Speakers are whistling at me

I had a sub-contractor come to me and do it.. Im not sure whether there was a warranty but ill look into it..

Pulled the door frame off earlier on tonight and couldnt see any visible damage to the wires, but then again I never really expected to..

try re wiring your speaker connections (solder them on if u want) and as for the noise filter, the rcas connect to one side of the filter and the otherside connects to you amp

The guy who hooked the speakers up for me did a pretty professional job.. Stripped all the cords neatly, twisted the wires together, then soldered and taped them back up...

Whereas in my mates Laser the grounding is visible once you remove the headunit.. My grounding is taped up and keeps going back and back till I cant see it anymore..

I am going to re-route the cables down the opposite side but what I dont understand is why I havent needed a noise filter/cables down the opposite side, until this last fuse blew?

Ive blown fuses before and replaced them for perfect sound quality...

I think I have localised the problem..

I ran the speaker cables for the sub down the opposite side to the power/remote wires..

I plugged it all back up and turned the car on to no avail.. Still hearing static noises.. However when I removed the RCA cord for the sub (sub still had power obviously) the static and high pitch squeal cut out and music still played..

I hope this gives someone an idea of what my problem is...

are you listening to the whistle song?

Can you test with another head unit, amp or even just a spare set of rca cables?

Also sometimes noise is induced when the RCA cables aren't 'gripping' tightly where they're plugged in. This happens because the outer metal circle of the plugs provides the ground, and if this is not connected 100% then of course there are grounding issues.

Make sure the RCAs are plugged in tightly and all the way. Could also be a damaged cable.

One of the other options is, as suggested before, that the head unit had it's grounding fried (again to do with the RCA cables. The tracks could have been damaged, so if you were able to test with another head unit that'd help localise the problem.

If the sound is very constant, it could be your amp not being able to handle the power it gets.

It is very important to do base wiring correctly.

When some device receives xxx much of power from battery, it should let xxx much of power out and back to battery.

IF input > output, then where does the (input-minus-output) go???

Check your grounding too!
