Experience is everything with amps. I'm sometimes awed and persuaded by the technical comments on here, however music is ultimately a practical art and amps often just need to be plugged in and turned up to see if it works. In a way wattage ratings etc. are neither here nor there if the amp does (or doesn't) do the job. At the moment I'm rocking a mini-stack with a 1x15 (TE1153), and the classic TE2103x (which has 2x10s and 2x5 in the same enclosure), driven by my old GP7SMX with the gain set at 3/4 and the volume between 1/4 and 1/2 most of the time. There's loads of wisdom on here that talks about comb filtering, power rating etc., but regardless it just works for me!
