Re: help ASAP Plaese
Are you saying you connected the sony output jacks to your subs directly without any other amp? Are the sub outputs powered? Or line level? Are the subs powered or direct? need some more info please. and post the Manual here if you can. Thanks

Ok. Simple test to check if your subs are blown. Hook up speaker wire and simply touch each wire to each end of a new aa battery. You should hear like a sizzling static sound from the sub and it should jump slightly if its good. If subs are good you may be having issues with the connection terminals or worse. And it could simply be the audio connection from the stereo or the audio wires need replaced. Possibly replace the stereo or amp. So many more options but this should get you headed in the right direction.
Hello.... I am sorry to hear you are having problems. The reason for this is that since you have a stock stereo, the shop (or person) whom installed the amp and subs used a line out converter. What this part does is allows the connection of RCA cables to the factory head unit. Almost all bass signals are always in stereo, so since you were only hooking an amplifier for just subs, you can actually just connect to just one of the rear speakers instead of connecting to the right and left. Just makes the install a little quicker. There is nothing wrong with this as I usually do the same thing in our shop. However, if you are going to be using the balance control, then you will need to go back to the shop and have them hook the converter up in stereo (to both rear speakers). Hope this helps!
you may need a new head unit. it sound like you have lost the fron rca hook ups on your unit. common prob. usually cause by a surge traveling then the rca cables. i myself have had this happen and there is nothing you can do to the unit to fix it.
If the sub isn't working, you won't get a pop. All you need is a small speaker. Don't need a sub, you just want to test the sound. I recently blew 2 subs, no smoke, no smell, no sign of being blown. Absolutely nothing from the subs.... In the past my sub locked up. You can take your sub out of the box and hook the + and - to the battery to see if you can get the sub to pop there. I believe a small box will push a sub into a deep excursion to the center of the cone. I have 2 lanzar VW12D's that just quit. I hooked a 6 x 9 up to my amp and low and behold I had sound! Try that and see what you get...
It sounds as though either the sub or amp is blown. When an amp blows quite often the light will still light, but the internals are trashed. The only surefire way to tell whats going on is to use a Digital Multi-meter to check the impedance of the sub, and the voltage at the amp. You can get a multimeter as cheap as $10 at most autoparts stores, Radioshack, Sears, etc...
Also, always post brand names and model numbers, because more info equals more help.
The amp is rated to run a 2 ohm load on each channel. To do this, connect the voice coils of one sub in parallel (tie both "+" on the sub to each other and both "-" on the sub to each other), then connect that sub to one channel of the amp. Repeat this process for the other sub and connect it to the other channel on the amp. The subs will be in stereo and the amp will be outputting it's maximum power.
Well if you took off the cover on the amp and nothing seems to be burn't, check the voice coils on the sub. It's possible the voice coils have separated and is causing the amp to short it self out due to ground error. If that doesn't help let me know and I'll tell you the next step.
These subs are dual voice coil I'm sure...make sure they are putting a 2 ohm load on the amp total, and also set your gain and frequency setting right. Set the frequency around 85 or 90, make sure the lo pass filter is on. Turn the gain ALL the way down and turn your stereo to the point right before your speakers distort....then slowly increase the gain until the subs are playing at full volume. This should not even be close to all the way up, and the subs should sound accurate and bold. Turning them past this point will cause distortion, in which case you should back off the gain a bit. Distortion causes power to cycle through the amp very rapidly and can cause blown subs and blown fuses.
If you do not know how to wire both subs for a combined load of 2 ohms, please let me know what type of subs you have.
