I have an Alpine MRP-M200 amp pushing 200W x 1 into my 2Ohm Boston Acoustics ProSeries 12.5LF subwoofer. Just this morning, after turning on the car, I noticed there was no bass. After making sure that the HU was set to NF ON, I went to the back and noticed that the light wasn't on (indicating the amp wasn't on). I tested the + and ground connections with a voltimeter, got a steady 12V with the car not on, and 13V with the car on. However, I got no voltage when testing the turn-on lead and the ground. Does this indicate that the turn-on lead is spliced or for whatever reason not sending the current?
What other ways could I narrow down the problem?
BTW- All fuses are good.
Thanks in advance.
