you deffinatly need to give us more info. what is the model number? how do you plan on running it. I am a pioneer fanatic but i have to say most pioneer stuff is mediocre at best unless you actually spend the time/money to get there higher end products. IE Premier.
I want to use it on a Pioneer Deck - DEH-P2550
and i currently have an INFINITY Amplifier 2 chanel about 400 watts and two pioneer 6x9 speakers 340watts each.
keep in mind audio selection in AU is limited, and prices are a lot higher thanks to import taxation and general price padding.
Computer hardware is just as bad.. usually twice the cost as it is here in the US
