Question about Sony XM-2150GSX Car Audio Amplifier

Subwoofer Wont Work

I have a 2000 BMW 740i. I recently bought a sony xplod sub and amp. I went to a local audio store and had them wire and hook it up. 5 Min into using it it stopped, I opened the trunk and there was smoke coming from the box. Sub fried. I went back and told them to replace it which I did and the same result occured. So I go buy a new JBL amplifier, a new Kenwood sub and hook it all up and I start to smell a burning smell again (which I think is the coils burning). Does anybody know why this is happening? I have a built in amp in my car but idk if that has anything to do with it. Also maybe theres a slice in the wire and its touching metal? Any ideas?

Re: Subwoofer Wont Work

If the connections are correct...?
then it doesn't sound like theres a problem with the amp.

make sure the amp is not to powerful for the sub?
eg: 1000w amp, 500w sub.

Sounds stupid but it happens.

make sure the gain / volume is not too high!

if your BMW has a totally sealed, metal boot area this doesn't help.

Check your subwoofer for resistance. It is more likely you blew a sub than a channel on the amplifier. If your subwoofer has no resistance, which can be checked using a multi-meter, then it is blown.

Hooking sub up

Hello missywarden,

According to the specifications, the amp is capable of "tri-mode" operation, that is, running normal speakers on the individual channels while also powering a subwoofer in bridged mode.

Your sub needs to be a minimum of 4ohms and should be relatively efficient. I'd look for a sub that has an RMS power range of from about 75 watts up to a maximum of 250 watts.

The sub connects to the leftmost speaker terminal (positive - right channel) and the rightmost speaker terminal (negative - left channel).

It's not going to be a really loud subwoofer. The power is 360 watts RMS which will be shared by the normal speakers and subwoofer.

Hope this helps.

How to measure watts

You need a Volt Meter and an Ohm Meter. P = VI & I = V/r, so Power = (Volt^2)/Ohms .

You can get the ohms by hooking them up to the subwoofer input wires, and you get the volts by hooking up to the amp output terminals/wires. Although, amps will put out different voltages for different frequences, this should give you ballpark estimates.
