Athena ASP repair

Hi All,

I have a couple of Athena ASP 4000 Subs, one of which has just died, I'm looking at options to get back up and running as the woofer and box is still in mint condition, that and a replacement sub would set me back more than i'm willing to spend at them moment.

Essentially the options i'm looking at are to order another plate amplifier such as this one

Or looking to order a amplifier that has the capacity to power it as a passive sub with enough head room to do the second if it should ever fail.

I did consider car amps and smaller units from amazon like the Fosi audio amps however the power supply required becomes a bit of a pain with extra unnecessary work.

The subwoofer pre out from the Yamaha amp is 1V/1.2 k-ohms, crossover is set in the amp.

Would either of the above work, has anyone got any other suggestions?

Thanks all for the input
