Loud pop, pink noise playing through speakers

[04murdalanche]

Hey guise.

So earlier I got in my truck, started it and POP my subs hit really hard and it scared the living shit out of me. Immediately shut the truck off to find the problem, all connections were good, no stinky, no fuses popped, amps turning on, etc... Turn the truck back on, and this pink noise sound is coming through my speakers now. Never happened before. Still plays music but you can hear the noise in the background it's about a 3/10 on loudness. Not sure where to even start, help me pro favor.

HU is a Kenwood x994 and 4 channel is a alpine PDX 4.150

Hmm, Id look at the Remote wire,and see if it is making full contact..How many things are you running off your one remote line?

I have 10 gauge running to the back, then speaker wire spliced into it so I could have a turn on for my SAZ and PDX

As I said though all connections are GOOD

My truck was doing that when turning off, and I ended up needing to add a relay for the remote line/30 amp relay..like $5 at Orileys

I think you might need to add a relay man.

Yes sir,sounded like a bad grounding issue..and when turning off the truck after I turned the HU off..POP!/Thump!

Have you checked your Voltage?

Id check to see if where you spliced that 10 up to the remote line,and see if its smoldered/melted any,if so, that may be your answer, and you will need to add that relay man

Just the remote could be doing all of that? Wow

hmm,ya, mine was fine for about 6 months, then started doing that for some reason???But It could even be an RCA touching metal /grounding out too(covered with elect. tape and worked fine)..Thats where Id start at.Well, thats what turns ON/OFF and if its a bad connection, the amp is popping on off /sparking trying to make a solid connection

Id start at the Remote line, then check/move the rcas/wiggle them to see if they are creating that pink noise..(grounding out)

Mm, weird. But I was testing out a SAX125.2 I picked up in Rockwell today so I just checked them and redid everything so I know it's tight

Yank the RCAs out of the amp. If the noise goes away it could be something bad in the HU.
