What is the RMS on the Sub?

Posted on Sep 30, 2007

  • Patrick Craig Sep 30, 2007

    Ok if the sub takes 2000 watts to run it properly I can sell or your can go and find DB Drive PDT2000.1D. It is a pure power amp and 1 Ohm Stable. That will pus that sub wonderfully.

How to splice a sub-woofer to speakers

Normally the sub woofer is driven by a separate amplifier, unless the main speakers, such as in a pro audio setup have a special LF out set of terminals on the back of the speaker cabinet, in this case there is a hi powered low pass filter, fitted in side the speaker to route the LF energy to a sub woofer. Else you need a line lever LF signal spliter and a power amplifier to connect a sub woofer.

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 have a rockford fosgate 1001d and 2 audiopipe dvc 12s need 2 know how wire speakers

Check to determine if your sub woofers are DVC 4OHM or DVC 2OHM SOLUTION 1 If your sub woofers are DVC 4OHM then, from the positive (+) of the amplifier run your cable to the positive terminal of voice coil 1 on sub woofer 1 then continue to connect all the positive voice coils together on both sub woofers. Do the same for the negative from amplifier to all the negative voice coils of both the sub woofers. RECAP: all positives together on the positives and all the negatives together on the negatives. This will give you a 1 OHM load to the amplifier making it deliver all its power but will also run hot. So if you are living in a hot climate take care. SOLUTION 2: Connect the negative on voice coil 1 to the positive of voice coil 2 on sub woofer 1 Do the same for subwoofer 2 now you should have a free negative and a free positive on each of the sub woofers. connect the free positives together and follow through to the positive on the amplifier. do the same for the free negatives sending them to the amplifiers negative. This will give you a 4 OHM load to the amplifier. Not full power in this mode but the most stable working condition for your amplifier. SOLUTION 3 If your sub woofers are DVC 2 OHM then you only have one reasonable wiring solution. Connect like solution 2. This time because of the DVC 2 OHM sub woofers you would have a 2 OHM load to the amplifier. This is also a stable load for the amplifier and does not generate to much heat and still deliver over 50% to 70% of the amplifiers power. good luck and drop me a line if you still have doubts. dreamsystems

My sub make a strange noise. It doesen't work anymore.Tks.

Strange noises can come from your amplifier or the sub itself. The most likely cause of the strange noise is the speaker just before it dies! If you have been using the sub-woofer at high volume levels then you probably have damaged it. Try testing the sub-woofer using a multimeter(on ohms setting) it should give you a reading from 8 to 4 ohms. Sometimes they may give readings as low as 1 ohm. When testing the speaker/sub you should hear a soft scratchy, thumping or clicking sound. This indicates that the speaker may still be working. If you don't have a multimeter try a 1.5 volt battery (say a AA), DONT USE HIGHER VOLTAGE BATTERIES they may damage the speaker! You will hear a clicking, scratching etc sound from the speaker which may indicate that it is still OK. If the speaker seems OK the problem may be in the amplifier, which I suggest you bring to a professional repairer. When buying speakers and amplifiers make sure the power handling of the speaker is equal to or greater than the amplifier output power. This should stop speakers from getting damaged. Make sure the speaker and amplifier specifications are rated in the same manner ie RMS PMPO Peak. A 100 Watt PMPO speaker will not survive the output of a 100Watt RMS amplifier!

Can I hook up 2 single coil subs at a 2 ohm load on my sony xm-1252gtr?

If your sub woofers are SVC (single voice coil) 2 OHM each, then connecting one to each channel would make the amplifier run in 2OHM stereo Then again, if your sub woofers are 2OHM each, it would be better to connect both together in series and connect them to the BRIDGE specified speaker terminals of your amplifier making it run a 4OHM load into one channel. This will give you all the power the amp can give and still run stable. A 2OHM load into one channel will likely damage your amplifier. Do not forget to set the LPF (low pass filter)on if you are going to use the amplifier to run sub woofer/s. dreamsystems

Mirage LF 150 Sub Woofer. sub not working

within the sub amplifier is an electronic amplifier, that is shorted and blown a fuse. This is all internal. If you can dismantle this module, I suggest do so and any electrical/electronic individual will identify the part needed. you could also check on a replacement module-complete.

Amp light is on but no power to my subs!

Hi There.

When you say the 40 Amp fuse blew. Was it your mains battery fuse or was it the fuse on the amplifier? If it was the fuse on the amplifier then you may have hurt the amplifier. The Kenwood KAC-8101D is a 1000 Watt monoblock amplifier. Therefore if you say that 1 of your woofers is not playing, then it is almost certainly blown if you are sure it is connected correctly. Try disconnecting it and only running the woofer that tries to play. If this woofer is still working correctly, you will notice a drastic drop if the sound of your bass. The reason for this is because you have changed the impedance load on your amplifier due to the fact that the other woofer is not working. Have your working woofer checked and replace the faulty woofer then you should be banging again.

Hope this helps!!
