Line driver or Processor (bitone, alpine h800)
I have a car PC with Creative X-Fi soundcard. Two amplifiers in the car - 4-channel for 4 speakers and monoblock for subwoofers. I am planning on sending RCA's from sound card to amps. 360W PSU for PC. Will I require line drivers? If this is the case, would you recommend as an alternative to a line driver setup, purchasing an audio processor unit like the BitOne or Alpine PDX-H800 so I can control sound better? I am only using griffin powermate to manage volume on the PC, I don't think I'll have adequate control over my sound system?
What are your thoughts and solutions?
