voltage and capacitor

What are the oa's u speak of?

As for your voltage problem, the culprit is your battery. I had the same problem. Replaced my battery and now 14.4 volts at the amp at idle.

Did u just get a new regular battery

On 1200 watts. 3 Level 2s

have your battery put on a load tester (most auto parts stores will do it for free)... doing the big 3 will almost certainly fix your issue tho, as i dont see it being your battery... just have to remember, that no matter what gauge wire you run back to your amp, your stock wiring that the big 3 replaces is very small, at best... sometimes its down right rediculous... but then again, cars arent designed from the factory to be pushing that much current... which is why the big 3 is so important

How come only 3? they are 300 rms a piece be perfect on 1200rms

Dont forget voltage drop and box rise. You will never see 1200 watts. Unless you get a big time underrated amp.

Box rise?

Lol nvm I got u now ur talking about the battery

The regulator is keeping ur voltage at 13.5. Not much you can do, unless you want to change alternators to one that is regulated higher.

^^^ This

Depending on your car you may need to bypass the factory regulator and add an outboard one. I needed to with my Jeep. Factory "brain" only charges to mid 13V range.

What exactly is box rise?

Certain tones in music change the ohm load the box sees. From what I have experianced larger boxes rise more then small. Maybe one of the savy guys on here can explain it better. i just know it happens but I dont know why
