Shaun, thanks for the advice, however 1) just tried the website and it still says "sold out" next to the quantity box, and 2) after a great deal more reading and research I decided to go all-in-one and take your advice and just order an ASP from RCTA. By the way, Kevin from RCTA is in the US for the next few weeks, and thus is saying he'll only ship to US customers for that period. So on the plus side for us here in the US, we can get stuff from him a lot faster as he's shipping from Tampa.

I have another question: does anyone have a Heng Long or similar Sherman that they have mounted more than one speaker in, or a single larger than stock speaker, and if so do you have any photos you can post showing how you organized it to fit?
