pop pop sound from subs..

**n/a** · 18-04-2007 07:32 PM

hey guys, i DIY'd a full sound system (HU,subs,amp,speakers) and everything worked fine, BUT, i recently changed the HU to a crappier one and now when i change from tuner to cdplayer (vice versa) it makes a loud *pop pop! from the subs irrespective of the volume setting..

i think maybe the RCAs make be in the wrong slots, but i want to be sure thats the problem (its a bloody hassle to get to the HU) or could it be the HU itself?!?

hey dude does it sound like theres a screw loose and its "jumping" off the sub each time the bass hits?
if thats what it sounds like id say your sub is gone, im in the process of getting a new sub put in because it dropped a voice coil and it was making a pop pop noise

it doesnt make that sound with a diff HU, so i think the subs are ok.

i'll play around with the RCAs and see how it goes..

Hey mate,

its your amp. Cheaper amps have that, if you try swapping it one day to a high end brand it wont make that sound, unfortunately you cant do anything about it. I lived with my jaycar one for 1 yr before i ripped it out - no more pops!

don't be rude paul! it's a rockford amp! punch punch!

it was the rca.. not fixed, but it's quieter now.

it's either the amp or deck... but since its a rockford, they have proper powering delays to prevent the pop therefore its your "new crappy deck". i'm guessing your amp is remotely turned on via wiring to the decks antenna wire? their not surge protected on cheap decks as they really are meant for just the power antennas

hi guys... got the similar problem here... but it pop pop when i was on the road after quite a long time and a bumpy road as well... it gets better now since i swap the HU to a much better one... but it still happens sometimes...

any other suggestion?
