Hey guy's my setup i got now consist's of this.

HDC3 18" dual 2 sub

MD.2D Sub amp

Massive Ca100 frontstage amp

Stinger Spv70 upfront

Duralast deep cycle dual purpose batt

Dc sound lab 2k batt also

Alpine 9887 H.u.

All 1/0awg

Big 2 done right now lol (still need to do pos from off alt fuse it to pos on pos terminal).

Im getting a bad voltage drop like headlight dimming bad voltage drop were talkn. Could it be because i don't have the 3rd BIG 3 wire coming off pos side? would that do it? Thanks for help guy's.

Will do CrX thx for the help bro. Do you think the BIG 3 would effect it that much. I man driving i can even go from a 14.5v with headlights on as soon as i get a nice pound like deep not even full tilt i will get headlight dimming and also voltage will drop to like 13.5v then after the sub done hitting will shoot right back up to what it was.

ive only got big 2 done also lol, but my headlights dont dim, and 13.5v isnt a bad drop

what size alt u have?

 

[audiobahnuser18 5,000+ posts]

Stock alt so 130amp , still shouldn't really effect it with the batteries what i been told. Im also though saving up for a M.L.A. from chris i know that will deff help.

Its funny how in the wintertime there are all of these light dimming/voltage drop questions.

If you haven't completed the Big three then to your electrical system it doesn't even see the extra wiring. Current flows in a loop and you haven't completed that loop yet so its not the lack of big three.

Check ALL of your grounds. How old is the ALT? How many times have you deep cycled the battery?

Battery is new from autozone bro actually first time it's been wired up. The alt is good though had it checked and it's good. Hmm....i''ll go through check all my grounds again. Im gonna maybe re-check my amp gains also cause my friend set em for me. I just now thought of that.

Friends Don't Let Friends Install Car Stereos

Its the MECP way....

I didn't let em install it bro. He just set the gain's but im gonna go through re-check em all.
