Just bought a JL Audio CL-RLC line driver. Going to use it to turn down the volume of the in cabin speakers when I crank up the tower speakers. I知 also using it to boost the input signal to the JL M6600 6 channel amp from 4V to 7.5V. Currently, I have one pair of 4V pre-amp signals feeding the six channel amp so that 4V is being split 3 ways. The increased signal voltage should give me a little bit cleaner sound although truthfully, it sounds great now. Really got it for the volume control function. Thought about getting the Kicker unit but the JL has much better specs (lower THD, higher S/N ratio).

I値l report back as to how well it works once I get it installed and tested.
