• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Anyone else have this happen?

I have two 12 inch Polk Audio subs, along with a 1600 watt amp.
I was curious if other people have this happen, when the bass hits hard on the sub woofer, for example when the volume is maybe 1/2 on the head unit, my inside dome lights dim almost all the way down, and my head lights dim a lot also.

Time for a new alternator?
what do you think?
 


Please post up what brand and how you ran your power wiring. What you hooked it up to, all the parts in the system, including the rca's, head unit, how you tooked to power and ground.
 
Move the power to the battery and get an alt rewire for the underwood relay center. Should help a tad. You'll still need a cap or extra battery I think though
 




Basically get a piece of 4 gauge wiring about 24-30 inches long. Wire it to the alternator output terminal and to the positive battery post. The factory 8 gauge wire for the alternator will stay in place. The factory wire runs half way around the damn car and is too small to power the car, let alone subs.
 
Yes, but leave the original on as well.

The kicker kit doesn't say anything about the wire or it's quality. I used Knu for mine and attribute that to a lot of the lack of issues that I have. I have zero dimming etc. But then we have different setups. Take a look at this basic Knu kit. 4 Gauge Amplifier Installation Kit Tells you what the wire consists of. How it's connected etc.
 


Run more wire to the amp first.

One four gauge run isnt enough from my limited experience.

That amp might draw over 1.6 kW, which is quite a bit for a single run of 4.
