Car subwoofer wont play loud

MTX subwoofer, pioneer amp. Sub playssound, but sound level is low coming from sub. Worked fine but now the sound level dropped. Connections are good, rechecked adjustments, gain, head unit etc... all looks good. When you turn the gain up it gets louder but not even close to where it used to be.I usually have it set at normal, but if i turned it all the way before it used to shake the car. now even with the gain all the way up its not even to where it was at the normal setting. If you take the rca's at the amp and unplug the left no change. unplug the right. no sound. so i checked the left and right rca's and plug in each one into the left input i get sound so i know both left and right rca's work. just no power behind it anymore. Im guessing the prob is with the amp, but i dont know if its a fuse or if its going bad or what.

You blew up a channel in your amp. Being that it's a Pioneer amp, I would throw it away and get another.

No sound from subwoofer


From somneone on the AVS-forum I got the tip to set the front speakers to small. After checking this (it was set) I looked after the sub (a Fostex PMsub) again and turned the volume really high - and now it works! Of course I have tested the sub on another output (other amp and zone2-out on the Onkyo) and it worked with a relatively low setting. So it seems, that the sub-out is just very low level, but working OK.

You are def overheating, If the ohms rating of the subwoofer is too low it will cause this same thermal over heat. If you have 2ohms in sub and a 4 ohms stable amp, you will overheat. Check the ohms rating of the sub to make sure this is not the problem

Had the subwoofer tested at an audio shop but they wanted to sell me a woofer. It makes no sound at all. A power issue? there was no problems with the 300 watt Kicker amp.


if the speaker cone moves it should produce some sound if it doesn't move when power is applied then the voice coil is frozen.

not really a power issue unless its a "powered sub" and if that's the case then you should not be running in high level sound using speaker wire (especially off a 300 w amp) but instead a low level signal via RCA cable.

Subwoofer


Your overdriving the Subs and burning up the voice coils. Its really not worth fixing. It almost costs the same to fix as to buy a new one. Set you Amp gain down low. Then crank up the volume with a bass test. Slowly crank up the gain until you get some distortion. Then reduce the gain slightly. You will be set then to crank it up to the distortion level and not blow you speakers. Open a can of whoopass on anyne the cranks up on your gain. It will be costing you another set of MTX's.

RCA Problem


You need an active subwoofer input in your amplifier.Which amplifier you are using? Only latest pioneer amplifiers has active sub input and sub output which can be connected to subwoofer.If you dont have active input then you will have to connect it the way you did in old player.
