Can a bad power wire cause bad voltage drops at the amp?


Recommended Posts

Can having a bad power wire cause really bad voltage drops at the amp?

I've been having really bad voltage drops, and I don't know why

My electrical is a 55-100 amp stock alt, Deka G34, Big 5 done(Yes Big 5), and I'm only running 900 rms at 2 ohms(amp is rated to take 60 amps, so it's actually overrated)

My power and ground wire is a Cadence 4 gauge I got from a kit long time ago when I was starting out car audio

Here's some pictures

mine goes to about 12.8 13 when under load i have 4 batts but i know i need a bigger alt throw another bat in back and what are your speaker wires running power n ground too

Well, you are running alot more power than me, so I understand your need for a better alt

Speaker wires are 8 gauge ofc Audio-Technix

Power wires are Cadence 4 gauge wire from this kit I got a long time ago

wouldnt this mean u need more battery?

I know it probably does, but I want to make sure it's another problem

55-100 amp alt??? You mean you have 55 @ idle and 100 max. That´s a tiny alt, if your car is running and use some voltage for his own electrical and you draw on music

50-70 amps, so it realy start to suck you batt quick.

It looks like itaht you have the 90 $ batt out of the offer in the "Hot-deal´s" section, add a second batt. Or get a 150 amp + alt, + depend´s more what you want to do in the future

Yeap, still using it cause it hasn't blown or anything

Friend of mine told me that it could be my power being too small causing it to drop badly

Might as well save up for it then.

Are you holding the throttle at about 2,000 RPM? You do not get full alternator output until you are around 1800-2500 engine RPMs. It might only be able to put out 40 amps or less at idle.
