These subs are dual voice coil I'm sure...make sure they are putting a 2 ohm load on the amp total, and also set your gain and frequency setting right. Set the frequency around 85 or 90, make sure the lo pass filter is on. Turn the gain ALL the way down and turn your stereo to the point right before your speakers distort....then slowly increase the gain until the subs are playing at full volume. This should not even be close to all the way up, and the subs should sound accurate and bold. Turning them past this point will cause distortion, in which case you should back off the gain a bit. Distortion causes power to cycle through the amp very rapidly and can cause blown subs and blown fuses. If you do not know how to wire both subs for a combined load of 2 ohms, please let me know what type of subs you have.

Why does my spa 500 amp blow a fuse every time I hook up my 15" lanzar sub to it


Because it's drawing more power than the fuse can handle get a fuse with a higher rating. A 100 app fuse worked great for main power with my setup 760w amp a 15"sub 2 10"subs and a 12" sub. Also my amp had 2 30amp fuses on it one for each channel but I ran everything out of one channel.

The amp cut off and is not coming back on


Sounds like you burned out the sub channel usually due to having a sub the draws more watts than the system can push, effectively blowing a capacitor or node within the internal motherboard of the AMP.

Mission m-cube sub fuse keeps blowing


If you have replaced with the correct rating and the fuse blows off then you will need to check for higher current drain in the sub woofer or the network. After replacing the fuse load up the subwoofer slowly, reduce the bass and as you increase check at the point the fuse blows off. Now we need to analyse if the rating of the amplifier you are using is rated for the subwoofer. If your subwoofer has a higher rating you can increase the rating by about 25% and check again. Some amplifiers give a very higher voltage on full bass which could result in such a condition. Moderate this and check again. If the fuse stays Ok you can continue with this new rating.Otherwise the output of the amp at higher volume needs a confirmation. Hope this helps. Good day

KAC9103d been running great for a year, factory refurb. for a month been losing sub output. checked all connections again, everything good. Turned on went driving 15 minutes later lost bass ckd again red...


Could be that you have a partially roasted(blown) coil on one of your subs which will function- but will keep tripping your amp.You can check that out just by using a different set of subs to listen to and by the process of elimination if the problem goes away then you know where the problem is at.Also check your gains you might be riding the gain a little high which causes distortion which causes heat(FAST) which will cause the amp to shut down completely or some amps will decrease output in a programmed attempt to save itself.turn the bass boost down to half if you even use it at all- that too can cause massive distortion in the amp itself,meaning only that if you have the bass boost on your deck turned up and then you turn the boost up on your amp the sound signal is then WAYYY distorted which will cause a thermal shutdown too. Last thing is to make sure that your subs arent running below 2 ohms because i believe that particular amp is designed to put out about 900 watts at 2 ohms.good luck

PDX 1.1000 amp overheating?


Hello thefatman69e,

The Alpine PDX-1.1000 is a physically small amp to produce the power that it does. The result is that it has less physical area for heat to dissipate. Running at or near it's maximum output into a 2 ohm load, it needs some serious airflow to keep it cooled down. I'd look for some way to get more air to it.

Hope this helps.

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.

Alpine pdx 1.000 keeps cutting out


You are going to want to make sure all your power wires and grounds are 4 gauge as well as the wire leads to and from the capacitor-4 gauge also. make sure you have a very good ground - the power wire from the battery should hit a distribution block-from the dist. block a 4 gauge should go to the capacitor another 4 gauge to the mono amp and another to the 4 channel amp -every component should have a good solid ground even if you have to bust out a grinder and a drill and some self tapping sheet metal screws and go nuts on it- see if that helps you

you need more batt, more amps, try new batt, capacitors are paperweights, spend on good batt.

Most power out of amp w/out blowing subs


you may only be able to get but so much out of the subs. If you turn the bass down a little so the that you dont drive the subs so hard you may get a little more wattage out of them
