is there a way to lower RMS ratting of an amp

[Odelay]

I friend gave me a Kenwood amp that has a RMS rating of 60 Watt RMS x2 at 4 Ohms, the speakers in my doors are only 40 watt RMS. The speakers have built in cross overs which should drop the power a bit, but not 20 watts. Would dropping the gain be okay or is this amp just going to blow my speakers? I currently have a 4 channel amp in my trunk with 2 channels running 6x9's at 50 watts RMS. with the other 2 channels briddged to a 10" sub running at 150 Watts. I guess I could run the 50 watt channels to my doors? would that work?

Right now the 4x6's are running off of the head unit and I have to have the volume turned tot he front at about a 10 setting out of 16 to get a balance of audio. I am thinking about putting in some 5.25"s in the front doors, but none I can afford run of 60w or more, they are all 40 and less.

Any ideas? Thanks for reading!

Here is the AMP : Kenwood KAC-5204

Here are the speakers I was wanting to run on it: : Polk Audio db461

Just keep the gain down.

set your gain correctly using a dmm

tl:dr it all. But from what i did grasp your speakers should be fine on the power as long as your gains are set correctly

I doubt that Kenwood even putting out 60 RMS anyway... but like was said just set your gains correctly...

why would you groan some one trying to learn how to do it right instead of just cranking his amp all the way up and frying everything?

Wow, thanks for all the replies, I appreciate it! Will going by ear be okay and just listen for distortion? only equipment I have is a volt meter. :/

dmm is like $10 at walmart, hell probably cheaper.

Ok cool, thank you! I am sure there are threads describing this, google here I come!

Thanks again for all the help!

Yea, kenwood aint really known for putting out their rated power so you should be fine. I got my DMM for $20 at radioshack.

Sounds like you've got a very mix/match setup going on haha. Where abouts in SoCal are ya?

I was thinking the same thing... I was so torn between groaning for the title and grammar... or letting it slide for the eagerness to learn.

Odds are if you set the high pass crossover at around or a little over 100hz the speakers will handle it OK as long as you don't clip the amp to hard.
