Hi,
If your description is to be taken literally, and smoke did indeed come out of the speakers, your output transistors have shorted out, and put the full power supply voltage and current through your speakers.
The amp and the speakers will need to be serviced. The speakers will need new voice coils at the least.

I have a pair of linn komponent 104 speakers i was wondering if i can add a sub woofer to my amp to give the sound more bass as the speakers dont have a good bass sound


The Linn's should have a good bass, clean & tight but not boomy. Have you got them correctly phased? Red-to-red, Black-to-black? Bass is killed if one speaker is anti-phased.

I have two B215 600 watts speakers. Smoke started to come out of one when it was in use. I continued to use the other one, and about an hour later, the bass on that quit working. Any help with...


Sorry, those speakers are rated at 250 Watts RMS continuous, NOT 600. The speakers are nominally 8 ohms. The PMP6000 will deliver about 250 watts RMS to an 8 ohm load so the speakers should be able to take this as long as you had one per side and NOT using bridged mode of the PMP6000. It is possible that you fried the amp, although the PMP amps have a speaker protection network that shorts the output should the amp hard over. It is strange that you could draw smoke with the setup. Hopefully you were not generating very low frequencies that were below what the speaker could handle OR that you did not crank up the bass with the EQ such that frequencies below the speakers rating were sent at high levels. Your speakers are rated for a low end at 55 HZ. You should have the eq cut the gain below that. The leftmost EQ (50 Hz) should NOT be higher than center... if you boost that one, you likely will be buying new speakers. If you need power below that, then you need to be using subwoofers. Hopefully you haven't damaged the PMP6000... I assume that was the amp you were using, although you haven't stated that. At this point, unless the stuff is under warranty, you nee to open the speakers and see what has blown... could be the woofers or the crossover network...Use an ohmmeter to check the woofer DC resistance... should be between 7 and 9 ohms. If it is open circuit, the voice coil is blown.

I have a kicker 750.1 amplifier. I was playing it one day pretty loud and it cut out once the bass hit and started smoking.The gain was up about 1/4 and the bass boost was about half way. what could of...


I would say that your subwoofer Or speaker leads have shorted out...when the bass hits as you say it drives the amp hard but if it is trying to dump power onto a shorted speaker or speaker wires it will blow the output power transistors not to mention other vital components of the power amp...i suggest you test your speaker leads with a Multimeter on the ohm setting before connecting a repaires or another amp.. to make sure there is no short on the leads and that the resistance is around 4 ohms or so depending on how you have your drivers wired...but anything lower than 2 ohms will cook an amp! you can normally pick up a meter from anywhere for around $10..

Bass speaker moving in out more then normal


If you can't hear the difference maybe the bass frequency which is moving the speakers is below your hearing range.

I think you may have a "loudness" button on that amp -- if you do, turn off the loudness -- this is a bass booster.

But, in general, bass speakers are designed to move in & out a lot. They have to move a lot of air to produce the bass sound.

I turned my 15" L7 kicker and smoke started to come out the box


As stated before, knowing the impedance of your subwoofer would really help the situation. Either way the link I have provided is to your subwoofers manual (Incase you dont have it)

But since you have said it has smoked, if it still works I recommend turning the bass boost down (Bass boost causes alot of heat within the subwoofers voice coil and even within the amp itself and should never be maxed out.)

Here is a link to your manual for the subwoofer.
http://www.kicker.com/sites/default/files/SoloBaricL7Series.pdf

So as a solution to your issue, keep your bass boost turned down. You should almost never need it if you have tuned your amp correctly (You have a very serious subwoofer there)

Consider yourself lucky if your subwoofer is still working without issues.

Speakers not working


The black/green/orange connectors go into the corresponding color ports in the back of the computer, but you computer have to be able to support 7.1 or at least 5.1 audio. If it can't you can buy a separate sound card from Creative that does.

Dual voice coil speakers


best way to do this to preserve your amp and speaker is to wire the speaker Voice coils in series.

VC1 = Voice coil 1

AMP + to VC1 +
VC1 - to VC2 +
VC2 - to Amp -

Set you amps bass gain down very low. Crank up the volume with a bass test audio track. Turn the switch to LPF or Low pass filter. Adjust a LPF to about 60 hz Adjust the bass gain up until your Sub begins to sound sitorted or choppy. Then tune the bass gain just below where it distorts. Then you are set.

Hi Trim God,

 

I do not reccommend that you push the Pioneer speakers over 100 watts.  The jenson will already drown the car with bass through your pioneers so much you will want to turn off the bass boost when playing some low bass hip hop songs. It changes from one venue of song to another, so I just keep the jenson bass boost off and use my head unit to adjsut the sound to fit my listening prefences. I am telling you man, you will be blown away .  Hook up the pioneers straight to the Channels,. do not bridge.  I put Subs in my truck though.  I used the Pass output to send the audio to me Jenson 2 Channel 600W amp. I drive one 10 inch enclosed JBL Class A/B Sub. I bridged the output of the 600 W amp to the 10 inch sub  in my Z28.  The pioneers never get drowned out.  I did smoke my 2 channel Amp one time. and also took out a MTD 10inch sub. I am talk shooting flames and smoked the whole car up. I think if you bride the XA4150 to the pioneers, you will have the flaming smoke problem in no time.
