12" DB Audio T-Rex sub, 600wrms, not in show quality as it had to be repaired (bear in mind it is about 5 years old) but sounds just as good as before.
Dual width ported sub box tuned to 30Htz, in grey
Pioneer GM5300T 2 Channel amp, 760w max when bridged to mono, chose this so i could run the sub at the rms all day long it had a bit of a mishap in the boot of the breadvan though where it was basically sliding about on some screws for a few days and as such is scratched to buggery, but works fine.
cost a bomb new and still all sound just as good, what would you lot wanna pay?
Oh and i'm sure those who have heard it will vouch that its not for the feint hearted
