Default Amp suggestion for woofer.


I'm in need of a Class D that can do:
  • 100W into 2 Ohms
  • User set voltage gain
  • "Semi-audiophile" grade. I want to pay 50% of top of the line price to get 90% of perfomance.

I've looked at the Hypex nCore but it's overkill. Surely there must be something on eBay in kit form? I tried searching but the amount of information is just overwhelming... Looking for a "known good" configuration.

This will drive two SEAS L26RO4Y in parallell.

Many thanks!

probably an apex d200 at + - 30v will do it

OK, looking at the Hypex UcD180ST now. Does seem very reasonable!

I will go this route.
