Usually liquid damamge is not a repairable item as electricity is only meant to travel in certain ways through any device. I am sure the manufacture will service it for you, but as far as anything else probably just best to purchase new set.

Why Onkyo HTS-9400THX: Front both and subwoofer not working.?


Try differnt speakers, if they do not produce sound, amp channels may be blown and then you need to take it to a shop.

Fader/sub/speaker not working properly


I'm not an expert but often people connect subs to normal speaker wires in back of the radio. You need a dedicated subwoofer line so high frequency sound doesn't go to the subs. Only bass. Sounds like it wasn't wired properly.

Red light is on and subs won't play all the wires are connected correctly it all of a sudden just stopped working one day idk y


sounds like the amp is in protection mode. try disconnecting the subs and see it the light changes to green. if it does then the subs are your problem. if the light was allways red while it was working then the subs may be disconnected inside the box or have gone bad. try using a diffrent speaker and connect to the amp.

Is there a wiring diagram for the nikkai EAPA450 Amp


Hi, if you still need a photocopy of instructions email me mail@srands.co.uk

If you want instructions in brief this involves POWER CONNECTIONS, PHONO LEAD & SPEAKER CONNECTIONS:

POWER (At the same time when routing these wires, I would connect the PHONO LEADS from the car cd player to the amp, if your car cd player only has 1 preout (1red & 1 white) then you will need two phono splitters, a female to 2 males. Phono leads carry the unamplified sound from cd player to the amp):
~ Permanent 12V+ (Thick lead that is fused direct from battery all the way to the amp, wire must be 20a to 30a +, hence 1cm diameter wire, known as AWG8, Maplin sell cheaper kits then most)
~ Amp REMOTE (A thin insulated cable (5a is OK) from car cd player amp remote wire, this turns the amp on when the cd player is on, if your car doesn't have an amp remote wire, suggest nearest ignition supply or seperate switch that you turn on when you want to turn on the amp)
~ GrouND 12V- (Insulated lead (20a to 30a) to nearest part of unpainted car chassis such as interior panel screw hole, instead of an insulated cable all the way from the batery, this is common practise.

SPEAKER:
Each speaker has a - negative & + positive, these must connected correctly. The amp has 4 channel, 2 channel labeled as front, 2 channels labeled as rear. Using speaker wire, connect cable from amp to speakers. Note: Ensure the speakers being connected only receive sound from the amp (Not cd player as well, as would damage players or at the very least impair sound)
The amp has a feature called bridgeable this means a sub 8" or 10" sub can be powered by 'bridging' two channels. For example there are 2 ways to bridge power a Sub on the NIKKAI EAPA450:
i) Sub speaker wire positive + to channel RL and Sub speaker wire negative - to channel RR.
OR
ii) Sub speaker wire positive + to channel FL and Sub speaker wire negative - to channel FR.

Switches:
~ Bass boost, meant to be on for a channel if using sub, otherwise off.
~ X-over mode adjust hi/lo frequencies, only work if both x-over switches are on! Then adjust switch frequency knob, until it sounds right.
~ Gain (Volume knob) adjust volume knob up or down, until it sounds right!

NOTE:
You will need patience! many hand tools and parts such as: Wiring kit, fuse holder 20a/30a, Phono leads, speaker cable, Fork/ring connectors, wire strippers, wire cutters, set of screw drivers, also ueful to have zip ties to tdy excess cable and 'P' cable clips to tidy speaker wire to shelf, etc.

OK

Any more questions just email me mail@srands.co.uk

I have a Pioneer xv dv55 . My sub or speakers are not working!


I've had mine for nine (9) years and it fine, first make sure all coloured wire are connected to the sub correctly, press sys on your remote then press button 8 to test if the speakers are working then increase the volume to hear the spaekers. so to link TV audio/sound with DVD press sys then A-2 on the DVD remote, I hope these will solve ur problem?

Cd player plays, but no sound comes out of speakers.


first off the amp gets power straight from the battery. the amp is used to power the subs. the subs are suppose to be connected to the amp only( never the speakers).

for the second part you mostlikely killed the wires. you should get some one to look at it and check the wires. thee speakers might need to be re-wired

No sound


as u have speakers with u u connect another speaker in to the sub connection and reduce the volume to min and check if sound is coming use another wire to connect the speaker to the amp and if it is working u check the cable then the sub it would have burned off due to some internal problems and it has to be checked by a technician this problem may be due to wire broken or something like that

Crazy cycling noise


a quick test, change the speaker wires between the speakers, if the sound goes over to the other speaker the problem is in the amp. But if the problem stays with the same speaker tower the problem will be in one of the speakers in the tower. since you said you get no sub sound I suspect ithe problem is not the amp, but the sub speaker itself
