Sub making odd noises.

[GGnz]

It seems kind of wierd but lately I keep getting some form of feedback on my sub. Random low bass notes that arn't in the music!?

Why could it be doing this. I havn't checked the wiring yet but its been fine for about a month now...

[GGnz]

Forgot to mention but, you can actually only hear it when you have the stereo on quiet.

[Snoozin]

By "feedback" do you mean a hum? And is it when the car is running?

First things first, check ALL your earth points - ie. make sure the amp is properly earthed, the h/u is properly earthed, and the earth points for both the battery to chassis and engine.

[GGnz]

Not always a hum. Only occasionally and seems to be when the car is running. Will check em tomorrow.

[Alex B]

Only when car is running?? Yep more than likley an earthping problem.

[GGnz]

Grrrrrrrr! I hate sounds!

[Alex B]

Well do it once do it right i say , Bigger earth wire wouldnt hurt, 8G a bit small and find a decent earth, if its a painted part of the chassie, remove the paint under the earthing point too.

Probably have the gain wound up too high for a start.

[Mr.Phreak]

But winding the gain up makes it louder Guv'na!
