1) Check speaker polarity carefully
2) Ensure that speakers are securely connected.
3) Check your Balance control
4) Check your inputs (change inputs L/R)
If that does not alter or fix the problem your right channel may have developed an internal fault. Repair or have it repaired.
If you know for a fact that the speakers work and have tried all speaker hookups then the pre amp in the head unit is fried. Only other thing to do, if you have aftermarket door speakers is to run an amp for them through front rca outs. If you have any other questions let me know.
You didn't indicate what car your radio is in, whether the car has factory amps that the pioneer is integrated into or bypassing, or if you're using the radio's factory amps to power the speakers, or if you have external aftermarket amps fed from the radio's preamp outputs. So with the lack of information, it's hard to say for sure what's going on, but I would suspect either you have a radio whose internal amplifier is dying, or your car has an internal amp that's being overdriven because your pioneer's internal amp is providing a powered signal to your car's factory amp which should never be done. There's too many directions in which to go to troubleshoot this issue because you haven't said anything about the make and model of your car or it's current sound system, so I hope I've given you enough of a foundation to point you in the right direction.
Yes....hook one up to the left channel and one up to the right.....once everything is wired up.....keep gain down on amp and turn stereo on.....turn up stereo with amp gain down to right before high end speakers start to distort......then while its playing, turn amp gain up about 1/2 way. close your trunk and hop in drivers seat....sound gd????? You might have to adjust level on amp and bass on head unit to taste.....Be careful though....pioneer subs are only rated around 300 watts continuous.....dont want to blow them...gd luck....
First; power conditioner won't do anything for your issue. It's not crosstalk (unless it's a wireless spkr) On your sub are cables mark + & - ? If so make sure they're attached accordingly to back of receiver/amp. Your distortion sounds like a phase issue. I'm also curious how store performed diagnostics?
The lpf-off-hpf switches control the "low pass" and "high pass" filters. When driving full-range or component speakers the filters are usually operated in the "off" position to send all frequencies to the speakers. When driving a subwoofer, the best position is "lpf". If you have a separate amp to power a subwoofer, this amp can be used just for the high frequencies by putting the switches in "hpf".
Input levels should be adjusted to match your receiver output. You don't want the levels so high that distortion results. But you want it high enough for the amp to be able to produce maximum output. Start at about midrange and adjust the receiver volume to a little higher than a comfortable listening level. Adjust the amp gain (level) counterclockwise until you begin to hear the speakers distort. The turn the control slightly clockwise until the distortion disappears. That's the best setting.
It could be a dirty control or switch, working them back and forth could prove that. Other than that, It's likely bad outputs. A unit that old may have transistors for outputs but might be IC's. Transistors can be tested with an ohm meter to see if they're good or not. Also if it has transistor outputs, they may have a small value resistor on the Emitters, check those as well.
