Need help with deciding on amp kit

[pastieman]

Hi all

Im trying to make an amp to drive some tactile transducers for my PS3.

I'd like reccomendations on a prebuilt or kit form amp to power 2 channels at around 50W-100W at 4Ohm, sound quality is not the biggest factor as they shouldnt be making a lot of sound.

Below are some details of what I have already to work with

I have a couple of SMPS's available already and some metal enclosures.
And have already built a preamp/24db low pass filter.

I was looking at
2x100W TDA8920BTH Audio Amplifier Board class D+speaker protect BTL200W
and the like on ebay, there seem to many different types with basically the same chips.

The boards specify 8A maximum current, the SMPS I have is rated for 6A at 24V, I'd normally be comfortable just keeping it turned down but I hear class D amps can have trouble with not enough current.

The other option I was looking at would be a 200W vellemen kit, although that requires a split supply so I would need to use a virtual earth on the SMPS.

Any reccomendations/suggestions would be welcomed for boards/kits that I could use with the 24V-40V SMPS (6A@24V)

Also looking at
sure electronics 2*100w TK2050 TP2050 Tripath Class-T AMP

Although these seem to have huge current requirements.
