Amplifier Issues

[ImmortalFreak 10+ year member]

So I was recently having problems with my headlights flickering and even my head unit and my Cadence ZRS-C65 turning off on a couple different occasions. Well, I assumed it was a bad ground, so I regrounded the amp and now those problems appear to be fixed, but I am left with this next problem:

Whether or not my RCA cables are plugged into my Cadence amp, when the volume on my head unit is turned up 3/4 volume or very close to it, it causes the Cadence amp to cut in and out despite the gain setting being

I have an 8 AWG wire running to my 4-channel amp which is powering ID CTX65's and a 4 AWG wire running to my Cadence, which pushes two ID10D2v3's. Both power wires are equipped with the appropriate size inline fuses at the battery.

So I guess my questions would be 1) Does this represent a possible grounding issue with the 4-channel amplifier? 2) If not, would running two seperate power wires from the battery (which is what I've done, seeing as I bought an unfused distribution block... I will eventually grab a fused distro, but in the meantime I just want to listen to my new install haha) rather than one wire to a distribution block cause this? 3) And if neither of these, do you have any suggestions? //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Thanks in advance, I'm not sure what I'd do without youguys! In the meantime I'm going to go ahead and find a new ground for the 4-channel just to test it.

Could be grounds, battery could be getting old alternator could be wearing out.

Have you done the big 3 yet?

How did you "tune" your amp?

I have not done the big 3 yet. Gonna be taking care of that this weekend when I get paid. I have regrounded the 4-channel to the same spot as the Cadence and checked the spot with a DMM and I don't show any resistance, so I'm assuming that's not it. I also made sure to charge the battery all night to make sure everything was good with that, and it appears to be alright, though maybe I should get it tested anyway?

As far as tuning, I have everything on the lowest except the LPF (~120hz), and gain (sitting just over 1/2 right now).

I was able to go to work today and play everything louder/better than it has sounded since I first did the install, though I know it is definitely not even close to what it could be. I ran the volume at 25/40 the whole to/from work and didn't experience ANY problems at all, though once I start getting closer to 30 (75% volume), no matter the gain on my Cadence sub amp, it starts clicking like it's turning off and on and cutting the music in and out.

I also hooked up another vehicle via jumper cables to my car and tested that, too, and it didn't make a difference.

Try a different amp if you can.

I've had the subs on that 4-channel before and never had any problems, but that amp also supplies 1/3 the power of my Cadence. I'm gonna hook it back up tomorrow and see what kind of results I get.

are your ohms right
