Hi,

I am putting 4 of these speakers http://www.rocktheboataudio.com/html/52530.html and one of these subwoofers http://www.rocktheboataudio.com/html/53109.html into this ice chest http://www.academy.com/webapp/wcs/st...222-01260-2628 and I plan to power it with one of these http://www.homedepot.com/h_d1/N-5yc1...&storeId=10051. Sorry about all the links, I don't know how to implant them into regular text.

Anyways a few years ago I made a stereo in an ice chest using some old 6x9s and a Head Unit from my car, and I powered it with a lawnmower battery. But, the ice chest was too small and the casing I had the stereo in got wet and it died. So now I want to use a bigger ice chest, mount the speakers at the top of the sides instead of on top of the lid, and not use a head unit. My understanding is that I will have an mp3 player > amp (via 3.5mm to RCA cable) > speakers. Is this correct, and with these speakers what amp should I get?

The speakers each have 4 ohms, and a 20 RMS limit, the subwoofer has 4 ohms and a 50-200 RMS limit. I have never used an amp before so are there any suggestions as to what brand and kind I should use? Please keep in mind that I want to mount it preferably inside the ice chest and the depth of the speakers is already taking up some volume. Thanks.
