02 April 2014 - 08:53 PM

Hi All. Im new to the forum. not sure if anyone can help me.


I have a 55 plate 1.6 ford focus.

now everytime I turn my radio up and the bass hits the lights dim (headlights, odometer light)

now this is what I have installed at present


105a brand new ford original alternator

a brand new 72ah battery silver calcium ford original

done the big 3 wire upgrade

cleaned up the grounds in boot, headlight earth, and main earths


I have a jvc head unit

A FLI 900S 4 channel amp in 2 channel mode bridged with a 12" edge sub connected to it


if anyone could shed any light on the situation.

would be gratefully appreciated.
