how to step up my voltage to optimal?

[sound giant 10+ year member]

I was wondering how i can get 14.4v that my amp needs to run at its best. i have monster cables and a 1 farad cap to my mtx 942 amp.... the cap display never reads over 13.3v and sumtimes as low as 11.5v...how do i get it up to 14.4volts???

your car was probably desinged to only run at 13.8 volts. (GM?) Your factory wiring isn't designed to carry much more current than that. You need to get a different regulator for your alt to allow it ro run 14.4v instead of 13.8v.

My Trailblazer idles @ 14.4 - 14.5 no audio load.

With the amps outputting 2kw+ (into 1.5 & 4ohm) she floats around 13.6-13.9 @ the D-block.

It's a GM.

check autozone or one of those places.. you may have to go to an acutal alt shop or one online. There may be some auto mechanics that can get you the right one too.

is 14.36 a good idle for a stock car?

Well yea thats pretty close to 14.4. But another thing you should see is how much the voltage dips when you play a song that hits bass really hard. For example my idle is at around 14.7 and when bass hits hard it drops to 14.2 which is still good. Basically as long as you stay above 14. I know some amps have an extra feature that makes them shut off when it goes under 12 volts or so. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
