Are the frequency switches on the amp both on full pass or High pass?

Edit
If the voltage is different from the LOC to amp you will have a different tone coming out of the amp to the speakers possibly causing the difference in sound even if the output voltage of the amp is set the same the input voltage to the amp via the LOC being off a little will cause a sound difference

POSITIVE lead on the center rca pole and negative on the outer ring
I am trying to remember what the output voltage on the output of the LOC I used on the last set up that was similar to yours.I want to say it was around 2.5 VAC
I have the numbers in my notes at home and I am stuck at work till 10pm.

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
