Clarion Line driver/EQ dimming...

[ViolentAudio]

I have an Alpine CDA-9886 and unless you buy the Alpine DSP you have just a 2 band EQ/Q settings in the head unit. So I buy a Clarion 7 band graphic/eq line driver from a local shop for $140. I installed it today and it sounds real good, but when the bass hits hard the lights on the EQ dim big time. I am sharing the same (factory) power and ground as the head unit and think this may be the culprit. The head unit lights do not dim at all. Just wondering if there are any other explanations. Thanks.

nobody could tell you exactly what the issue is, but run a better power and ground separate from the oem one and you should be fine

try running a dedicated power wire for it

so if i use a seperate power and ground i should ground both the head unit and line driver to the same spot to avoid a ground loop right?

run a 10 gauge to the dash, distro and run both hu and eq from that.....ground can be common

what do you mean ground can be common?

common = the same

ie ground at the same point

common = the same
ie ground at the same point

okay i gotcha...but it should be a direct chassis ground right? not through the wire harness/factory ground right?

don't use any factory wiring

i just went out and checked my wiring and see a power/ground for my cigarette lighter that has a 15a fuse on it, which is the same as my H/U fuse rating....was wondering instead of running a dedicated power/ground for the head unit and line driver if i could just use the power wire for just the eq off of the cig lighter with a scotch lok connector since i dont ever use the cig lighter anyways, and redo the ground on both H/U and EQ to direct chassis ground....
