    Strapping Amps + Sub Wiring Question

    I have two kenwood excelon X1R mono-block amps. They are rated at 1200w rms at 2ohms and 600w rms at 4ohms. I am having difficulty finding a 2ohm woofer that is able to run at 1200w rms. However, both the Alpine X-series and MTX 9500 are rated at 1000w rms and 3000 peak. My problem is, the Alpine X-Series and MTX 9500's only come in a 4 ohm woofer. How would I be able to wire my amps in order to power 2 4ohm woofers as 2 2ohm woofers?

    My initial thought would be to run each amp in a parallel circuit. One amp being attached to one voice coil and the other amp being attached to the other voice coil.

    I am open to any and all suggestions. I have been working on figuring this out for days. Any help would be appreciated.

    Thank you for the diagram! That helps explain a ton. Do you know how to wire strapped amps running in parallel? I have a kenwood excelon owners manual that tells me how to strap them but I am not sure how to strap them and run them in parallel?

    What do you think about running these amps strapped to a pair of 12" 9500 series mtx woofers?

    Strapping is kind of like bridging two channels. Not all amps can do this though. You basically go + on one amp and - on the other amp. So, all your +'s go to first amp + and all your -'s go to second amp -. I'd seek some help from the manufacturer if possible though. Power ratings may change when strapped.

    Sorry, I didn't notice that you said you had 2 amps. To simplify the setup, you could wire each sub and amp separately.

    This diagram shows a 2 channel amp, but you could treat each channel as a different amp:

    Kinda like having two of these setups:

    I hope that helps. If you still want to strap the amps, I would follow HyperZulu's advice and talk to the manufacturer.
