SOURCE: Amp is on, Subwoofer works, but no sound.

here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem

SOURCE: Hooking up a new 8" woofer speaker to my amplifier

If I'm reading the amp manual right, you should be able to connect the amp in 3 channel mode. To do this:

  • Connect both left door speakers in parallel to Ch A Left.
  • Connect both right door speakers in parallel to Ch A Right.
  • Bridge Ch B and connect it to the new 8" sub.
  • Set the Ch A LPF/HPF to HPF.
  • Set the Ch B LPF/HPF to LPF.
This should allow you to run all 4 door speakers and the sub from the amp. It will also automatically route non-bass to the door speakers and "only bass" to the sub.

Hi ive searched for a manual on this as i was bored and i can tell you you have to.
press function repeatedly until clock appears.
When it does press < or > to select a segment of the time eg hours or minutes.
then press ^ or down to increase or decrease
Hope this helps.

Check all ground cables from your truck's stereo and amplifier as well. Sometimes when ground cables get loose you hear those thumping noise in your subs. GOOD LUCK!!

Do not continue to put new fuses into the amp until you have figured out what is causing the problem. It will only increase the chances of causing more damage to the amplifier. I have been repairing car and home amplifiers for over 18 years and have a lot of experience with Pioneer amplifiers since I work at an authorized Pioneer service center.

This post will be long, but if you bear with me and forgive my long-winded answers you may be able to determain your problem even tho I really don't have enough information to figure it out yet. If not, we can get a little closer with more information.

Does the amplifier blow the fuse as soon as you connect power to it, or as soon as a new fuse is put into the amp? If so, the amplifier has some shorted components in the power supply. They have a bank of mosfet transistors in the power supply that sometimes get shorted when the amp has been pushed beyond it's ability, or just from a random part failure, or if the impedance of the speakers is too low. Your speaker is a 4 ohm speaker, if it is at a lower impedance than 3 ohms when measured with an ohm meter then it will need to be replaced. Even if it still plays, it is too low of a load for the amplifier and will cause more current to go thru the amp than what it was designed for. If you are using more than one speaker and have them bridged it will do the same thing. This amp is rated at 4 ohms bridged and 2 ohms per channel stereo. When you connect 2 speakers together and then bridge them they become a 2 ohm load which causes double the amount of current to flow thru the amp. It was not designed for that. Sometimes you can get these component failures just because there may be a solder joint or two inside the amplifier that is cracked and not making connection very well and this can cause components to short out because they are not operating at the proper voltage.

If your amp blows the fuse only after it has been turned on by your head unit, you will most likely have a blown channel. This would require the replacement of the output transistors of the bad channel as well as a few resistors and sometimes a few other parts.

If your amp will turn on and play for a while and then blow the fuse at higher volume levels or after a long time playing the problem can be either a bad speaker at a lower impedance or one or more components that are breaking down after they get hot or at a certain volume level.

As you can tell by now there are many reasons that an amplifier can blow the fuses, and figuring out just what the cause is can sometimes be a difficult task. It may require that you have a multimeter to do some checks on the amp and a power supply to power the amp on a bench so you can do those tests.

If this information has not helped you to determain the problem, please give me as much information as you can about how you are using the amp. How many speakers, where they are connected, at what point does the amp blow the fuse, and anything else that you can think of that may or may not be important. You never know what might give a better clue, too much information is always better than too little.

Thanks and good luck,

Dave

I have a pioneer GM-X524 amp connected to a TS-W253C subwoofer and it isn't working. It has 12v power to it and a solid ground, but the power light wont come on and the sub isnt working


there should be 3 power related cables connected to the amplifier:

1-From battery to amp via fuse (positive)
2-From chassis of car to amplifier (negative)
3-From head units (power continuous) (blue or blue/white cable) to the amplifiers remote connection.
this connection enables the amplifier to switch on when the head unit is switched on and off when the headunit is switched off.
I hope this helps and let me know if I can further assist you.

Is my 1200 pioneer amp a good match for my 1200 watt pioneer sub


this is too close, your speaker wattage is alway's higher than your amplifier's wattage alway's to be safe because the hard pounding will make the speaker work harder, and this will cause your speaker burn out easily, though you can adjust your amplifier anyway's

No Sound from Subwoofer


The original Pioneer subwoofer has its own amplifier built in to the speaker, so the only cable required on the original speaker is a single RCA cable. To connect a different brand subwoofer to the Pioneer you will have to make sure that you have a subwoofer with the same specs. It will need its own built in amp to work, as you can only connect it with one RCA

Amp connection to pioneer tsw307d4


First of all check impedence of the subwoofer and how many voice coils it is. Go to www.the12volt.com click on subwoofer wiring diagrams then you check the load that your amp is stable at. Then wire it that way. Easiest way is to print out the diagram then take it actually out to the sub and box for reference.

I need instructions connecting my car subwoofers


Bridging your amplifier @ 4 ohm will yield the most power.... with the subwoofers you have.
You must wire them in Parallel.
Positive on both subwoofers to + on amplifier.
Negative on both subwoofers to - on amplifier.
The lowest impedence possible with 8 ohm woofers is 4 ohms.

Subwoofer


Most AV receivers do not have a built in amplifier block to drive a subwoofer, and merely provide the subwoofer output channel at line voltage. Thus, a powered subwoofer is required. Does the subwoofer require mains power? From your description, I'm guessing it doesn't. If not, it does not have a buit in amplifier, you will need to purchase a monoblock amplifier, which is just a mono amplifier with a volume control, no tone controls or anything else. Make sure that the amplifier power rating is as close as possible to the subwoofer power rating, as it is quite possible to blow a speaker by using an amplifier whose power output is too low, by overdriving the amplifier , and putting DC through the voice coil when the amplifier clips. If it does require mains power, it will have an amplifier built in, but does not have line level inputs.
