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.

Yes....hook one up to the left channel and one up to the right.....once everything is wired up.....keep gain down on amp and turn stereo on.....turn up stereo with amp gain down to right before high end speakers start to distort......then while its playing, turn amp gain up about 1/2 way. close your trunk and hop in drivers seat....sound gd????? You might have to adjust level on amp and bass on head unit to taste.....Be careful though....pioneer subs are only rated around 300 watts continuous.....dont want to blow them...gd luck....
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.
This is caused because the stereo you have put in, is a high power output, or higher than the factory and puts that extra power into the factory amp systems causing the amp to surge the power to the speaker resulting in the pop sound,most newer cars use a stereo system without an internal amp so as to reduce heat and a external amp in usually under a seat or dash and a high power stereo boost the output of the amp.
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.
According to the specs for the xo 1945- the output is; 50W x 4 Max Power Output , and I do not see a pre amp output listed. So I think to connect subs, you will need a separate AMP.
The way this works; the rear speaker wires from the xo 1945 hook into the Add-on amp, for example a 4 channel amp. In a 4 channel amp, the rear speakers come off two of the channels of the add-on, and the subs come off the other two channels. There is also the option of bridging two channels for more output power to ONE sub.
You did not mention what size sub(s) you were thinking of adding, but keep in mind that the ox 1945 puts 50 watts MAX per channel. So, if you add two 12" subs and a 1500 watt amp to drive them, your total sound is going to be very uneven.
If you go on line and look up auto audio or amps, you'll get a good idea of all the Sub and amp options that are available.... Hope this helps.
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
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.
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.
