I do have DSP, trying to find out if this will cause me issues. Thinking the line out converter may be the option after reading your BSW material. I have a MB Quart 4 channel amp, hopefully I can just attach stock wires (RCA) like you mentioned, I will look into this.

I'd love to upgrade with their system but I'm thinking I can get alot more sound for half their cost.

Plus I already half the equipment I'll be using.
