Aftermarket Radio

[Termanalor117]

i have a 1996 Tahoe Lt and i got a new aftermarket radio but when i took it apart i noticed there are like two harnesses that went into the stock radio. my new one only has a plugin for one, i assume the other plug is for the extra speakers. is there a aftermarket radio that supports all those speakers?

one covered power and speakers and such, the other is likely for the external add-on if installed. Like a cd or cassette player.
