Thanks guys. I have spoken to Fhrx and am going a small box but high powered 10" in that hole on the shelf in the boot. The amp will also be able to run two of the internal speakers and they will have sound deadening put behind them. I'm going for a new deck but will leave the rest of the interior till the next time I want to waste some money in this direction.
This is a bloody addiction. I only just bought the car and I'm lining up this stereo upgrade, new zorst and bilsteins to go in over the next month.
Am I crazy?
