i finally bought a GT3 backbox and got it fitted a while ago, but didnt have time posting it here but here it is:
note that this pic was take on trick or treat night, hence the big box of sweets. lol
It's not loud at all, infact sitting in the car it's hardly noticable. but it has a nice deep tone to it, which'll do me just fine.
i will try to record the sound when i get time.
