I have my 3 amps & radio (Jbl ms8, alpine & JL Audio) hooked up to a 1 in 4 out JL Audio, fused power block. 2 gauge wire going to the battery & 4 gauge going to the various components except the radio. That's 14 gauge or there of.

I have all of my grounds hooked up the exact same way but the one ground wire is in the ground post located on the driver's side wheel well.

At any rate, when I turn on the car (unlock the doors etc), I can hear what sounds like a chatter of sorts coming from the passenger wheel well/ battery area. I'm not sure if it the relay I have hooked up to the back up camera or the actual amp power wire hooked up to the positive post. All is fine. Everything works as it should and that's the only time you hear it. Ir doesn't even do that 100% of the time, but more like 75% of the time.

I have the power 2 gauge power wire crimped with a gold ring terminal & I slide it under the red power block onto the positive post. It's a relatively new AGM battery (about 18 months old). I didn't go cheap on the wire. All of the wire was rated 4.5 stars and above on Amazon with hundreds or more reviews.

Any ideas?

I'm not too worried. Like I said. Everything works. I just don't get all the clatter....

If it only happens when locking / unlocking the car, it's probably the relay. I have a relay that controls some aftermarket lighting, and is switched by a light that fades in/out when locking/unlocking doors.

When the signal wire "fades" in/out, the relay makes a weird noise. But once the signal is on/off it's silent.

If I manually turn on the switch (no fading), no noises are heard.

Hopefully that helps!

I wonder if I need a better relay?
