FAQs / Troubleshooting
Q1: The OPTI-1 works fine on AM/FM but as soon as I put a CD or DVD in the unit all sound goes away.
A1: Some aftermarket head units have an amplifier turn on wire as well as a power antenna wire. Normally, an
amplifier turn on wire is blue/white and a power antenna remote wire is blue. The power antenna remote wire
only outputs voltage when on Am or FM modes. The solution is to connect the blue wire from the OPTI-1 to a
wire that outputs 12 volts + in every mode from the aftermarket head unit (blue/white)
Q2: I installed the unit and I have lost all bass response in the vehicle. All the speakers are playing but I have no
low end.
A2: Some aftermarket head units have cross-overs built into them that limit either low frequency or high
frequency response. Refer to the owners’ guide of the aftermarket head unit and turn off any high or low pass
electronic crossover in the head unit to ensure a full range output.
Q3: I installed the unit and all I hear is bass but not high frequencies.
A3: Refer to answer 2. Also, make sure that you did not attach the RCA inputs of the OPTI-1 to the subwoofer
output from the aftermarket deck.
Q4: The OPTI-1 works and sounds great but I can only get balance left and right to function and not front to
back fade.
A4: The OPTI-1 does not support front to back fade due to the lack of any available aftermarket head unit with a
communication network. Balance will function but fade will not.
Q5: Will the OPTI-1 work with any aftermarket head unit?
A5: Yes, as long as the unit is capable of a full range RCA pre-amplified audio output and a remote amplifier turn
on.
Q6: I purchased an aftermarket steering wheel control interface and cannot get it to work.
A6: Steering wheel controls in every compatible vehicle are on the CAN network. CAN High is brown/red and
CAN low is brown in a twisted pair at the audio gateway. Please contact the manufacturer of the device for
support.
Q7: Will the OPTI-1 work with any vehicle that is not listed as being compatible?
A7: No, the OPTI-1 is only compatible with the listed model and year vehicles.
Q8: After reading the installation manual over and over I am still having problems. What should I do?
