Can anyone give me any advise on fireing subs into an enclosure instead of out of one? I heard 3 Audiobahn 1505s reverse fireing into small boxes in a ford explorer, and it was loud. But don't know what the prosand cons of this would be.

The only difference is that you won't have to deduct from the air space taken up by the subs. But if you do a good job with the design, it could look really pimp.

you will have to wire the subs out of phase. - to + and + to -

Cause when you fire them into the box, you are reversing the phase of the speaker. Normal phase pushes a speaker forward, 180 degrees out (faceing in the box) would make the speaker fire backwards.

One more thing, if you had the speakers fireing into the box, and didn't revers the speaker wire, your sub would fire opisite direction of the rest of your speaker (eg. 6x9s, 3-1/2s and so on) and would cancel them out. In return, your components would cancel out your sub also.

Most people's 6x9's and 3 1/2"s don't play sub bass frequencies. Cancellation is not the issue. Group delay is....
