i do a lot of that

zoo how do i test it

first jump it? then what let it run for 20 mins to charge the battery then what?

Battery sounds deep cycled. Won't hold a charged once a battery has been deep cycled

why not just get a capaciter or however you spell it to combine with your system and it wont affect your battery so much

i jumped it
measured 14vs with radio/ac/ light off

i had 1v drop when i turned on the radio to max volume and ac and light on

so idk 1 volt should effect it righ

You "should" be fine.

According to avoids dumbass when his sys was bumping his shit would drop to like 10 or 11 volts..

if you'd seriously like to get rid of voltage problems get a higher amp alternator and an xs battery

there is nothing worst for your alt then a weak battery, 2 amps off a stalk alt will fail once it starts to sound good (99% of the time)

i hooked the amps back up and let it sit a day started right up idk what the hell was wrong with it.

implying cheap batterys last 5 five years.

maybe it's just Arizona but they don't last that long here

That is true...off my dick.

Id have roughly 12.3volts then it'd drop into the 11s (with the car not running).

Old saying goes, never let a mechanic install your electronics, they are clueless.

Weren't you the one arguing with me about the alternator charging voltage? Ill back up what I said 100%.

Should be mid 14s, if in the 15s, your alternator is stuck in the "on" mode if that makes any sense.

indeed
