Having trouble with all my speakers except my twitters in a 2007 Saturn Outlook...what do I start with? Fuses are good


Speakers get power from the amp if your system has one or from the radio , if the tweeters work it's not a fuse problem . You like listen to your stereo loud . Blew a channel in the radio or amp ?
Take it and have it checked for DTC'S - diagnostic trouble codes
DTC B1025 01: Audio Output 1 Left Front Circuit Short to Battery
DTC B1025 02: Audio Output 1 Left Front Circuit Short to Ground
DTC B1035 01: Audio Output 2 Right Front Circuit Short to Battery
DTC B1035 02: Audio Output 2 Right Front Circuit Short to Ground
DTC B1045 01: Audio Output 3 Left Rear Circuit Short to Battery
DTC B1045 02: Audio Output 3 Left Rear Circuit Short to Ground
DTC B1055 01: Audio Output 4 Right Rear Circuit Short to Battery
DTC B1055 02: Audio Output 4 Right Rear Circuit Short to Ground

Each of the audio output channel circuits (+) and (-), at the radio and audio amplifier (if equipped) have a DC bias voltage that is one half of the battery voltage. When using a DMM, each of the audio output channel circuits will measure approximately 6.5 V DC. The audio being played on the system is produced by a varying AC voltage that is centered around the DC bias voltage on the same circuit. The AC voltage is what causes the speaker cone to move and produce sound. This voltage will vary depending on what type of audio is being listened to, talk or music, and type of music, as well as the volume setting of the system. Low volume and talk settings will measure around 1V AC and less, where constant music may measure 3 V AC and slightly higher.
Do you know how to do DC voltage testing ?
Without Amplifier without UK6
Ignition OFF, disconnect the harness connector at the appropriate speaker.
Radio ON, test for 5.0-7.5 V between the signal circuit terminal A and ground.
? If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
? If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
Test for 5.0-7.5 V between the signal circuit terminal B and ground.
? If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
? If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
If all circuits test normal, replace the speaker.

Sherwood RVD 6095rds Hi. After a short while of about 20 minutes. My speakers cuttout like they are losing connection. Next I hear some loud pops from the speakers. And it resets itself to standby.


Sounds like DC leakage....pre-drive and/or output transistors (or IC) becoming intermittent often pass DC voltages to the speakers. The "pops" you hear are these DC pulses being passed to the speakers and the "cutout" is the protection circuitry doing its job...protecting the speakers. Speakers want AC voltages...plus voltages moving the cone in one direction, and a negative voltage moving it in the opposite direction. DC voltages push the speaker cones in a single direction and hold it there until it fails. The bad news...it's repair shop time.

What voltage and polarity do the ACS-5 speakers require?


Computers always use DC voltage. Computer speakers receive DC voltage from the computer.
DC voltage has a Positive and Negative polarity.

In the power jack of the speaker, the Center pin is the Positive connection. The outer shell is the Negative connection.

Center hole of the DC adapter plug - Positive.
Outer shell of the DC adapter plug - Negative

Voltage 5 Volts DC.

Makes an loud clicking/popping sound


The audio outputs are intermittently shorting to their supply and allowing DC voltage to pass - the speakers will be damaged if it continues. you can confirm this by measuring (with a dc voltmeter)at the speaker outputs for DC volts.

My desktop speakers don't work.


What do you mean, "cleaned out my computer"? If you mean removing software then you've probably removed drivers for the audio hardware in your computer. If you got a "driver" disk with your computer, re-install the sound drivers and you'll be up n running in no time !!!

Looking to see if there are rca hook ups on subwoofer


There are not RCA Hookups on any Raw Subwoofer. An amplifier takes an RCA input signal (DC) and turns it into AC to the speaker.
This is a raw driver. It has wire push terminals just like any other driver (speaker).
See here....

Output voltage of 120volt AC brick & approx dimensions


Any PC speakers that have a AC plug pak attached can probably use 12V simply cut off the AC plug packs lead that goes to the speakers, and connect up 12V ya should be good to go.. some connect with a Phono Plug, and usually the Outer is Minus Voltage and the Centre is Plus Voltage .. they are also generally Diode protected so a reversal shouldn't cause too many probs...

No Power


Hello jasper100, Have you opened the unit to take a look inside? Since you dont have a blown fuse we cans assue the a short has not occured. Now I would chect to see if the voltage regulator in the amp has voltage coming from it. It may not in that case you may have to remover the old regulator and put in a new one just to get to the point of properly troubleshooting this amp. I would suggest that you get a schematic for this unit and use a multimeter to look at the voltages in the power supply section and see which sections have no rail voltage (12v supply voltage). I would also advise checking the remote to for regulator failure.
