 Pioneer DEH-P20 LED dims with bass?

I have this radio installed in an 89 Bronco. This radio has a selection for loud 1-2-3 an equalizer (which I keep on custom) and say's it's 45 watt's per channel Mosfet amp. I also have a mobile Authority 300 watt amp running a 10" M A subwoofer. If I put the radio in Loud 2 or 3 the LED dims to the beat a bit. I had the amp in another vehicle with a Blaupunkt radio 35 watt per ch. and it did not do this. I think the radio might not be getting enough power. Should I hook it up direct to the battery? anybody know what's causing this. On a side note I am curently installing some new Blaupunkt speakers. Could the factory speakers cause it to dim?

You should add a capacitor or beef up your altenator. Get a better alt. if you are going to be serious about car audio; otherwise power strains are going to haunt you for the rest of your life!lol good luck

I completely agree. Although your HU puts out 45 watts per channel, that's max, most HU's put out about 22 RMS. Anyways, you need to look into getting a new alternator to efficiently fix the problem, depends on how serious you are though. Getting a capacitor will help with the dimming lights, but it won't fix the problem, only hide it.

It could be that are wire somewhere in the system is touching metal. It could also be that one of you connections is bad. I used caps for one of my head units cause I couldn't find my butt crimpers and that was the problem. I used butt crimpers and the problem went away.
