M340 HK System no Bass. Way to check amp?

kohlzor · 10-15-2023, 05:09 PM

Hey All,

My M340 with the HK system has no bass at all for a few weeks now and previously it would come back on its own after restarting iDrive or turning car off and on. I tried replacing the AMP buy getting a more recent one but same issue no Bass at all.

Is there a way to check if the AMP is getting power or a fuse I should be checking?
Next step would be to try replacing the sub woofers but just seems odd that both the undereat subs would go out at the same time.
