Hi, I have a Phoenix Gold Tantrum 600.4 4ch amp.
These are the specs..
75W rms x 4 (4 ohm stereo)
150W rms x 4 (2 ohm stereo)
300W rms x 2 (4 ohm bridged)
I want to use 1+2 channels for front stage and bridge 3+4 for my sub. Is this possible (what do I need to do?), what wattage rms would i get???
Many thanks in advance! |

shouldn't be a problem. just make sure you don't put a load on the bridged channel below 4 ohms. set all settings as you would normally for a sub amp. you should get 300W to the sub and either 75 or 150W for the front channels. |

Thanks Brandon!
It says in the manual...
Minimum bridged load - 2ohms
Minimum stereo load - 1ohm
Maximum power load - 4ohms bridged or 2ohms stereo.
Does this mean I still can't run under 4ohms for the bridged 3+4 channels?? |

yes, no less then 4ohm on bridged channels, so the sub needs to be sigle 4ohm or dual 2, any thing else, not going to work correctly... |

it's clearly stated as a 2 ohm bridgable amp.
What's the brand/model? |

oh - I'm stupid 
in the manual under "common specifications" it does say -
Minimum stereo load - 1 ohm
Minimum bridged load - 2 ohms
but it doesn't give power ratings for either.
I would guess power's about the same and there wouldn't be much to gain and the amp would be stressed. |
