I want to hook up a pair of 100w RMS 6x9s(300w peak) to my 200x2 amp. Heres the issue the speakers are 2 ohm and the amp is 4 ohm, will any damage result in the pairing of these to components be it to the speakers or the amp itself? The amp is a old Kenwood KAC-746 and the speakers are new Infinity 3-Way 6x9s.

Features:
RMS ratings ~
35w X 4 @ 4 Ohm stereo
50w X 4 @ 2 Ohm stereo
100w X 2 @ 4 Ohm mono bridged

I think you will only be able to use 2 out of the four channels for 50 x 2 @ 2ohms. If you bridge 1-2, and 3-4 down to 2 ohms, the amp will most likly overheat, or fry.
Maybe run some more comps on it for 4 drivers total.
those 6x9s off 1 and 2 for 50 at 2, and comps off 3 and 4 at 35 each at 4

what?

The amp doesn't go down to 2 ohms I dont think. So what if I do bridge it to get the 100w per channel do u really think it will fry?

You can run 4- 2 ohm drivers
4- 4 ohm driver
2- 2 ohm drivers and 2-4 ohm drivers,
or 2 4 ohm drivers bridged.
But not 2 -2 ohm drivers bridged.

What?}

Well My owners manuel doesn't say anything about 2 ohms so I dont know where u got the info. It only shows me "X"x4 ohm setuos. Also I don't fully understand all that last bit. So when I hook these speakers up to this amp bridged what is going to happen? will they paly if I keep the gain down or will it fry right away or just shut off?

if you hook it up to the amp bridged the amp will see a 2ohm load and more then likly blow maybe not right away but it will.

according the marcs specs you can run 1 off each channel and be fine.

Heres where I got the specs.

http://www.caraudio.com/forum/showthread.php?p=1939045

And also from the Owners manual at kenwood.

http://inform2.kenwoodusa.com/manuals/kac746.pdf

In the manual, It says bridging it at less then 4 ohms will damage the amp.


I may not know it all, But I do know amp/speaker wirering..
