Amp and Stereo hooked up, no sound coming from the sub
I hooked up my sub to an amp and had it working for several days. It stopped working and i noticed that the ground wire no longer sparked when it touched metal, i stripped it down away and it worked again. About a week later, i got the same problem but this time when i stripped the wire down, it didn't help. I got a 4k watt amp and a 15" Eclipse. The amp turns on but there is no sound from the sub

Re: Amp and Stereo hooked up, no sound coming from the...
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.

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!
the problem sounds like your new sub is drawing to much power and your amp can not handle it. bridging the amp is a good way to get the full power out of your amp. But it isnt always suggested, my solution is to get a bigger amp. I install stereo systems for a living, and i tell my customers that it is smart to get an amp about 100 more watts then the rms rating of your subwoofer.
Check the 12v wire running from the battery to the amplifier. Also the sony explode is a garbage subwoofer compared to the Alpine.. sony (they say 1200w max but its more like 100w to power the thing) Amp could be going. Is the amplifier hot when running. If there is a burnt smell comming from the amp, its the amplifier
IF YOU HAVE THE SAME AMOUNT OF CABLES AS SPEAKERS HOOK THESE UP TO YOUR AMP THEN SUB TO SUB OUT PUT ON YOUR AMP WITH A SUB CABLE OR PHONO THAT REACHES FROM AMP TO SUB.SET AMP TO ALL CHANNEL STEREO OR MODE THAT SENDS STEREO TO ALL SPEAKERS,ALSO SET SPEAKER SIZE IN SETUP OF AMP TO SMALL AND SUB OUT PUT TO SUB ONLY.YOU SHOULD GET MUSIC AROUND THE HOUSE.IF SOUND IN SAY BEDROOM IS NOT AS LOUD AS BATHROOM USE THE TEST TONE TO LEVEL OUT EACH SPEAKER.
if you are sure its the amp. the problem is internal. but if your not sure, try a different stereo or source of sound to the inputs of the amp. if there is still no sound than it is the amplifier and it could be a number of things.
Any idea how this is all wired up? I think what they have may used is an 'RF modulator kit' to get the signal from your stereo to the amp. These are commonly used when factory stereo's don't have any outputs on the back of them for adding external amps. Even so, when you unplug the RCA cables there should be no signal coming to the amp & no sound coming out of the speakers/subs that are subsequently connected to the amp either.
Check the wiring between the sub and the amplifier. That's seems to be the only thing left that could cause a problem. If it's shorted to ground or pinched so the conductors are shorted together, it could cause the symptoms you listed.
What kind of car? What kind of system? More details will help me assist you better.
If it is an aftermarket in-dash stereo, it sounds like the blue/white wire is not hooked up correctly. This powers up the car's amplifier and lets the sound through.
