Hello I am new to the forum and fairly new to car audio, so hopefully someone can help me out.
I am re - working the system on my 69 Cadillac Eldorado.
System has a Panasonic CQ-C5401U head unit.
Not sure what the front speakers are because there boxed in and I have not opened up yet, but there working.
10" punch sub in the trunk
I just put in a new Alpine MRP F300 amp.
Seems as if one of the rear Memphis 6 x 9's is blown.

What 6x9's would make a good replacement?
