first,

the amp I have. crystal CAD600.2t

next,

Avionixx_AXT_1200.2

Link here. http://ampguts.realmofexcursion.com/Avionixx_AXT_1200.2/

thses two look exactly the same. but have diff power rating. why?

 
oh. lol. soryy.

i have been looking and many places, including people on here, say the Avionixx_AXT_1200.2 is rated 1200x1 @4.

where as the crystal is rated at 700. that is a big diff.

 
it would just be awesome i i could get more than 700 @4.

when i bought the amp i thought i could run it at 2 ohms.

but my subs a d2 and im a ****in noob.(yes i admit, i have ALOT to learn)

 
as notes, it is often hard to determine exactly how much difference there is in electronics just by looking at something. Think about how people can optimize car engines with visually minor tweaks. maybe not double HP or anything, but enough to be useful. For electronics, this can be similar in that often boards are made to support many options.

For amplifiers, component ratings may be optimized. It may be the case that more expensive, lower ESR caps are used instead of cheaper parts for the power supply. Maybe the MOSFETs have been chosen to be more optimal for the application. there are a variety of tweaks that might be done to improve a spec, or tune it more for a given application.

for example, the top amp has extra poly caps -- the reddish square/blobs that are next to the big tripath IC. The main transformer (ring with wires wrapped around it, laying down) may have been wound differently. the rest of the output filter may be different as well.

that said, I'd be more inclined to think the amps are likely very similar.
