So this is almost brand new. We installed it all for a customer under his seat and it sounded great.
When he came to pick the car up, he loved it but wanted deeper bass which no under seat sub can do so he paid extra for a bigger system in the boot.
So we removed everything and boxed it up so selling it to recover our costs.
