Just received my channel swap cable

Cut my hands to shit but it was so worth it - simple job of pulling the panel out and prizing out the chunky white connectors and then plugging in between and putting it all back in...
Fired it up and the difference is immense, I'm not talking sound-off quality but considerably louder than the piss poor standard setup

very satisfied !!! And would definitely recommend it for a reasonable improvement instead of installing amps and more speakers !!!
