my alpine amp was working great one day and out of nowhere while is was knocking one 12 inch JL W6V2, tha amp cut at high bass. now there are two lights on both sides of the control panel to control gain and such, the light on the right is RED, and the light on the left is blue, it will turn on but will not send power to the sub, any ideas? i din't think that one 12" W6V2 was too much for that amp? if anything the amp should've been too much for the sub.

Re: ALPINE PDX 1.1000
Well you would have to look into the ohms of the amp compared to the ohms of the speaker. If the ohms are different you would have to hook them up in a different way. check the RMS on the speaker as well as the amp, this can also be sufficed by wiring it different if ohms match up properly! Hope this helps you out and if this is not the case let me know.

Cut your gain back on the amp. It sounds like they are set too high. Check your install instructions on how to set your gain. If you have a 4 or 5 volt output head unit your will not be at half way. Im running a JL Audio 500 /1 on a skar wwv10 dvc in a ported box. My gain is set about half way & its plenty loud.I have a Alpine 9887 headunit 5 volt output on my RCAsI can take a volt meter & set my speaker output at 45amps & my gain in perfect.
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.
Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.
its not the amps my dude ur ohm loading is wrong if u have a 4 ohm stabled amp n ur speakers r 2 ohms naw thats not gonna fly caus it cant put out what ur asking 4 so u need 2 reload ur subs try this link http://www.bcae1.com/spkrmlti.htm this should help u out n save u money
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
Power source voltage is too high (aka above 14.5V).
The easiest thing to do is to try removing the connections to the speakers at the amp and see if the issue disappears after each set has been disconnected. Keep removing wires until both LEDs stay blue.
You may have a problem with the power source feeding the amp. You need to check the voltage across the amplifier's B+ and ground terminals when the amp is playing/cutting off. If it's dropping below ~11 volts, you need to determine why it's dropping so low.
