Re-installing Factory Radio 92 Silverado
 

I am removing an aftermarket radio in a 1992 K1500 Silverado. Currently the head unit is in the aftermarket housing where cassette player resided.

I purchased a complete set (OEM Radio head unit, in dash AMP and Graphic Equalizer / Cassette player.

I also purchased the correct Bezel for the cassette unit.

They all have appropriate cables and hook up properly to Amp.

What else will i need to complete the install ?

Do speakers get plugged into amp ?

Any help is appreciated !
