Question about Alpine SWR-1222D 12" Type-R Series Subwoofer Car Speaker

1 Answer

My subwoofer is cutting off. I replaced to fuse on the main power, and it works when I have the source on a very low volume level but when I turn the volume up, it cuts off. I have 1 alpine type R12 and a mono alpine 850 watt amp.what could be making it turn off and how should it be wired correctly.

You are probably running the ohms too low for the amp and its drawing too much current. Consult your amp manual for proper load level capacity and you can wire it accordingly. More then likely its only 4ohm stable bridged and your running it at 2 or less depending on if your subs have single or dual voice coils. Try connecting one pos speaker terminal to the other speaker neg then run the left ofer pos on one speaker and the the left over neg directly to the amp (series) I will raise the ohms (amp makes less power) but should not cut off unless the subs ohm are still to low, if this is the case you need a sub with a higher ohm rating or an amp wiht a lower rating...

What audio source you put into your Amp? you can lower the source volume also the amp volume to confirm, where the problem come.
Source input is also important whether you using low level or hi level input.

I get a red light on the back panel labeled power. No green light. I don't think the PV 600 is working but when I run the channel check through my Pioneer THX receiver I hear sound. Any thoughts?


The PV600 and PV400 have auto-on circuitry that turns the subwoofer on when a signal is presented, and turns off if no signal is detected for 15 minutes.

http://www.retrevo.com/support/Boston-Acoustics-PV600-Subwoofers-manual/id/522dj484/t/2/

Not knowing which Pioneer receiver you have I have dropped in the steps for No Sound from Subwoofer:

• Check that the subwoofer is connected properly, switched on and the volume turned up.

• If your subwoofer has a sleep function, make sure it is switched off.

• Make sure that the Subwoofer setting is YES or PLUS (see Speaker Setting on page xx).

• The crossover frequency may be set too low; try setting it higher to match the characteristics of your other speakers (see Speaker Setting on page xx)

• If there is very little low frequency information in the source material, change your speaker settings to Front: SMALL / Subwoofer: YES , or Front: LARGE / Subwoofer: PLUS (see Speaker Setting on page xx).

• Check that the LFE channel is not set to -80dB , or a very quiet setting (see Bass Peak Level

on page xx).

• Check the speaker level settings (see Channel Level on page xx).

Regarding the Large vs Small assignment of speakers, what they mean isn't so much the physical size but the ability to handle real bass. Large if Yes.

My Subwoofer Sony SA_WM500 was always burn the fuse therefore I had to change the STK, but now it takes off sound very low, How can I have back the high sound level? Zaruque Quimuenhe


It's no clear what you mean by "I had to change the STK", but if that means you have somehow defeated the fusing or place a larger fuse than it requires then STOP and shut it off. You might be risking a fire or more serious damage to the amp.

I would recommend you find a hands-on tech to look at it.

If you have resolved the fuse problem and now just have low subwoofer volume, you might want to track it back to the source and ITS subwoofer volume setting. There IS a volume level control on the sub, too. Turn it up.

The manual is here:

It comes on but no base sound and wont turn up


You have to fill in the details about what you're feeding it (the source and how IT's set up). It won't just >>create<< bass.

From the manual:

If you used the high-level (speaker) inputs and there
is no sound from any of the speakers:
• Check that receiver/amplifier is on and a source is playing.
• Check that powered subwoofer is plugged into an active electrical outlet and is switched on.
• Check all wires and connections between
receiver/amplifier and speakers. Make sure all wires
are connected. Make sure none of the speaker wires are
frayed, cut or punctured.
• Review proper operation of your receiver/amplifier.

If there is low (or no) bass output:
• Make sure the connections to the left and right “Speaker
Inputs” have the correct polarity (+ and –).
• Make sure that the subwoofer is plugged into an active electrical outlet and switched on.
• Adjust the crossover point.
• Flip the Phase Control switch to the opposite position.
• If you are using a Dolby Digital/DTS receiver or processor, make sure that the subwoofer adjustments on the receiver/processor are set up correctly.
• Slowly turn the Level Control clockwise until you begin to hear the desired amount of bass.

If you used the line-level inputs and there is no sound
from the subwoofer:
• Check that receiver/amplifier is on and a source is playing.
• Check that powered subwoofer is plugged into an active electrical outlet and is switched on.
• Check all wires and connections between receiver/amplifier and subwoofer. Make sure all wires are connected. Make sure none
of the wires are frayed, cut or punctured.
• Review proper operation of your receiver/amplifier.
• Slowly turn the Level Control clockwise until you begin to hear the desired amount of bass.
• Make sure that you have configured your receiver/processor so that the subwoofer/LFE output is on.

CHT12 speaker cuts out randomly have to turn off and on to get sound



Here is something you can try.

On your source check the output level for your sub.
Try setting up at a higher level, if at 1 set it for 2 or 3
Then adjust the volume control on the sub down to mach the speaker volume level.

Fuse on subwoofer keeps blowing


Subwoofers draw a tremendous amount of power. With the amount of heat generated by amperage flow and the movement of the voice coil, you may have burned out the coil. Do a resistance check across the coil. Easy check? Temporarily attach another speaker to replace that one. Use LOW VOLUME and slowly work the vol up,and, if the fuse does not blow, it's the other speaker.

New car speakers cut out when I turn up the volume.


You just have to check all of the speaker wiring.It's a wire touching somewhere and it will do that till you fix it. What it is is just where the negative wire which is the ground for your spreakers it's touching the positive wire which is know as a power wire.When this happends it lowers the frequency of the volume which will cause the speakers to cut out and volume level to drop.

Subwoofer works at high volume, doesnt work at low volume


You had the settings set incorrectly and overdrove it. The voice coil leads are burn't open. If you look at the little flexible braids by the terminals I'll bet they are black/brown and maybe even burn't in half. It's toast.

Yamaha YST-MSW10 subwoofer quits after about 10 minutes


This problem can be solved by either of the following:
1/ Modify the PCBA to prevent the auto shut off feature from working. This is done by adding a 20k ohm resistor across pins 1 & 2 on the timer IC6. This resistor will prevent the timer from turning off the amp. To do this, unplug the amp. Remove the 8 screws on the perimeter of the rear of the amp. Carefully remove the rear plate. Disconnect the speaker wires at the speaker and the front panel connection on the main board. Locate IC6 on the bottom of the main board. Solder a 20k ohm resistor (1/4W) across pins 1 & 2. Pin 1 and Pin 8 are noted on the board. Be sure to insulate the leads of the resistor to prevent contact with the board. See picture. Re-assemble in reverse order.
2/ Some 5.1 channel amps allow independent control of the volume for the subwoofer in their setup. Check your amp to see if you can raise the signal level going to the subwoofer to prevent the amp from shutting off. You can then dial back the volume of the subwoofer using the volume control on the front._436.jpg
