Hello everyone, was wondering is 1992 civics need a line output converter for an amp and sub?

 

Of course... you would need a pair of RCA plugs (red and white) on the back of the radio to plug directly into an aftermarket amp. The line converter turns speaker leads into RCA plugs.

 

line out converters are used when amplifiers are being installed with factory head unit.
do you have a factory head unit?

 

I know this is a dumb question but is the head unit what the stereo connects into? Or is it the stereo system that has an eject button? The stereo that can pop in and out is aftermarket but I believe the rest is stock. Although there is a AUX cord that isnt connected to the front of the stereo so maybe not?

 

For heaven's sake... your lack of pertinent information given challenges us in helping you appropriately... please post a picture of the back of your aftermarket radio.

 

I took a look at it more with a friend and it is aftermarket.

 

your aftermarket radio should have rca
no need for line out converters.
