If you haven't got one yet and are still after one i might sell mine after the car was written off on the weekend.
Amp is fine, about the only thing 4 Channel large sucker, JBC. Inbuilt crossover etc was for a pair of 7X10's and a 12" sub.
It's only 3 months old, retailed for $585 from Strathfield. Sell for no less than $320. If you can wait a week or two till i know what i'm doing financially thats better. Send me an email.
