still getting voltage drops.

[MitchZ 10+ year member]

I finally got my zx2500 fixed. But I'll be running it at 4 ohms. 1200 rms.

I have a kinetik hc2400 in the trunk and 0 gauge all round. I still get significant voltage drops and dimming. I don't have big 3 because I'm not good with electrical under the hood

Will that fix the problem or do I need a isolator

Big 3 would help a lot.

gains are set extremely low too. Like 1/11 of the way on. Bass boost 1/3

big 3 could eliminate this

even doing the grounds under ur hood will help. i wasnt able to do the power wire from my alt, only the grounds and it helped.

id goto knukonceptz.com and get some 1/0 rings and however many feet of wire you need. probly only like 5ft for the grounds. do you have 2 runs 1/0 connecting the front and rear battery. one for postive and one for negative? also how many amps is your alt? and are your testing the voltage drop at idle or reving to 2k rpm. how much is the voltage actually droppign?

What car or what size alternator Brah? Big would help some as others have said.

I have one power wire going from front to back. Batteries are grounded to sanded chasis. zx2500 is grounded to battery and 4 ch is grounded to chassis. It's a 1995 mustang so I think the alt is 130 a. I have a battery voltmeter in the dash and it looks like it drops 1-1.5 volts and keeps going down on constant bass songs like da blow. On other songs it's okay. Like party like a rockstar.

You set your gain based on calculations not nes on where the knob position is, also I did the Big 3 and it helped alot but I still get some drops with heavy bass when my lights are on (usually when Im stopped at a stop light)

meh, lights dimming is a part of any (at least) decent setup

Big 3 FTW...//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i have an 2001 Audi tt and was running 1500 watts @ full tilt and had major light dimming issues, i did the Big 3 and it didn't help much at all, added a second battery and problem was solved... then moved up to 2200 watts and dims again although not bad at all.... point is dont expect it to solve everything, if you are even considering expanding the wattage go with second battery (plus Big 3)

calculations as in voltage usig a dmm to the speaker out puts?? At 35 hz tone??

I already have a hc2400 in trunk. That's more than enough for 1200 rms

understood didnt read too carefully my bad

I probably have to set my gains because they're set now from trial and error //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
