To find a bad connection in a speaker wire, start by visually inspecting the wire for any visible damage, fraying, or corrosion at the connectors. Next, use a multimeter to check for continuity by placing the probes on each end of the wire; a lack of continuity indicates a break. Additionally, you can swap out the wire with a known good one to see if the issue persists, which will help confirm if the wire is the problem. If the issue continues, the problem may lie with the speaker or amplifier instead.
Turn the power off, disconnect the speaker wire from both front speakers, connect the right speaker wire to the left speaker, at this time the original left speaker wire should be laying in the floor not connected to anything, be sure not let the paired speaker wires TOUCH each other. Turn the power back on and turn up the volume to normal level. If you hear sound from the Left speaker, one would tend to think the Right speaker might be bad. If you Don't hear any sound, the amplifier or speaker wire might be bad or a poor connection. IF there is a Balance control, be sure it is in the middle and not turned all the way to the left, which would cause the front right speaker not to have any sound.
Static coming from some but not all speakers is usually caused by a loose connection at that speaker or a loose speaker itself. It can also be cause by a wire with insulation worn off, and touching a body part.Static coming from some but not all speakers is usually caused by a loose connection at that speaker or a loose speaker itself.

A bad ground wire or ground connection.
most likely it will be low if you use wirless connection but if you are using wire then your connection is bad.
Loose wire or bad connection to light.
Loose wire or bad speaker.
it could also be a bad preamp or whatever there called inside the place were the speaker goes... run test leads(2) directly from the rear of the radio (at the right speaker lead)to the speaker itself. If the speaker now works you have a broken wire in the harness. It is easier to run new speaker leads than try to locate the break. This seems to be a problem with Cherokees.
That is typically casued by a bad seat safety switch, a bad connection at the switch or a bad wire going to the switch.
most likely the switch is bad, or the wire plug has a bad connection
The wire runs under the Jeep and has probably rusted out or has a bad connection.
A person can find a neutral connection point is testing the continuity of every neutral connection. This technique will enable a person to find a bad connection point.
bad spark plugs or bad wire connection to the spark plug
