Hi guys
When I start my engine up, about 3-5 seconds later I get a massive thump in one (I think it's only 1) of my subs. It's fine after that and works perfectly. Has this happened to anyone before?

Cheers
Mike

it's an on pop.. very common.. often caused by a bad earth.

one of these might help you:



I just fitted two of these, one for the RCA lead doing the front speakers and one for the RCA lead doing the back, I had a bit of noise through the speakers, fitted these suppressors and they've been great since

(But also try to find a better earth, in mine I drilled the body work and screwed the lead straight onto the bodywork)

Hm interesting, i get pops every now and then under specific circumstances. if you get this device mikejohno1 post here with your thoughts.

for £3.75 it's worth trying, like I said I know have no noise from my speakers at all, I've just ordered another one for the subwoofer, definately worth the money

I got one of these a while back from Maplins and it didn't change anyting. However, I relocated my earth and upto now, problem solved
Thanks for your advice guys

noise supressors filter top end noise, not bass tones, pops are caused by power issues, not by interference.. the device will not work for this, they are to combat floor noise or interference caused by cheap cabling.
