Determining the Cause of the Problem Let's assume our system has a head unit, a crossover, a two channel amplifier and two door speakers with only the right speaker working (the left speaker is not working). If the door speakers are behind the door panels then we want to make sure the speaker is the problem before removing the panel.

We'll work backwards starting with the amplifier and ending at the head unit. Testing for a Speaker Problem With the vehicle and the stereo turned off disconnect the speaker wires for both the left and right speakers at the amplifier. Now connect the left speaker to the right amplifier output (which we know works). Turn on the stereo system and make sure the balance is set to the middle position.If the speaker still doesn't work then the problem is somewhere between the amplifier and the speaker Testing for an Amplifier Problem Now we'll need to see if the amplifier channel is bad. Put the left speaker back on the left amplifier channel and the right speaker on the right amplifier channel.

This returns the speaker wiring to its original configuration. Again, with the vehicle and stereo off unplug the RCA cables from the amplifier's input and switch them so the left cable is in the right input and vice versa. Turn on the stereo system. Testing for an RCA Cable Problem For any intermediate components between the amplifier and the head unit follow these steps for each one.

We only have a crossover so we'll just do this once. Begin by testing the RCA cables between the intermediate component and the amplifier. Unplug both RCA cables from the intermediate component's output. Now plug the working channel's RCA cable into the non-working side of the crossover. In our case the working channel is the right so plug the right RCA cable from the amplifier into the left side of the crossover. Turn on the stereo system.

If the right channel continues to work then you know the problem is in the RCA cables between the amp and the crossover. Esting for a Crossover or Equalizer Problem At the input of the intermediate component (in our case the crossover) flip the RCA cables around (left to right input and vice versa).

Turn on the stereo system. If the right channel continues to work and the left channel continues to not work then you know the problem is in the intermediate component. Replace or repair this component. If the problem is now in the right speaker and the left speaker works then the problem lies before the crossover. Turn off the stereo system and return the RCA cables to their normal places.

Testing for a Head Unit or RCA Cable Problem Pull out the head unit from the dash so you can access the RCA cables. Unplug both RCA cables from the head unit. Do not disconnect any other wiring. Plug the right RCA cable into the left channel of the head unit. Turn on the stereo system.

Sep 29, 2016 . You would have to install a speaker selection switch. You cannot directly hook up 2 amplifiers to one set of speakers without destroying one or both amplifiers. Unfortunately, one set of amplifiers is inside your sound bar. An external switch would have to be installed on your sound bar as well as speaker terminals that would connect to your Fisher. If you have a line out or tape out on your Fisher, and you have an analog input on your sound bar, use could use that as an alternate solution.

Dec 01, 2013 . Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier. How to Connect a Subwoofer to the Subwoofer Output The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver.

Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated.1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer. How to Connect a Subwoofer to Speaker Level Outputs Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer.

Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers. Hope it helped. Apr 20, 2011 . The amps are located inside the radio. Most in-dash receivers that provide for 'pre-amp outputs' also called 'low level outputs' do so by providing female RCA type jacks.

These are often found at the end of a short (4 - 6 inch) cable and are usually color coded red & white or red & black (some receivers provide a yellow RCA jack for video in / out, too). To use these RCA audio jacks, you need to realize that one jack is for the left channel source and the other is for the right channel source for a stereo signal. You will have to connect a compatible plug and cable of enough length to extend to a remote amplifier's RCA input jacks. The vehicle's speakers would also need to be connected directly to the same amplifier's output terminals. Using the two audio (left and right) RCA jacks will only allow the radio to control balance of the left and right audio, no fader (front and rear) control is possible.

To get fader control, you'd have to either have a radio with four RCA low level output jacks (front L & R *and* rear L & R), or use the radio's speaker (or high level output) wires and connect them to the amplifier's speaker (or high level) input terminals. Chickering Grand Piano Serial Numbers on this page. All unused receiver wires should be terminated in a wirenut or securely wrapped in electrical tape to prevent accidental contact with grounded metal or other wires behind the dash.

I hope this helps! Nov 11, 2009 . The solution is simple and cheaper than you think. The analog 5.1, 6.1, 7.1 outputs on your receiver should be active even with digital inputs that you want to hear.

Your receiver turns everything it processes into analog output just before the speakers anyway so there's no loss of access to multichannel sound this way. What I did was to buy a separate amp for the 901's and feed the Front L&R analog audio out to the EQ which is directly in front of the amp. The Active EQ is only for the 901's which don't have woofers or tweeters so Bose flattened out its final response electronically with some serious boosting at both ends. Having it in line with any other speakers would feed them a grossly over-compensated signal. Your receiver will drive the rest of the speakers. This is the cheapest way to have your 901's and hear them, too. Since the 901's are really efficient you don't have to buy a big amp that would heat the room.

I'm using a separate Carver amp with 2x100w for mine. Sep 09, 2008 . If you have a 4 channel amp and 4 speakers and each speaker is connected to each of the 4 channels you are just fine. A stereo amplifier has 2 channels, typically labeled left and right and each channel has an amplifier. A 4 channel amplifier has 4 amplifiers. With one speaker on each channel, there is one speaker on each amplifier. Audio amps are referred to as amps or amplifiers, although if they have more than one channel it would be more correct to call them something like 'multi-channel amplifier' or 'multi amplifier speaker driver'.

• 8546 Answers SOURCE: I can't even find a reliable picture of the amp but it's not rocket science. The Tuner output goes to, say, FM or Aux on the am, anything BUT Phono, which is ONLY for a turntable. The EQ output goes to the first available Tape In; Input Comes from the same Tape Out. Select that tape function to engage it in line with any source and the downstream electronics (second tape, tone, volume, speakers).

The tape deck output goes to Tape In; Input comes from Tape Out. If there is not a second tape loop on the amp, nest the Tape Deck into the EQ's Tape loop. They always have at least one to replace the one they use. Select THAT tape function to engage it in line with any source and the downstream electronics.

Register and download the manual for free audio.manualsonline.com Keeping in mind this is just an analog Dolby Pro Logic receiver, there are limitations to what it can do sonically. Dolby Pro Logic is NOT 5.1 as I'm sure your DVD and possibly Cable Box are capable of producing. KM-106 is just a power amp. No mysteries there. Feed it something, attach speakers, duh.

If you want to slave it or drive a separate passive subwoofer with the Fisher as the central control, the best you can do is borrow analog stereo Line Level out from the unused Tape 2 or Video Out, but don't actually select them on the front panel. THAT would disconnect whatever source you were listening to. And you WONT have local control of the volume as you would with a real AV Receiver. Sony DVD player (what model?).

I'd just run audio from it to the Fisher and Video to your TV, unless you want ONLY composite video quality. ADC-SS2: See Figure 5 in the Fisher manual. Hook it where they show the cassette deck, using Line In and Line Out of the SS2.

If you want to use a Tape Deck or 2 attach them to the SS-2 in its Tape loops. Apr 19, 2011 . Your connections seem to be right. Let's distill this down to its simplest configuration. Does the onboard FM produce sound?

If not, nothing will. NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING. Turn the volume control to something medium. The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected. There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control. Turn the volume to something reasonable and see if that helped. Apr 17, 2011 .
