hey folks,
I hope someone can help me with this speaker noise.
I tried replacing the rca cables... using different amp.. but didn't work.. the noise
sitll remains.
I put my ground wire to where the spare tire bolt used to be. of course I shaved it off untill I saw a mirror shine surface.

Could this happen from the hu? I am using the Alpine IDAx 200.
My amp is Alphasonik pma 4150A 4ch bridgeable.. and speakers are Infinity reference component speakers.

OR, could the fuse that I am using for my amp be a problem for causing this noise??
When I look at the manual, it says "none" for the power fuse while other models have specific numbers for the fuse. Right now I am using the fuse that came with the amp wiring kit whcih the number says 100.
Could this be a problem?

I really need some help. I don't want to spend more money into this by taking it to a local shop.

*edited* I am doing a tri-mode. channel 1 and 2 for my speakers and 3 and 4 for my subwoofer.

 

I would double check that ground...

The ground for your amp should be a completely brand new hole, not a reused one. Make sure you grind away ALL layers of paint and rust inhibitor and then drill the hole. The threads of the screw (preferably brass) need to make solid contact with the sheet-metal - that's the grounding.
