Right guys, I have a wee problem with my tunes. This is a long one too.
When I first had my aftermarket HU installed (into my Mk4) everything was fine, I could turn my tunes right up untill the speakers would distort (becuase they were the naff factory ones).
Then out of nowhere the sound began to pop and go really quiet. It faded in and out now and again. The way it went off was as if there was an electrical short somewhere as the HU display would flicker a bit when it happened. So asked for advice and people said it was the speakers.
So I put these in the front
And put these in the back doors (5dr
As adviced by a local Auto Electrician as I dont have the funds for Comps and Amps as yet. (the factory tweeters are still though)
So thought that would have sorted it. It didn't, they still go off, but only now and again. (on the way to work this morning all was fine????)
Next thing I did (shamefully) was pop into halfrauds on my way between jobs and asked one of the guys in there what he thought it could be. Managed to show him what happens and he reckoned it was the speakers on the left. As when it was faded from left to right, it only happened on the left hand side. As he said it was the speakers, I then told him that they are brand new, then he decided it was the speaker wire. But this was a total contradiction in my opinion, becuase if the right hand side speakers are fine with the standard wire, why should the left hand side be any different. So he was adamant it was the wire and let me know "we sell some good wire" so I came to the conclusion he wasn't very helpfull and only wanted to make a sale. Advice from my local Auto Leccy was that speaker wire makes no difference, I bought some thick wire once and got laughed at and told the wire purchased could power an electric drill and wasn't needed for the door speakers, he reckoned it just looks good and doesn't make any difference to sound quality and stuff like that.
The sounds are fine at half-way volume then occasionaly when turned up it does the above. After going to Halfrauds last night, I was at work and tried to show my mate what happens, but low and behold it didn't happen. I had it up to full volume and no pops/crackles/fading, nothing. Then later on when I went for a drive it started again. Managed to show my mate and he reckoned it seemed like an electrical thing. I'm going to take the HU out this afternoon or tomorrow when I'm off to check the connections in the back, just wondering if you guys know of anything else it could be???
Thanks for your help and sorry for the huge post.
This is my HU too
