Eligh Unregistered guest | I have a 2 channel amp that puts out 550W RMS when It is bridged to mono at 4ohms. I have it hooked up to two 12 inch 8ohm DVC subs. Now, is this configuration Ok and how should subs/amp be wired ? |

Eligh Unregistered guest | I think they are 4 per voice coil. |

Eligh Unregistered guest | Glass won't each sub get the full 550 watts? If not is there a way to do that? |

Sometimes it's better to just leave things as simple as possible. |
