Will a pioneer receiver vsx d309 run 2 8 ohm speakers and 1 jl audio w3

It will drive the speakers but not the subwoofer. U need to connect the subwoofer pre- output from your amplifier to another amplifier that will drive the subwoofer.
If you connect the subwoofer directly to your amplifiers speaker output it will force the subwoofer to play the entire spectrum of frequencies (not designed to do that) consequently causing damage to the sub and maybe even the amp. So use the sub pre out.

hope this helped

Hello, I have an old Pioneer VSA-1000 home theatre

I have a Pioneer VSA-1000 with what sounds like the exact same problem. It is the world wide model with multi-voltage selectors.

I bought a schematic a couple years ago that I found at www.servicemanuals.net. Cost USD $21 at the time.

No power to my amplifier

REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL DOES NOT POWER UP, THEN CHECK THE VOLTAGES AT THE POWER TERMINAL TO GROUND AND MAKE SURE THAT THERE IS 12 VOLTS PRESENT. ALSO, CHECK THE REMOTE LEAD VOLTAGE AND MAKE SURE IT IS NOT BELOW 11 VOLTS, WHICH COULD BE CAUSED BY A DAMAGED REMOTE OUTPUT FROM THE RADIO ITSELF. IF YOU ARE UNABLE TO CHECK THE REMOTE LEAD, THEN DISCONNECT IT FROM THE AMPLIFIER AND TEMPORARILY INSTALL A JUMPER FROM THE POSITIVE POWER TERMINAL AND THE REMOTE INPUT TERMINAL ON THE AMPLIFIER, WHICH SHOULD FORCE THE AMPLIFIER TO TURN ON. ALWAYS MAKE SURE TO VERIFY THAT THE POSITIVE AND ESPECIALLY THE GROUND CONNECTIONS, ALONG WITH THE REMOTE CONNECTIONS ARE 100%. IF THE AMPLIFIER STILL FAILS TO TURN ON, THEN THE IT WILL NEED TO BE SERVICED. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

Pioneer 6300 F

firstly, you might want to check if the resistance of your speakers (out-of-circuit) are in specs using an ohmmeter. If it's rated 4-ohms then it should be reading near 4-ohms resistance otherwise it is damaged.
secondly, if the amps can be powered 'on' make sure that it has no dc voltage in the outputs. If there is a signal source an AC voltage will dance the meter pointer which indicates that your amp is OK. Only then can you reconnect your speakers (not the damaged speakers duh!).
cheers!

Source input problem

Hi Seamus377

You have a faulty input selector chip by the sound of it. First, power the amp off at the wall for 30 mins, then fire it up again to see if that resets the problem.

Hopefully that fixed the problem, if not, you may need to get a tech to look at it. The input selector chips are quite sensitive and susceptible to failure, producing the symptoms you speak of. They can be damaged also and fail at any point if subjected to a voltage spike. Here is why they fail

When outboard devices such as
  1. TV that has an outside aerial
  2. VCR with Switch Mode Power Supply
are plugged into your amp, the RCA connectors connect the center "signal" connection first, then the earth ring. Until the earth ring connects, any potential difference or stray voltage present on the earth of the connection being plugged in, can result in as much as 50volts being spiked into the input selector chip. I have seen scores of amps damaged by this.

How to avoid it

Before making any connections to your amp, FIRST
  1. Disconnect external aerials
  2. Turn off all equipment at the wall socket
  3. connect all the gear and aerial LAST
  4. fire the gear up
Good luck, hope you get it sorted out.

Bose amplifier does not work with a 6 speaker selector

your wall speakers may not be connected.... disconnect each speaker from the selector box and test with a small AAA battery to see if they are connected by putting the battery between each speaker's wires , you will hear it crackle ,then gradually connect each wall speaker onto the speaker connector box . If the first set does not work i suggest there may be a problem with your speaker selector box . Good luck
