yellowtop up front and small alt. I get no dimming at all, but when the bass is hitting the voltage take a hit, then goes back up, and back and forth

You only have one batt underhood?

Itd prolly be fine

My take is you should add a second hc 1800 in the rear for the sundown amp...

and as soon as you can upgrade that dammm alt to a bigger and better one.......

Aloha
