I have a custom made 350z sub box fits in the aperture of original Bose sub. Fitted with a Rockford Fosgate sub if interested. I'm currently running Focal Speakers .
The car cruises in and around Oxford street in London support these in a big way, however i did see video once of a guys rear bumper caught fire, totally unaware until the guy following bought it to his attention.
How crafty, the amount of different cars available for the police to use nowadays are unbelievable. Gone are the days of the old jam sandwich. I've seen them in a Lamborghini once, how nice to get that privilege to smoke round in that all day .
I agree with Pete, should you not mind purchasing a cat C or even entertaining a cat D, its unlikely to find one at sub10k. There's nothing wrong with these catagories as cars are more likely to be written off these days due to manufacturers retail part prices. Cat D obviously being a better option and the Cat C requiring a Vic test due to a heavy impact.
Yes my lad had the passenger front problem when he got the car. He just lived with it until he had his new head unit and speaker install. Have you an old speaker you can wire up, then if still persists then go to the back of the head unit.
The r35 wont be a straight fit buddy it needs chopping shorter in width, with new bends formed, followed by a tip of your choice. The r35 is a lot wider car than the Z. My son had his fitted earlier this year, the sound is awesome.
