I have no warning sound and no sound from speakers even after changing the Hk amp with another same Hk amp, any clue what it could be?

Does the volume control knob on the head unit still work?

Hello. Yes it does, it may not be too obvious from the video but everything works exactly the same, just better with a new amp. Ideally to use MATCH UP 8DSP / MATCH UP 10DSP.
