INPHASE AUDIOBAHN Sub Woofer Not working

is your subwoofer self amplified? if it has, you can connect it through audio sub output and in put to your self amplified subwoofer.. if it is not self amplified, you can still connect it but be sure it ca drive your subwoofer, it depends on RMS or watts of the original sub of the srround..or you can have a seperate amplifier only for your subwoofer. "Audio out - Audio in"

your sub woofer has only one input to make it work. plug in your rca cables into the back of the sub woofer and the other end into the audio out or subwoofer out put on the back of your surround system.
also has 2 speaker inputs so you can expand your speaker setup. plug thos in and you can hook up 2 speakers to th output on the back of the sub.

In theory your idea would work, however you risk damaging your amp by reversing polarity and the positive and negative wires from your head unit are low voltage so they wont provide enough current in reverse or normal polarity to free the cone of your sub. but here is something that you can try that is similar in concept.

Take a positive lead from your head unit and wire it to the negative of your sub. Now ground the positive terminal of your sub to the vehicles chassy using a wire. This creates a 12v-14v reversed polarity current that should be strong enough to (POP) the cone so to speak. hope this helps

simply give it a 2 wire signal and you should hear something! if not then depress the cone lightly back and forth, if you hear alot of scratching/scraping sounds, prognosis in not good.

test with a digital multimeter set to ohms. if you don't have one of those laying around grab a 9 volt battery and run wires from the 2 terminals on the battery to 2 of the terminals on the woofer. if the woofer pops out you are said to be "in phase" (even though it has more to do with polarity that phasing but regardless) which means the positive from the battery is on the positive of the woofer and the negative is to the negative. those 2 terminals on the woofer are a single coil and obviously the other 2 terminals are the 2nd coil. now depending on what impedance each coil is will determine how you have to wire it to be 4 ohms unless they are 4 ohm coils which means you just use one coil and it will be 4 ohms on that woofer.

cone is cracked if you see the crack sometimes epoxy or rubber glue can wrok but Id ship it back to audiobahn if under warranty otherwise buy another one as shipping and repair gets expensive

i dont ever get tired of saying it LOL A2300HCX audiobahn

I used to have exactly the same subwoofer. It has dual voice coils which are driven independently.
Hope the diagrams help out. Just make sure you know how many ohms your amp is.

alot of times its not just the amp that gives you better sounding bass.. A lot has a to do with a few other factors as well.. first off your subwoofer.. the bigger the subwoofer the deeper the bass. Some woofers exturde, or flex differently depending on the quality and structure of the woofer.. 2nd is gonna be the sub box. different size boxes will give your sub diff. depths of bass. ... general idea is the bigger the box deeper the bass. But if your woofer is not supplied enough power a big box is useless.   With that size amp your best bet is too run a single woofer. Probably a 10inch woofer would sound the best.. but it in.75cub inch. sealed box.. should sound great.

THIS UNIT HAS NO SUB WOOFER AMP IN IT. THE ONLY WAY TO OVER COME THIS IS TO HOOK THE LEFT AND RIGHT FRONT SPEAKERS STRAIGHT TO THE SUB WOOFER AND THEN GO FROM THE SUB WOOFER BACK TO THE INPUTS ON THE BACK OF THE UNIT FOR THE FRONT SPEAKERS. THE SUB WOOFER THIS WAY WILL EXTRACT THE BASS AND THE FRONT WILL RECEIVE THEIR PART. THIS SOUNDS CRAZY AS HELL I KNOW BUT THAT'S HOW I GOT MINE TO WORK. THE OUTPUT FOR THE SUBWOOFER IS USELESS AND PUT THERE FOR YOU TO HOOK UP AN AMP FOR A SUB WOOFER. EVERYTHING HAS SHORT COMINGS, AND THAT'S THE ONE FOR THE AX-720.
