PAC SNI 35 line converter
Arc is 125.2 bx amp
Rockford fosgate 6.5 speakers

TESTING EQUIPMENT USED
SMD DD1
BLUE POINT 586 DMM


Using a 1k -10db at 3/4 volume was the happy spot on the head unit (not showing any distortion)
The line out converter was set with same test tone with 1.01 volts (11oclockish) before showing any distortion.
Amp was showing distortion at 20 volts with a clean input signal. I wound up setting the amp at 17.3 vac which was 75 watts rms per the manufacturer.

Note :When Using a stock Radio Sounds HU the Arc 125.2 amp is just about the biggest amp you will be able to fit on top of the HU without any modifications

Or you could try a line level converter and see if that helps. It will take the speaker outputs convert them to RCA outs and bump up the output voltage a bit.

I know a new head unit would solve everything but i use the bike communications and have an ipod interface I want to keep. Any suggestions?
