[golf1.8t]

ok my subs seems to be pulseing when the stereo is turned on
things ive tryed

phono leads
remote wire
earth lead
all the pre-out in the stereo
different amplifier

its just out of my hands now maybe somebody could help?

this is in a 2001 mk4 golf

[Mr Blue]

think that happens to most systems. a ''pop'' noise when switched on / off

[jasonpi]

nothing to worry bout here, blues right most systems do that

tbh honest it shouldnt really but it is common... try running a wire from the h/unit earth to the earth on the amp, what side do u run power phonos etc down?? and what amps subs are u using?

Make sure you dont run power leads along side rca leads. I try and seperate everything! In my car now i run power down the left. High output speaker wire down the centre and rca's down the right. Then in the boot nothing touches or crosses each other.
