My sub has a slight pop each time the system is turned on. The way it’s wired is Helix DSP.3S hardwired remote from accessories and then all 3 amps remote bridged off the Helix. The other 2x 4ch’s/front stage are fine, it’s just the sub/mono that pops. Amp is an Alpine PDX-M12 and sub is an Image Dynamics IDQ12.

Any ideas on what might be causing this?

Thanks!

if you remove the sub amp rcas and the pop goes away, try increasing the dsp turn-on delay.

if the pop still exists with the rcas removed, look at adjusting the amp settings like gain, bass boost, etc. check install-related stuff like grounds.

if the rcas are unplugged, all the settings have been completely fiddled with, install related issues resolved: then it might be a bad amp.

Would delaying the DSP work seeing as my amps are hardwire remote bridged off DSP?

How much delay are we talking?
