SOURCE: sony 1200 watt amp

What kind of deck to you have? Sometimes there's a setting for the subwoofer output that has to be turned on. How is the deck hooked up to the amp? Be sure of the normal things: -Make sure the sub is connected in side it's box -Make sure the RCA cables didn't come off the deck -Check every connection! Let me know and be sure to leave feedback or I don't get paid.

SOURCE: apline mrv-1000 2 infinity sub

RMS power at 12V 20Hz-20kHz
2 x 100W @ 4 ohms (0.08% THD)
2 x 200W @ 2 ohms (0.3% THD)
1 x 400W @ 4 ohms bridge (0.3% THD)

That amplifier is not 2 ohm mono stable in bridged mode (assuming subs are SVC 4ohm).
It is seeing too much resistance and overheating. Thermal overload protection kicking in.

The phase switch allows you to switch from in phase to 180* out of phase. This feature is not to taken as written in stone. In some rooms, or locations of a room, the output will sound louder/better either in phase or out of phase. So there is no correct setting. It all depends where the sub is located and the acoustics or shape of the room.

Phase is term that describes multiple characteriscs and behavior of a speaker system.

Phase alignment: The vertical alignment of the voice coils of all the speakers in a speaker cabinet, so that all signals reach the sweet spot at the same time.

Crossover phasing: If one or more crossover slopes are of a different slope, then the speakers would not fire at the same time, causing delays in response.

Reverse polarity: You may reverse the polarity of a speaker to make the speaker fire inwards instead of outwards to improve alignment with the other speakers in the system. This is very common in tweeters circuitry. As for woofers, if the polarity is reversed, there is usually a cancellation of bass, to a degree.

SOURCE: Alpine PDX1.600 amp cuts off

Make sure there's no missmatched impedance. If your sub running 2 ohms then your amp has to be 2 ohms stable. Does the amp blow fuses or get really hot? If it does it can be a fire hazard and I would recommend taking it out of your car. It could be that you don't have sufficient grounding. The grounding needs to be very close to the amp and the paint needs to be thoroughly scratched off. Otherwise could be a blown transistor within the amplifier, you can check this by opening up the amp, running a multimeter and testing the transistors for resistance.

what wattage are the subs and amp? if your subs are more wattage than your amp, your amp will blow fuses as cant handle the output to your subs. for example. you have 2 500 watt subs and a 300 watt amp, that is no good as amp isnt powerful enough. if you have 2 500 watt subs you need at least a 1200 watt amp to power them both. 200 watt more than the combined wattage of subs as amps should never be turned up to max as they tend to blow and overheat more quickly. 80% volume on amps is reccomended by installers and manufactures.

Which amplifier i should use with JBL CS-1205T


this sub woofer tube has a rms rating of 275 watts... try using a kicker or orion 600 watt mono amp to run this. the brand name is what tell you about how good an amp is for instance the names i just mentioned rate their amp by standard play frenquencies where as other lower brand names rate their amps by the max out put on certain subs at certain frequencies which may lower their impedance and create more power although you will never play your sub at those frequencies. as for the max power of your sub of 1100 watts that is more than like only at a certain frequency so always only double your rms rating of your sub to find max power handling.

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.

Well when you blow a sub it can definantely short your output fets in the amp.

ELA 500.I


While I don't have any first-hand experience with either Bazooka amps or Memphis subs, this review pretty much says what I initial thoughts were. The amp will do the job without much fuss, so it mainly depends on whether you can get it for a good price.
BUT........
There could be a issue with your sub. According to Memphis, your sub (assuming it's the single voice coil version) is only good for about 250W RMS (let's ignore peak power for now). The ELA500.1, on the other hand, puts out 375W RMS at 4 ohms. You could very easily overpower your sub with that amp.

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!!

Powers on but no sound


Check the main amp fuse under the hood, even if it looks good just change it. Often times that light on the amp can come on just from the power amp tunon wire. Try a friends subwoofer box just to make sure the connectors on your box are good, and if that doesn't work then give me some more details....year/make/model of car, what kind of sub, what types of things do you see on the side of the amp....is there a green light as well as a red light?
