Dear All
I am having some challenges with my audio setup, which consists of : JBL MS8 Alpine PDX4.100 L7 Speaker setup incl centre Earthquakes for the under seats The processor drives all the speakers in the car, the amp drives the subs. I am getting no sub bass whatsoever now. Checked the amp and the lights are on and both fuses seem fine. Any ideas people?? Would an amp fail whilst still having the lights on. ? How can I check it ? Any direction welcomed - cheers

Should also add I've got 4 gauge from the battery separately fused, which feeds a distribution block which is fused again and this feeds both the amp and processor via 8 gauge. The processor is working and as said the amp lights are on ?

What colour is the amp light on? Red or blue? If red then wiring problem, please check wiring input and crossovers all as it should be or not.

Can you bench test the amp then? Is your HU coded to hifi, if not can you try connecting output directly to the sws-8 and see if they play.
