Issue I can't figure out....

[GiAnT4LYFE]

So my setup is a DC 2k pushing 2 Level 4 12's with a DD C4A pushing my Massive Audio CK6's and I have an xs d3400 in my trunk that this is all connected to. I've had this setup since last August and have really had no issues......until now.

A week ago this past Wednesday I received my DD1/CC1 combo pack and set my gains, cross over pts, and checked head unit level on my setup. This was all done with speakers attached and had to be done through the amp, meaning using the amp ground and output positive. When I went to pull my RCA cables off my C4a, the gold outer ring from the amp came off with it. I pulled the amp out of the car and had a friend re-solder the gold pc back on.

After we put it back together, everything seemed to be fine. But a little while later the amp went into protect mode. I shut off the deck, waited and turned it back on and everything is fine. Going forward from this point though, if I turned up the volume and the bass hit too hard it would go into protect mode. So I called DD and ordered a new RCA input and installed it into the amp. I also noticed that one of my RCA's would "wiggle" a bad connection, so I ran a new set from the back of my deck to the amp (knu koncepts).

I was hoping all this would fix the issue, but it still happened just not exactly like before. I have double checked my grounds from the amps and they are fine, back to the battery negative in the trunk. I don't believe it's voltage drop.

This morning on the way to work, the front speakers started getting a little fuzzy/feedback ish and I turned it off for a few and when I turned it on it was fine again.

I am lost for ideas now though and am hoping someone can help guide me to troubleshoot this....

Thanks SMD fam!!

Umm, is the solider connection clean?

Did you check your ground connections...I've done this a few times when moving my amplifier back in the days. I moved the amp, my ground connections came loose. Also check for corrosion around the ground.

The solder connection is very clean. I had my IT dept do it with me at work and they are a great little personal "geek squad", lol.

My Ground connections go from my amp to the negative terminal on my rear battery (xs d3400). I have runs of 1/0 pos and neg going from front battery to the rear xs 3400. All of the ground connections have been gone over and are tight. Also corrosion isn't an issue with the way its ran. Like you though, this was one of my first thoughts.

I just installed my Pioneer AVH 4400bh, so I'm going to pull out the DD1 and CC1 and set everything up again....fingers crossed that I can figure it out.

Umm...big 3 upgrade done?

For my system, even though it's only going to be 2k rms, I'm putting two batteries in the trunk spare, putting a bus bar and wiring both neg ends to the frame...is that an option for you?

Have you checked for voltage drops and shit?

I haven't self with 2k rms but could it be voltage being that you set your gains with a dd1 and they are now higher? Giving you more of a voltage drop than I was before? Sorry if that's a tad confusing

Big 3 is done...1/0 welding cable.

Newbie, I would guess what you are saying is possible and it does make sense. Like I said, with the current electrical as I have now, there were no issues until last week. I had always relied on my car DIC to give me my voltage and hadn't installed a volt meter at the amp. According to my car, I am never below 13.7, and usually over 14. Obviously I know this may not exactly be what the amp is seeing, but with no prior issues I figured I was good.

Thanks for the ideas guys.

And I will say that I'm willing to spend what I need to to correct the issue, I just need to figure out what the issue is, lol.

When yuu reset your gains with the dd1 did you turn the gain up more thOugh? Yeah I have been told the stock one with the car is off by far and as you stated doesn't state what the amp is getting

Called Ric from PCA....gonna redo the DD1 and see what's up.

I haven't moved the gain since setting it and literally just installed the new deck an hour ago. I'm at work and haven't played with it yet. I used the -5 to set the amp last time for the front stage, now I'm going to use the 0.

In order to upgrade any electrical at all before tomorrow's show, the only thing I could think of doing is buy 2 yellow tops and throw my 3400 up front. Time to find some 1/0 and terminals.
