I just wired up a C70 amp to the SC-901. You can buy the C70 amps on ebay if you don't have access to junkyards. I just did custom wiring for this project. There is a thread (see below) on how to do it. It isn't the most clear write-up IMO so let me know if you need any help and I'll do a more thorough write-up job and post it.

I went with the C70 amp route, seems like a better amp + it's the only one I could find !
As soon as I receive it I'd love to use your future writeup :D

Do you think I could power the amp with the wiring for the heated seats as I do not have them installed on my car ?

Boy was this easy !
I'm almost done, took some pics along the way, does anybody know where I could find a solid 12v point outside of the motor bay ?
I'll do a write-up this evening !

Check the fuse box for spare sockets.

But that's inside the engine bay ?
I'm trying to find a place to attach the 2 power wires to the amp.

But I found the gromet next to the pedals and I managed to get the wires through there and to the battery's positive terminal.
