I have two of the 2004 model MD2D amps and was wondering if they were strappable or if it was a god idea to do so? I'm planning on running them on two Orion H2 15's with dual 4 ohm coils. Would i be safer to just run each amp to a single sub?

No it is not and even then you have either a 4 ohm or 1 ohm load neither of which will give you as much power as running a single woofer @ 2 ohms per amp.

Thanks for the info. That's what i was thinking but I wanted to make sure first. I've had an MD2D for 4 years now and love it. I've never had any problems out of it at all. Great Amp!
