radio use a digital volt meter to see witch wire supplies voltage when radio is turned on and off, note placement on harness then verify this wire is hooked up on the output side aftermarket harness you may have to jump it to get more...
a lower impedance than recommended. Adding two speakers to one amp output loads that output with half the impedance of one speaker.
The themselves see. Also, when different speakers are wired in series, amplifier voltage will divide between the speakers unevenly, because different speakers have different more...
Hi Jrb10dl A quick way to tell is to measure the voltage on each speaker wire. If it is a High Power unit, of the unit alloows power to be turned on to the output stages. Check that you have ALL required power connections to the more...
