I have a kenwood 7252 2 channel amp and 2 12' kenwood 3009 subs at 4 ohms each.

the amp say that it is 500watts rms x 1 at 4ohms stable.

but my speakers are wired at 2ohms.

is this safe and if it is can someone give me the best setting for the amp i.e. hz, frequency and db settings oh ya input sensetive.

Nope, don't bridge that amp to 2 ohms, run it stereo or get a different amp or sub configuration.

it hits hard at 2 ohms is this just for temporary?  and if I go stereo is this going to be weak.

You will probably lose some volume running it stereo.

Running an amp at a lower impedance than rated will likely shorten its life and increase heat. I wouldn't recommend running it at two ohms, but it's your amp.
