    First you need to know if the wattage your speekers is Peak wattage or RMS wattage. Peak wattage is defined as the maximum wattage your speaker can handle, where RMS (ROOT MEENS SQUARE) is the wattage your speakers push 100% of the time. Example: Your sub may hit at1500 watts sometime, but every time it hits it pushes 700 watts, so the sub would have a rating of 700 watts RMS and 1500 watts peak. As far as your original question goes, you need to include the wattage of the sub woofer, and how many other speakers you are wiring, not just the wattage, if you have 4 speakers then each speaker is running an estemate of 450 watts, so alittle more clarification is needed.

The red triangular light on my 1800 watt kenwood amp is flashing and i do not know what to do to fix it. no sound is coming out of my subs

i have a smaller kenwood amp but it has the same triangle, i had that problem too, so i ran a ground wire from the battery to the amp, with 12 ga wire, and then i also grounded it with the chassis ground, on the big amps its better to have really good grounds and connections

Do you have enough amp to power the subs, sounds like the coils are heating up and shutting down. Twice the amp for the wattage of the speaker as in 100watt sub 200 watt amp supply and so on.. 1000 watt sub would need at least 1500 watt continuous out put

Its hard to tell what you can or cant do without knowing exactly which kenwood amp you are using. Generally speaking though most kenwood amps are stable only down to 2 ohms. you will be better off just using 2 of your 12s wired in parallel- that will give you a 2 ohm load. There is a way to use all 3 simply by wiring them in series, it will end up giving you a 12 ohm load on the amp though which will work fine but you wont ever achieve the full power that the amp can do.

What size speaker wire do i use with the mofo 15 from the sub to the box then the box to the amp

The size of the wire has more to do with the amp's output than it does with the speakers. The wire should be the same size throughout, from speaker to box, box to amp. A minimum of 16 guage multi-strand wire. Most amps that put out up to 500 watts max or have an RMS rating in the 300 watt range should do fine with this. If you want to be on the safe side, there is no limit to how big your speaker wire can be, only how small or a minimum. If you're using a very high output amp, like over 500 watts RMS, you can use 12 ga. wire. If you want to be on target for your size, I need to know what amp you have and how many speakers you have.
