If you are metering outside the vehicle then I get it. The other option is the M1 has tons of slack on the cable. You can always stick it to the bass knob and bring it outside like a regular bass knob.I've seen plenty of those but having a bass knob with a clip light is very important to me. I'm sure @Popwarhomie knows what to do without going the rca route. Is it weird that I give demo's just like I meter and compete? Ut's funny when people ask me if I'm the guy with the 8's that they keep hearing about. I'm just a construction worker who listens to talk radio all day. That shit cracks me up.
