Hi, I recently bought a new Sub,a Pioneer TS-W305DVC.

A friend wired it for me and told me he had wired it in series.He then connected it to my amp andit was working perfectly so I went home and it stopped working.

I couldnt get it work again so I left it for a couple of hours and tried it again,it was working and then stopped.

I noticed my amp wasnt turning on anymore,I checked the fuse by the battery and it was blown.I bought more fuses but they continued to blow only until i disconnected the sub from the amp.

Could someone please help me with this problem,I dont really know much about installing sound....

thanks

The amp is a Pioneer 800w,not too sure about the model.

I dont think it was bridged...

It sounds to me that the speaker leads are shorting out somewhere, maybe inside the box itself.

I found out the model of the amp : GM X972.

Today I noticed that when I take out the face of the headunit,the amp's light stays on,but dimmed slightly.

It never used to do this.It would turn off as soon as I switch off the headunit.I also smelt something burning so I took out the fuse by the battery.

Im guessing that my amp is fried now???

Could something shorting or a wire come loose in the sub box have caused the amp to blow?

Most decks smell "hot" when you've been driving them hard for a while, but that's normal. They can get warm to the touch, but shouldn't be hot. Yes, shorting the outputs of an amp can definitely damage it. If you have a meter, just probe around and see what's good and what isn't. Disconnect the sub and see if the amp powers on, and if the fuse blows. Check the remote turn-on wire at the amp for voltage with the car on/off. I'd definitely pull the sub and see if the leads are exposed and could touch, and if so, insulate them.

I disconnected the sub from the amp,the amp turns on alright and doesnt blow fuses anymore but it stays on when I remove the headunit and the car is off.

Still smelling something burning from the amp,so Ive taken the fuse out near the battery again.

I also discovered that the sub wasnt wired in series after all,was wired in parallel.Could this have blown the amp?

Sounds like you need another amp. You didn't say if you checked the turn on lead for voltage with the car off, but regardless, if it smells burned, it probably is. If your amp is a two channel, your buddy might have bridged it, and then wired the sub in parallel. This would make it see a 2 ohm mono load, and would definitely fry it. Your best bet is just wire each voice coil to a separate channel, or a seperate mono block amp if your sub is still okay.

thanks

Well, okay, if you get a 2 channel, you'll have a left positive, left negative, right positive, and right negative for outputs. All you'll need to do is wire the left positive and negative to one voice coil, and the right positive and right negative to the other voice coil. This way, the amp will see the correct amount of ohms it's supposed to see (4 ohms per channel) and will keep it from blowing.
