i assume you have the monsoon system?
then yes. I'd doubt check a wire schematic first though. (we have a link somewhere on site for them)
also... for the LOVE OF GOD, don't run your power wire through the door... use the grommet like an adult.
and if audio quality is of a concern for you, I'd agree with the others. After all these years of being on here, the line level converters are a temp thing... while you save money for the proper setup. I hope they last a little bit for ya.. but usually, its the stepping stone.
btw, ryan is exceedingly harsh sometimes, but its only because experience makes him grumpy. (that and old age.
