Hi there.
I'm a newbie and would just like to clarify something in my mind.
I have 2 sets of Polk DX3065 (Problem with living in a 3rd world country) splits that I would like to drive with an Audison LRX 4.300 amplifier. Now the amplifier's rating at 4Ohm is 65W x 4, and at 2Ohm it's 105W x 4. Now as far as I understand things if I just hook up the splits seperately on a channel I'll get 65W x 4 pushed to my splits. Now is there a way of wiring up the splits to get to the 105W 2Ohm output? Or will I need to re-evaluate my choice in amplifier?

Thanks in advance.

Sorry forgot to add that I'd like to still have each set of splits on a seperate channel. ie. Front left/right & Rear left/right.

Hope you guys can help.

You have to take both 4-Ohm speakers and wire them in Parallel to obtain the 2-Ohm load.

Wire the positive from the AMP to one speaker, then run another wire from that positive to the other speaker's Positive, and do the same with the Negative's. That is how you wire in Parellel.

Thing is the splits have a passive crossover (forgot to mention) so it would be impossable to drop to 2Ohm while using the passive crossovers?

Thanks to the reply.

You should wire the Cross-over +/- wires directly to the +/- terminals of the Amp. Then, out of the cross-over to the speakers as described + to + in a line, then - to -. This is still a 2ohm load to the amp. If the cross-over has ANY impedance, this may mess you up, but usually a passive should not add any. . .

I was hoping something like that would work... Thanks a stack for the help.
