Had issue with my speaker was cracking on low tones, so I replaced it with aftermarket ones 260w once I done it put all trims back, new one is still cracking on low tones so dont know wat is goin on?

New one broken as well?

or is it possible some dodgy speaker wire or connection make crackin cone noise?

...are you runing a amp???....... probably not......

no amp mate,

I used to do it on Skoda OEM cd player and speakers then changed for Sony HU did as well, then changed speaker still does it!

dont know why
