Four weeks ago I purchased a 2004 Mustang
Convertible 40th anniversary edition.
Installed is the Mach 460 sound system. The woofers were not working at the time of purchase, but I thought replacing the speakers was all I needed to do. I replaced the rear woofers with 4 ohm Kicker replacements to no avail. I'm reading that only 8 ohm speakers will work even though Crutchfield has an assortment of 4 ohm speakers that they claim will work. All connections are intact. The fuse for the woofers is fine. Can the amps be bad? How can I test the amps to ensure they are working? The front and rear tweeters are still working. Any thoughts? Thanks in advance for your help. Looking forward to some fun discussions.
