How big of am amp do i need?

yes, but you will need a significant 12 volt power inverter to support 500 watts

If you sub is dual 4 ohm voice coil, you can get a 4000 watt amp (which will give you 1700 watts RMS at 2ohms). The model number is OW-BAMF40001D. Hope this helps.

• You double the watts to the speaker for the channels bridged. This also depends on the Ohms of the speakers being used. The lower the Ohms of the speakers used in relation to the Ohms of the amp also increases the watt output of the amp.

i think its a power acoustik amp im not sure that was a pioneer model. if it is apower acoustik the specs are

125 rms x 2 @ 4 ohms
150 rms x 2 @ 2 Ohms
300 rms x 1 @ 4 Ohms

You can only bridge the amp at 4 ohms dnt go lower than that

Assuming there is no short, or lose ground wire somewhere inside the box, diodes( in the amp) are fine, you might be overheating it by not allowing it to get good ventilation. This can be a big deal on some low end Chinese amps. Or the speakers are blown , or your Resistors (in the amp) are bad, but for arguments sake.
Most people don't use the proper size and or conductivity types of wiring, for pushing high amperage Think about it like this, Watts (power) =.Amps (energy) x Voltage (pressure) Resistance or Ohm's (amount) determines how much Wattage will go in or out, Ohms = Volts x2 / Watts.
What gauge wire are you using on your setup?

You want an amplifier that is rated for the subwoofers. In your case your subwoofers are rated at 1500 watts rms each, so you will need an amplifier of 1500 watts rms or more for one subwoofer. good luck

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.

it really depends on ur choice but if it were me id get the biggest mono block amp i could to run the sub. and id run a 2 to 4 channel amp to power the rest.that way u get ur bass on it own supply and the voices on there own supply.if u want more detailed help let me know [email protected]

first whats the range in terms of WATTS that your 12" sub can handle in 4 OHMS ? second , lets check the AMP , POWER ACOUSTIK 1800 WATTS , Now thats a lot of power to drive a single 12" sub speaker . your amp is 1800 watts , per channel is around 500 watts , if BRIDGE thats around 1600 watts rms for ONE channel , if your sub can handle that kind of wattage fine , but it will not blow the amp , what it does is shuts down , some kind of protection mode , it will come back on after a minute or so. I suggest to use one channel in stereo mode , or purchase another sub to use the other channel. i hope this helps AJ

an 8 gauge should work thats a small amp and remember that the same gauge that u put on as a power wire make sure the ground is the same gauge
