Amp playing speakers very quietly

this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....

remove all speaker connections to your amp. MAke sure the inputs are driving all 4 channels, and that the built in crossovers on the amp are all set to full range. Conect your full range speaker to each output channel one at a time and verify there is oputput on all 4 channels. If all is ok, then connect your rear speakers to the front(a) outputs of your 4 channel amp, and then use the second 2 channels (rear or B) bridged to drive the sub. Re-configure the crossovers for highpass for front (to drive your rear speakers) and lowpass for sub. This is the proper way to connect a 4 channel amp with a sup whle driving 2 full range speakers.

Short in amp ? try swiching wire's to speaker's around . if other speaker then work's , speaker's are both fine . if not , then short in amp , or blown channel in amp . get new one or find someone who know's more than i do about amp's

The amp should always light up showing you that it is powered and there will also be a red light that will light up if theres something wrong.Sounds like maybe the hot wire that goes to the amp isnt big enough to give the amp enough power.Check your positive wire and ground wire for tightness and make sure hot wire supply is big enough and also the ground wire is big enough and has a good ground.I hope this Helps you.Have A great day..

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

Instead of connecting it to the sub output, try it on the L or R output of your amp.
This will eliminate the Denon.
If this fails, you need to test the loudspeaker driver unit whilst disconnected from the sub amp. Use a 1.5v cell (AA or bigger) connect using croc leads to the speaker's terminals. If the speaker is OK, you should hear a click. If you hear nothing, the speaker unit is faulty.

YES!! You used the blue wire to turn on factory amp (blue wire to GM pink) you NEED to use the Blue/White wire. That is the amp turn on. The blue wire goes dead when you play a CD or DVD because it's for a power antenna. So, Blue/White ok?

This is common with the type of powered speakers where the IC package that drives the speakers (the amp) is getting to hot and shuts down. Usually it is damaged and not reversable. There is a lot of reports of this same model loosing one channel or playing quietly. The air most likely cooled the chip down until it heats back up.

Some older Pioneer radios require you to connect the Subwoofer RCA to the rear output on the back of the radio and then you have to turn on the subwoofer in the menu on the radio. What model Pioneer radio is it? Also, make sure that the RCA plugged into the amp is on the input side, not the output side.

your amp may be overheating, or you have it up too loud and the surge protector is shutting it of in fear of damage to your amp.
