HU dim when i turn the lights on ?

[gekko]

When i turn the lights on my Head Unit dims (like the clock does) ...
how do i fix this , i just installed a Rockford fosgate RFX-9220R , on my old sony this has never been a prob

you didnt tie it in ith the dimmer switch? could be just a power drain. either check your alternator (could be dying/not putting out enough juice) or it could be that you need a cap cause with the lights, subs and HU everything is just not getting the power it needs. a cap for the amp/subs might allow more juice to go to the HU, lights and everything else

i connected it to the .. whats the name .. that standart connection that fits almost all players is it iso ?? well never had that problem before but i will test it when both amps and crossover off

Maybe you connect the Dimmer ligth wire from the honda radio harness to the head unit, my pioneer has this feature, when is connected and turn the car ligths on, the head unit ligth turns darkness. You could try whitout this wire connected.

My Alpine Head Unit dims at night when I turn my lights on, it is supposed to do that because it doesnt need to be as bright as during the day.

But I know with mine there is a setting where I can turn that feature off, or control it manually... Try reading the manual that came with your deck, it should be in there.

I would go with what hash man says. come to think of it i had a HU that did that. wasnt alpine though.

my pioneer does that, so does the pioneer in dad's other truck... i took it as normal, as it had a wire to hook up to the dimmer switch in the car, and i hooked it up to it... makes it easier to concentrate on the road at night, so it's all good in my opinion

Gekko, the Rockford deck most likely has an orange or orange with a white stripe wire on the back. That wire is most likely connected to the red with black stripe wire iin the dash. Cut it and insulate it. This will fix your problem.

Welcome.

Good call catalin, but its a shame he had to tear everything apart. My JVC deck has a dimmer on/off option...the rockford probably does too. I dunno I tend to be anal about that kind of stuff. I don't like to cut wires to fix things.

[catalin]

I doubt the Rockford has that feature. We've sold a couple of their models last year and they really quite plain systems.

What JVC model do you have??
