Easiest way is to use another source unit. If noise is still present then your hu is fine. If not hu is at fault. Could use a home audio receiver to test this.

Sounds to me like your head unit has an issue. A bad ground will not necessarly cause distorion. Maybe a source of interference or poor electrical voltage though.

Resistance across your dmm leads should be zero, no resistance. Are the batteries in your meter good? Are your dmm leads properly connected to the meter? Which dmm that you have? How do you have it set?

Good stuff dbsupra, thanks

It will perform great on less than rated power. The more power you give out the louder it will be BTW Z.3 specs are similar to Z.2 specs. Z.2 specs shouldnt be hard to find.

Your dmm isnt reading correctly

Best way to get help is to email Sundown Audio.

Thanks for posting this. Some guys obviously do not understand that this is not a 1/0 vs 1/0 thread.

The battery is mounted. Hard to see it in a picture. The battery is mounted under the sub enclosure. I want to kick myself in the ass for not designing an enclosure that allows me to use the spare tire well for the spare tire Major design f'up on my part. Plan of attack: 1. Mount amps. 2. Fix roof brace issue

Bumping for pics of the 12" in doors

Looking good. Keep the pics coming!

more pics of what lol ? Just random shit, he don't give a fuck. Take a close-up of every capacitor on that amp. LMAO! Gett'r done!

We need more pics!!

They can almost be considered pets lol. We have a better chance of seeing deer when we look out a window than not.

I started working on a battery box for my rear battery. Not finished yet.

Thanks. It has been holding up well over the year I had it like that.

Just about any of those would sound great in the right install. I put my money on Z.3

Can never have too many voltage meters After I am sure the P99RS is reading right I will more than likely remove the other one. Did you have an issue with an idler pulley setup you made?

I made a little shelf for the voltage regulator to sit on. I welded it to a factory bracket then painted it with rubber undercoating (top and bottom) I integrated a 88mm idler pulley into the factory alternator serpentine system to increase alternator belt wrap. Here is a pic of my previous install. I made a fake faceplate using the factory radio face. I wanted to change things up a little. Crutchfield sent me an install kit with my P99RS but it was cracked. I removed the fake factory controls and used the bottom tray. I also relocated my voltage meter. The P99RS has a built in voltage display but I wanted to used another since I am not familiar with the accuracy on the P99RS voltage read out.

12" is the doors!!! Did you guys read that?!!

Looking great! Are you covering it or painting it?
