Default dimming lights

Have a problem with the lights dimming on my car. When I have the lights and stereo on, it dims when I press the wipers, brake, turn signal, or turn tight. I have an aftermarket radio with an EQ, no subs or amps, plan on installing a 500w and 12sub. The gauge goes down a little when it dims, but doesnt go down much, the rest of the time it stays around 14, sometimes a lil higher. I just had the battery and alt checked at Advanced and everything came back good. When I searched the problem was fixed with a new alt, but mine is good. Do I need a bigger one anyways? Any ideas as to what to check for next? Battery is nice and clean, and tight...

Thanks

This might be a tough one to nail down. You have less components and gizmo'* than an SSE or SSEi, so a stock 105 amp alternator should do you just fine. I'd be more tempted to chase down grounds. Try the one under the carpet near your hood release, pull it apart and clean it, and also chase down both ends of each battery cable. Pull apart, clean, put back.

Start there, and let'* see what you come up with.

I did mess with the ground by the passenger side kick panel, I check it and has good contact and is tight. I will check the under hood connections later today. I have a feeling this is going to be one of those never ending problems... Thanks for the idea

yeah, i have the same type of problem, but it started after I added a 10 disc fm cd changer. Mainly I think I caused it by where I added the 12 volt constant, and I'm hoping that if I switch it it will work fine. But my lights dim when I hit the brake and also flash erratically (parking lights, atc, radio) especially when the bass hits from the cd changer... but it should be fixed soon. So check your radio connections to make sure they are good connections, power and ground
