Bridging headinit channels front and rear

[kx250frider617]

Do you all think it's possible to bridge the front and rear head unit speaker outputs to two speakers. This isn't for a boat, I'm trying to build a small portable radio for the desert and don't want to use an extra amp. It would be a Clarion head unit powering two 7 inch Alpine marine speakers with a battery supply. 

 

My idea is running the front left and right channels to one speaker and tears to another. This would solely be to get a tad more power to the speakers. Reason I'm asking, I already have the equipment and really don't want to buy anything else

No can't bridge car stereos (there are some exceptions but they are rare, and usually to use rear channels to power a sub).

HUs normally use a push/pull BTL output chip that is essentially already bridged in order to maximize output power from a limited 12V supply. So bridging is not possible.

There are flush-mount home speakers (and some exterior versions) that have dual inputs, with twin tweeters, and a DVC midbass. This would allow you to use all four HU channels on two speakers. Or, find two more of the Alpine speakers.

I forgot about ohms law too when bridging. Oh well. The head unit should provide plenty of power for what I'm looking for hopefully.
