doesnt make sense
ok so i had 3 10w3v3's running off an arc audio KAR 900.1 in a sealed box
bass use you dim the lights slightly at full tilt now ive switched to a ported box 4.3 cubes at 36hz and the lights dim at half tilt and if i really turn it up the volt meter goes bananas lol im thinking i should go over the wiring again anyone else??? |
Double check your sub wiring. Did you move the amp or change any settings? Check your gains, bass boost and your grounds as well.
|
your alternator is dying.

but i still stand by the previous post. your alternator has progressively gotten worse at charging the system. |
If nothing changed, the subs in ported box became more free with movement, and started to demand on the amp more to keep control at higher excursion. So the amp started to draw more power to convert more power to the subs. That is all.

Back the gain down a little, you may be driving the amp a little too hard.
You dont need to drop it down all the way, just a little to get rid of the dimming. I set my gain with an O-Scope, 40hz tone with a 10dB overlap. Oh and how's that box working out for you? I wouldn't mind hearing it. |
