Will this fit the bill? Should I go with a different brand?

Its 60 watts rms, which the speakers are 56, should I go higher, or this would be the safe limit?

Colonel Sanders makes 6x8's ?!?!?!

//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif just kiddin'. 60 would be fine, if you like that amp go for it. The speakers could probably handle a bit more with proper x-over settings though //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Can you explain x-over settings?

Heh easier said than done. Basically those 6x8's can take.... say the full 56w from 20hz-20khz (the scientific range of human hearing). At 66w, the woofer could start to bottom out on low frequencies and you'd hear distortion, to fix that you set the x-over so that the 6x8 only reproduces say, 40hz-20khz. At 76w this could happen again, so you set the x-over to 55hz-20khz. Eventually you can't do this anymore as you reach the thermal limits of the driver and the coil burns up due to excess heat.

All of my numbers (except 20hz-20khz) were made up, just an example.....hope that made some sense to you? //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

If you want to know more about what a x-over really does I suggest you search google, there are a few sites that explain a lot //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
