2 ohm amp

Hmm, well I am not too familiar with audiobahn subs, but generally you will gain a little more output from a ported box, so to maximize your volume yes.

But the key here is whether of not YOUR subs will work in a ported box, so either contact customer support or visit their website and see if there is any info. Generally they will list  the vloume requirements for the sub and whether or not it will work ported, but my guess is yes

Again, you must find out through Audiobahn about the size requirements and port sizing. More than likely your current box will be too small for a conversion to a ported box. So a new one must be built or bought.

What may I ask, are you wanting out of your current setup? More volume?

ok, the time and money put forth for a new enlosure may equate to a whole system revamp, new subs, new amp, and the proper enclosure.

I don't want to knock your gear or put you down for buying it but, audiobahn and pyle don't really perform as well as they look. Stick with what you have and save some money for some good perfroming gear in the future.

I am sure you read the post below labeled "pyle"
