Re: Someone help me get a clue
If you want any kind of low end response at all I would lose one of the subs and use one in a ported enclosure tuned to 32Hz. In reality, you'd be better off with a 10 but since you already have the subs, one of them at 2Ω will sound a lot better than two of them crammed into a tiny amount of air space.
Also, your Kicker amp will be happy at 2Ω, so that's a better match between sub and amp that will allow you to get all you can from the amplifier and woofer.
In the end, cone area is not king... proper enclosure design is. And you can expect to pay $175.00 to $250.00 for a properly designed and built ported wedge box.
