hi mate, i bought one of the fli trap subs, its loud but the bass notes are crap.. jus thumpin to every tune... it wasnt the self amplified one... but the sub is exactly the same, jus didnt have the built in amp..i knw a few people who hav had trouble with the built in amp version.. so i decided to get the one without the amp.. anyway.. i hav taken the sub out and replaced it with a MTX Thunder 400watts 12" one instead, sounds pukka.. i'm actually sellin the sub n box now as i have picked up a 15" sub instead.. i'm askin for £70 for the sub and box..i will try get a pic on here 2moro.
let me knw if anyone interested in buyin it.
