9volts

[NegativeEffect1 10+ year member]

the gauge on my truck reads 9volts when it hits hard, my question is if i run another 1000 watt amp will it kill my truck? also my lights dim insanly and all the amps i have are running off of 2.4farad caps...time for new alt and big three?

one thing that is sorta odd that i notice with my 2 jls hooked up my lights barely dimmed at all but with one TDX hooked up they dim like crazy

9volts..thats extremely low man

The big 3 ain't going to fix that much voltage drop. A few tenths of a volt.....yeah, the big 3 would help. 3V+ drop and the big 3 will barely make a dent in the problem.

Ditch the cap 1st. Upgrading the big 3 is definitely a step in the right direction.....but if you are seriously dropping down to 9V then you definitely need to upgrade the alt as a minimum. Also, I'd suggest not turning it loud enough to see that much of a voltage drop in the meantime because that low of a voltage could potentially damage your amp and/or your truck's electrical system.

hmmm, guess i should turn the bass boast down a lil until i get those things fixed

soo New Delco-Remy CS-144 type, 250 Amp Dual Rectifier with OEM Voltage Regulator + Big 3 upgrade + yellow top bat. = //content.invisioncic.com/y282845/emoticons/veryexcited.gif.c26a15f316d23068607f36ddacd7a7ab.gif (prob. solved)

**** it now i need like $1200 for another amp, alt, bat, and if i decide to be lazy, install

My voltage drops used to get down to 10 volts...when I only had 600 watts rms total. Now I never fall below 13.4V with the big3 (1/0ga) and now I'm running about 1200 watts. Original stock wiring had to be like 10ga prior to the big 3.

ok i was reading the volt meter wrong...it was more like 13-14 volts...i feel stupid

I was gonna say those trucks have some big alt.'s in them....

 

[NegativeEffect1 10+ year member]

yeah thats wut u was thinking too, so now do you guys think i can run another 1000 without changing the alt? im gunna get the big 3 done when the new amp goes in

 

[NegativeEffect1 10+ year member]

does anyone think ill be ok to run another 1000watt amp without changing alt but doing Big 3? now that i realized its only going down 1-2volts

Only one way to find out... try it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The big 3 won't do much unless your stock connections were badly corroding or had no surface area on the connection...the stock wiring was meant to handle whatever capacitance your stock alternator can possibly create....I suggest getting a new alternator, battery, and upgraded alt/battery wiring with thicker gauge wiring- that's the only suitable solution to your problem IMO.
