HU = AVN6600
Installed Rockford Punch 1320 & MB Quart Speakers.

Removed the stock JBL amp and sub.
Tapped into existing wire.

ISSUE = a hissing sound or air sound exist at zero volume.

Turn on higher volume and it still remains.

HELP ...any resolutions?

Should we rewire the entire car? Is the hissing sound coming from the JBL sound system controller infront of the passenger seat?

Do you hear the sound regardless if the engine is running or not?

So it gets louder as the volume is increased?
 
the annoying hisssing is still there even if the engine is Off. you can hear it a tad more with the engine off.

I'm afraid i might have to rewire everything. but if their is another way out, i would prefer to try that. rewiring is a pain but atleast you get to add monster cable for more better sound.

hmm,
Check your grounds, make sure you have your power and RCA's away from each other.

Where are your gains on the amp set at?

Does the sound go away if you unhook the RCA's?
 
thanks for the advice. I will work on it this weekend. I cannot access the AMP since it's now locate in the area where the stock sub is at.

Once everything is close, it's a pain to take apart.

Would tapping the stock wire have something to do with the noise as well? I heard the IOC or IO2 is digital and maybe causing the humming sound.
 
I'm in the process of replacing my entire system (which was also the 10 speaker JBL setup). Everything I read here (which was a lot) and what two separate installers told me, indicates that you CANNOT use the existing wiring from the JBL setup. Why? I don't know exactly - maybe someone can explain that, but my understanding is that all new wires have to be run...

Rewired everything but the noise was still there.

Recheck the gain, and lower down. The noise has reduce after the gain is lower.

So, tapping pre-existing wire is OK.
 
I believe this is engine noise. Do you get it higher as you rev up? Check your RCAs, unplug your RCAs and if the noise is still there, let us know.
 
I recommend not using Rockford amp for running a system. I will return my amp and get a new one this week.

My system is missing some sub. I can live with it for the time being until I figured how I can integrate the Sub.
 
Has Fosgate gone down in quality? I am running an old Punch 200, the amp must be about 10 years old and still producing great clean sound.

In the early 90's fosgate equipment was competition grade gear. You had to go to a specialized car audio shop to get it, and you paid for it too.

If you had Fosgate gear, you were wanting to compete, or just wanted the best. For example the old Punch 150. That amp is a classic. Your punch 200 is good too, it was maybe the last amp they made before they started selling their stuff in places like circuit city or best buy.

They've become a mainstream company now, and many have been turned off by this.
Their equipment is still 'good' but not like it was. There just isn't anything special about their stuff anymore, because anyone with a couple hundred bucks can say
