New member Username: TrojanmanmsPost Number: 7 Registered: Dec-04 | I have a 500W RMS MM12 polk audio sub. I am looking into buying an amp. Pretty set on the Sony Xplod http://www.goodguys.com/adtemplate.asp?invky=395876 it gives off 500W power bridged. I have a headunit that has a preamp out. Does that do me any good? or do i need to buy a new headunit to make it work? |

If you live in a cold climate, use it as a heater for your trunk! One more thing, don't get fooled by Sony's marketing scam. They might've been the first to use peak power instead of rms. If you're lucky, you'll get half of the stated "useable" power. |

New member Username: TrojanmanmsPost Number: 8 Registered: Dec-04 | thanks guys, but that still doesnt really answer my question about the headunit and wiring. does having a preamp out do anything for me? or do i need a new head unit? |

New member Username: TrojanmanmsPost Number: 9 Registered: Dec-04 | you guys both recommended amps that delivered 250W at 4 Ohms. My sub is 500W RMS at 4 ohms. Do you really think that these amps will deliver enough power? |

Silver Member Username: CarguyPost Number: 915 Registered: Nov-04 | Is your sub 4ohms DVC or 2ohms DVC? |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 6688 Registered: Dec-03 | you need to specify the coil configuration of your speakers when asking for suggestions on an amp. that affects the amount of power the amp will deliver. |
|
New member Username: TrojanmanmsPost Number: 10 Registered: Dec-04 | i think you mean dual voice coil by DVC. Right? Well, my sub i believe is single voice coil at 4 Ohms. In that case, will the 250W amps you and issac suggested work? |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 6707 Registered: Dec-03 | if you have a single 4 ohm coil sub, you'll need an amp that supplies: 500wRMS x 1 @ 4 ohms mono or 500wRMS x 1 @ 4 ohms bridged (2 channel) it'll be cheaper to find a 2 channel amp rated for bridged power. it'll be around 125wRMS x 2 @ 4 ohms |
