Quick Question - 3 speakers w/ 4 channel amp?

[cerebus1 10+ year member]

Can I use a 4 channel Amp to run 2 6x9s and a 10" sub? Amp is 80 x 4 / 250 x 2...would bridge the sub and then run 1 6x9 on each channel....Would the sub get 250 and each 6x9 125?

Thanks

it would give the 6x9s 80 apiece and the sub 250w. it would work just fine.

This is assuming, however, that the sub in question is either a single 4 Ohm voice coil sub or a dual 2 Ohm voice coil sub that can have the coils wired in series to a 4 Ohm nominal load.

This is because the majority of amps are stable no lower than 4 Ohms in mono bridged configuration and that would be what you'd have combining 2 of those 4 channels into a 3rd, more powerful output.

Outside of that one restriction jmanpc is absolutely correct.

80w each to the ByNines being driven by the 2 channels in 4 Ohm stereo mode and 250w to the 10" being powered by the 3rd bridged output.

What do you think of the Polk Audio db104 -- Its an SVC that handles 270 RMS...I can get it for 50$ w/ free shipping...plus I plan to use the polk db series as the 6x9

Sounds like a perfect plan.
