Distortion

[Techchild 10+ year member]

Hi,

I have a 95 del sol, I just wired up a crunch pzi100.4 to my speakers with 4g power wire and 14g speaker wire all stinger hpm series. The problem is depending on how the rcas are set up it's either really quite or alot of really loud distortain even with the volume on the head unit turned to 00. I tryed changing the direction of the rcas no luck I tried changing from left to right top to bottom also no luck. Does any one know the solution to my problem?

oh and that is with every thing turned down. When it is real quite and you even touch the gain at all I mean just putting a screwdriver on it, it goes real loud distortion

How can you tell if it a bad ground?

I have some pictures of the install.

I'm using the factory ground should I reground it?

that would be a very smart thing to do... IMO

does it do it with the car running or with it off?

did you take the ground surface down to bare metal? because it doesnt look like you did...

it does it when the car is in accesery when the gain is all the way down. It only does distortian when it is in the first key position when you touch the gain.

Two seater and that is a metel wall attached to the frame.

Also found out it is the headunit rca output making all the noise.

And my mom threw out my reciets //content.invisioncic.com/y282845/emoticons/mad.gif.c18f003ab0ef8a0d9c27ca78d77a6392.gif

check the connections inside your amp were the rca is soldered to the board. i have had the same issues and it turned out the solder broke and a quick touch with a hot solder iron fixed it.
