    What sub to use with this amp?

    I have a Coustic Power Logic AMP 260

    It says "45 Watts RMS Per Channel or 125 Watts RMS (Bridged Mono)"

    I just want to hook up a single 10 inch sub woofer but I don't know what kind to buy, as I am 100% green when It comes to amps and subs and what goes with what. the amp is so old that there isn't even a manual online so I had to scan a page from a friends and paste it online. These are the only specs I have for it.

    Picture here:

    Any help would be awesome and a great contribution to a green horn!

    Thanks again.

    Also, I went to crutchfield and they recommended this:
    Rockford Fosgate R1S410 Prime Series 10" 4-ohm subwoofer at Crutchfield.com
    and said I could use a 4 ohm sub with a wattage of 100-150

    How did you figure it would work? Like how do you calculate it that a sub will work with it?

    That amp you have puts out 125 watts @ 4ohms bridged, the R1 is rated 150 watt RMS. It is a single voice coil 4 ohm sub. 125 watts going to sub that can handle 150 watts. No calculators, most of the guys here have been in the business a long time...
