Re: my amp works but my sub doesn't...!!!????????????

Whats the condition of your amplifier? New , Used, Old?


You might have a blown channel off your amplifier, this may cause little or no sound. You will have some distortion, crackle sound and then maybe nothing at all. What kind of subs are you running to it? Make sure the subs arent blown and check the voice coils to see that they are not torn off the subs , these are the 2 little silver or copper wires that are connected from the speaker connectors to the sub itself.


Let me know what happens?

The light is red and no bass is coming out of my subs

The Amp Is Most Likely In Protection Mode... 2 Ways To Figure Out Whats Wrong With it Is Check Every Single Wire And Make Sure That Every thing Is Hooked Up Correct And There Are No Bad Connections With Ur Remote Wire, Ground Wire, And Battery 12v Wire, Rca Cables As Well. If Every Thing Checks Out Good Then Try Checking The Fuses And Make Sure u Are Using The Correct Fuses That Are Good For That Amp. If U try These 2 Things And You No Your Subs Are Hooked Up Correctly Then The Worst Is Probably There. I Had The Pioneer 7200 Amp And It was A Blown Amp And The Red Light was Constantly On. No Sound No Nothing. If U Try Those Steps And it Still Does Not Work Then Most likely Your Amplifier Is Toast. Hope This Helps :-)

I have this hooked up and works fine with the key on, but when i start the car, sub light, amp and sub dont come on.

You have connected it to the wrong power wire - one that is only active in service mode - first key position.
You should draw a wire directly from the battery (don't forget to add a 40 amps fuse on the wire) to the amps. If you don't want them constantly operational (you will have to manually shut them down) install a relay on the wire with the command coming from a wire from the instrument key position - second position of the key. Use a voltmeter to identify the wires.

My jl 500.1 amp dosent play anything.

you have your sub wired incorrectly. your amp shouldn't get hot unless you're settings are too high or your'e sending too small of an ohm load to the amp. this would cause it to heat up and will fry your amp.

Amp burned out but fuses still good?

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....

I bought a 500/1 jl audio amp and also a w7 10 sub

if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

Ok this problem is killing me...

maybe the speaker is bad

First try one thing, switch the rca jacks around and see if the other speaker stops working this time.

If so the problem is in the rca jack or head unit.

If the same speaker is still not working, the problem will be the speaker, you will have no other options left since you changed amplifiers and checked all wiring.

Let me know if this helps you

Subwoofer Wont Work

If the connections are correct...?
then it doesn't sound like theres a problem with the amp.

make sure the amp is not to powerful for the sub?
eg: 1000w amp, 500w sub.

Sounds stupid but it happens.

make sure the gain / volume is not too high!

if your BMW has a totally sealed, metal boot area this doesn't help.

Amp not powering up??

the sub amp may be damage, shorted. you may have a wrong speaker hook-up the first time you use it. too low impedance may have damage the sub.

Pioneer amp and sub problems

That's a 4-channel amp, not a 2-channel, which makes me wonder exactly how you have it hooked up to your sub. Is the LED light on the amp coming on? How many subs do you have hooked up to it, and how is it wired?
