Crikey, I remember that model with its styling and it competed well against Sony / Pioneer etc at the time. It states from 4ohm - 16ohm support and is rated at 45wpc with 8ohm so it has a decent quality transformer and why its moderate weight at 8kg.
Yeah its likely to hit @90 watts per channel with a 4ohm resistance. You don't want however an amp running at near max capacity constantly. As mentioned tactile with continuous low-end frequencies puts quite a bit of strain on the amps.
So yes, it could power 2x Reckhorn or ADX type units sufficiently but not really perhaps the BK Mini piston models. Be sure if sourcing a Reckhorn model to get the (i) improved version.
For example,
Here
It would be interesting to compare it with the ADX
Here on your 8020 frame and installation. Although I am not convinced the ADX, while it may be a bit better is worth almost 2x the price we have to pay here in Europe/UK to get it.
Its your decision to consider buying one each and comparing or just doing whatever you want.
Clarke TST models (TST 239 Silver) are also quite good (may need to import) from
Here
These are really excellent for engine RPM with their finer detailing but they do make more audible noise like a speaker as well.
I introduced to several people to add a TST into pedals or Seat to keep engine effects separated from the front or rear pairs. Doing this in a tactile configuration will help improve the detailing you get with the bumps as it greatly removes the workload on a single unit to have to output tactile for constant engine and bump effects etc.
Do keep in mind this old amp you have may be ideal to run units for this purpose or if your the creative type. Even powering a nice 10-12" sub placed under the seat and incorporated into the build. Audible bass energy can work really well with tactile, as both heighten the sensation due to our ears hearing the bass but or bodies feel the vibrations.
I experimented a lot with this on/off several years ago and will incorporate subs into my own build but some people will perhaps use headphones only with sims and may not want loud audible bass in a room.

Here as it gives a perspective of someone entering into tactile for the first time, even with using just audio with consoles.
