SOURCE: sub woofer is blowing up and down even when head unit is off

This is an internal power supply failure - most likely a failed capacitor or bad ground trace..
Your amplifier requires repair.
To verify this - remove the RCA cables and if the "heartbeat" is still present - take the amplifier to a local repair shop that specializes in car audio and tell them your symptoms.

I have AIWA NSX-RV85. The sub-woofer surround tore leaving just the cone. When I play, The woofer just makes a rattling sound coming out of vibrating cone.Any advise on how to fix my speakers.Thanks


Refit the rubber, you can find itbon eBay, its called reconing actually in this case the cone is the inlybpart wich you dont want to replace... The rattling is beingproducer due to the fact the rubber normally holds the cone ibto positionering over the coils. This rattling is not good can defect your cone. So dont play it roll you got a new rubber fitted!

How to change the connector on subwoofer of coby 5.1 cs-p92 so that it can play with Sony str dh750 receiver


Before you cut any wires, make sure the sub woofer can handle the power from the Sony. Is the sub powered? What are speaker specs on the Sony . Is the output jack on the Sony meant for an unamplified sub? You have to know the answers to all this so you won't blow up the Sony and/or the sub woofer

My powered subwoofer no longer works through the receiver


if you have your front and centers set to 'small' you want your Bass out to be subwoofer only, and the rca jack labeled 'sub out' is the only place to connect your sub to if you want to control the frequencies with your reciever. I dont know the brand of your sub, or the inputs on the back of it to advise you where to connect, but it sounds like it worked for you at one time, but suddenly it does not

Subwoofer is not playing


It is hard to say. The sub-woofer has its own amplifier, although it is supplied the sound data from the main amplifier. It could have a problem with the battery power circuit (Sub-Woofer Amplifier Connector Pin 6, LIGHT GREEN/VIOLET) or it could have a problem with the GROUND circuit (Pin 2, BLACK/LIGHT GREEN) Or it could possibly not be receiving the signal from the main amplifier (Pin 7, BROWN/ORANGE "+"), (Pin 8, RED/BLACK "-"). Or it could be that either the sub-woofer speaker is blown, or the sub-woofer amplifier is defective.
There is also a "High Audio Mute" circuit that connects between the main amplifier and the sub-woofer amplifier.

Can i power 2 12 subs a rockford punch z and a xplode with this amp i found all this **** in my garage and i need to know if it will power all this


First of all. Using two different kinds of sub woofers, is not an option, as these two sub woofers have different specifications and you should never mix sub woofers. Now the better choice from the 2, would probably be the Rockford. (cant be sure without knowing the models, power handling is also a factor in how well either of the sub woofers will play, but Rockford as a rule makes better sub woofers than Sony does) In my opinion, both the sub woofers deserve a better amplifier than what Boss has to offer. However to connect either of these sub woofers, you would need to determine how many voice coils it has and how many OHM the voice coil/s are. If it is a DVC (dual voice coil) and each voice coil is 4 OHM or 2 OHM, then you can connect one voice coil to one channel of the amplifier and the other voice coil to the other channel of the amplifier. If it is a DVC 2OHM you can also connect it wired in Series/Series to give a 4OHM load and should be connected to the BRIDGE dedicated speaker outputs of your amplifier. If it is a SVC (single voice coil) and it is 4 OHM, then you can connect the sub woofer to the designated speaker outputs of your amplifier that states BRIDGE. DO NOT run the amplifier in BRIDGE mode at 2 OHM as this will probably damage the amplifier. dreamsystems

I lost my remote control and I want to turn on my sub woofer manually through my receiver. How do I turn on my sub woofer.


Perhaps I misunderstand the question.

Depends on the Sub. Most powered subs will go into standby mode in the prolonged absence of a signal. Then they wake up when you play something.

Or are you saying you need to Enable the Sub, as in setup? Remote probably required for anything like that.
