How to install Sub to 2006 Scion Tc factory radio?

Question

I have installed a Alpine radio and a Mtx Sub in my 2006 Scion Tc long time ago. Now I want to install back the factory radio. How do I connect the two red and black jacks from the Sub to the radio? I still want to have the sound system on. Help me!

Answer 1

you will need to install a "line output converter"

Connect the speaker leads from your car stereo to the it and it reduces the incoming speaker-level signals so that outgoing signals are compatible with the preamp inputs on your amplifier. You will then need to use two RCA patch cords to make the connections to your amp.

You need to find 2 sets of speaker wires in the car, behind the radio is the best place. Hook up the line output converter to the left and right outputs coming out of the radio, preferably using the rear speaker wires. You MUST make sure to get the phasing correct, ie positive and negative or you will have little or no sound. Then run the RCAs to the amp. Your car may have a factory amp, in this case you need to tap in after the factory amp

Answer 2

keep the after market radio...thats my opinion....but if not then go to best buy or a stereo shop and buy the plug...they will know what u need
