Beware of inadequate instructions
1989 Volvo 740
Crutchfield Customer Review (What's this?)
There would be 5 stars should the installation instructions make it clear that: a) both harnesses must be used for 1989 Volvo 740T b) speaker wires on the shorter harness are to be ignored. c) all speakers are to be connected to the longer harness. d) all of the panels under the steering wheel must be removed to locate the factory installed amplifier to disconnect its harness and mate it with the longer one (the amplifier may be discarded now)
Pros: Works well once you figure out the connections
Cons: Lack of clear instructions.
