Dimming Lights & Distortion Issues

Dimming Lights & Distortion Issues
I just installed an amp and a sub in my car...
Kenwood KAC-X812 - 919W @ 2ohms
Alpine SWX-1042D - DVC - 500W/coil @ 4ohms
4 gauge wiring
I used the jumpers to run the sub in parellel and I am running the amp at 2ohms.
When I get the sub at about 40% my lights start to dim if I turn it up a little bit more, I get a lot of distortion from the sub.
How do I fix? Capacitor? Alternator?

A 900 wrms amp will draw about 50-60 amps continuous. Average car needs 80 amps, with lights, a/c, ignitian, rear defrost, etc. + 20 more for charging.
If your wiring is up to it and your alt is 150 amp, you should be good to go.
I have 140 amp factory alt, 0 ga. wire and 3F cap. I don't play it loud while i'm using all the electronics in the car, or the voltage drops.

Its been shown that running RCAs next to power wire does not effect noise...That is an old myth IMO... (an amp can't pick up fields caused by DC current flow!)
the noise we are worried about is caused by alternating magnetic fields....
If your noise went away when you moved your RCAs it was more then likley for some other reason...

I'll let you know how it works out.
