Audiobahn sub Q

Saw these on Ebay and was wondering what's your opinion on them.
seemed pretty good in terms of looks but does anyone know the quality on these subs

or does anyone know where else can I buy good quality subs in the box for a better price.

Also, around how much would it be for a shop to install subs and amps?

Thanks a lot

audiobahn used to be a big thing when they first came out, but they seem to have fallen out of favor of late. It looks like a bandpass box - they are REAL finicky, it might sound good in YOUR car or it might not - hard to say.

Audiobahn Is The Best BOOM For YOur Buck!! I Wouldnt Go Bandpass Though!!!
