It is not hard to check if it is a blown fuse. Is it only the amp that isnt working?

i want to say you probably blew your fuse on your amp and if your not lucky you might of done some damage to your headunit. i would first meter and see if your remote wire is reading 12v with it on and work towards the amp.

Matt86, check the phase of your subs. if one of them are switch than it'll sound pretty bad like that also meter your subs and turn your dvm to check resistance, it should be around 4 give or take an hundredth of an ohm. also could you give a better discription of what going wrong. does the amp turn on, did any of the fuse blow, if so which fuses blew? when did it happen?

i don't think the subs are being underpowered since the subs are 200w rms. i'm not sure what the ratings are for the amp is but should be enough to power the subs. depending on how you wired the subs your running subs 2ohms or 8ohms each in stereo or 1ohm or 4ohm in parallel. i would say running that amp at 2ohms or 1ohms would definately mess up your amp. i'm not sure how well the kenwood amps handles the 2 ohm and 1 ohm load.

have you tried the subs on a diff car? have you tried the amp with a diff sub?
process of elimination.

At any point did you notice a weird smell when your problem started? If so you blew a sub or a speaker...it stinks like ruber or plastic.

i Havent ever heard of a sub being blown because of it being underpower if anything it is good that the subs have more wattage capibilities then your amp so that way you dont have to worry about blowing one out, also that farting noise is from a mismounting of the sub if you installed ity your self maybe you didnt mount it correctly it could be that you drilled one of the screws in sideways and that lets air excape which is not bad but it doesnt sound good when you open your trunk to hear them. But yeah as for your blown question you want to check the fuse first change them and check the REM its easy to connect but yeah after that then unplug both subs and check each one seprate with only 1 plugged in at a time ( you must take your key out of the ing. everytime you check ewach sub to restart your amp)with your amp on if your amp kicks on with one of the subs then you indeed have a blown subs. Most amps shut off when it detects that theres a problem to prevent further complications , also quick check you want to smell your subs (sounds weird but it works) to see if you smell burnt rubber /plastic or you can push your subs in and out to feel a crunchy stiff feeling to check if your coils in your subs just crapped out. Also wouldnt hurt to take the subs to a friends house for use with there amp.Hopefully this makes sense get back to me if you solve your problem. car audio can be fustrating :crazyr:

SUBWOOFERS DO NOT BLOW BECAUSE THERE IS TOO LITTLE POWER


They do NOT. What most people are probably refering to is the fact that their amp provides too little power and they turn the gain knob up way too high to compensate for the fact that there is not enough power. Turning up the gain will lead to clipped signals, which can lead to broken woofers.

In fact...

Take this scenerio. You have a 1000 watt amp powering a 1000 watt woofer. The woofer is NOT getting 1000 watts of power for every single note that it plays. When your volume is close to ZERO, the amp is NOT feeding the woofer 1000 watts. So if sending too little wattage blows a sub, our subs will all blow when we turn the volume down.
