I have a pioneer deh-2200ub and clarion eqs746, installed with a monster cable head unit power kit. My question is what is the correct way to wire these two things together (power/ground)? Currently I have them spliced together off of the monster cable power wire I ran from the battery to the dash, and they're also grounded together to a piece of sheet metal behind the dash to keep the wires as short as possible. Would I be able to run the grounds somewhere else, because I feel they're currently not reviving a good ground.

Should be fine. What makes you think the ground is bad? ------------- Support the12volt.com

The lights to my eq go really dim when I put the volume up 3/4

That may or may not have anything to do with grounding. What's the voltage at the EQ when that happens? Does the head unit disp;ay any similar behavior? ------------- Support the12volt.com

As far as I can't tell the head unit is fine, but I'm not sure of voltage, but they're both wired together as far as power/ground. On my cap it reads from 12-14, do u think it may be a charging issue?

It's possible your alternator cannot keep up with the load and system voltage is drooping. It's also possible you do have a bad ground, or even that your EQ is defective. Put a meter on the power lead to the EQ and see what it is when the lights dim. ------------- Support the12volt.com

I know my alt is 108 amps stock and how would I find my amps consumption? My bass amp has 2 x 30 amp fuses and my voice amp has 2 x 25 amp fuses and the kit for my deck wiring is a 10 amp

Yea here's the Model Number: #MPC P200 BAP50, It says 50 watts. Maybe having the eq and hu wired through this is too much load on it?

Is this a pre-amp EQ? Do you have speakers connected to the radio's speaker wires?

The eq is a clarion eqs746, and the reason I have the eq is because my deck only has to 1 set of outputs, and I needed 3 sets(front,rear, and sub).

ARE THERE ANY SPEAKERS CONNECTED TO THE SPEAKER WIRES OF YOUR RADIO?

No the speakers are hooked up to my voice amp

I checked my cars voltage with my volume up 3/4 and my system held around 12.8 to 14.3. The lights practically turned off on my eq but did not shut off. So would that be a ground issue?

You need to check the voltage AT the eq during the dimming.
