Meh, i got a shit Avalanche amp from straithfield for $100. 4 x 200w (800Watt Max) powering a Pioneer 12 inch. I rip the shit out of it and its surviving. Im not too worried if it blows. Sounds very nice too.
Yeah the problem is trying to fing them. Try Just Jap. www.justjap.com.au Sent them an email.
I think im going to glue mine on so no one will rip it off.
