Arc Audio DSP-8 Installation On Toyota Harrier 2005

I remember when the Arc Audio DSP-8 came into Indonesia market around few years ago, I wonder that someday I could install this little DSP amplifier and see how it's perform personally. The selling point for this little DAC + 4 channel amplifier combo is the very flexible setting over the PC. With my busy life lately, luckily I still have a chance to installing it on the Toyota Harrier 2005. This DSP will replace the OEM JBL audio system.
