Sub for Sunfire

Hello, I'm the newbee. My wife has a 2002 Sunfire coup. I am trying to find a good sub to put in it with good SQ, but if she wants to turn it up she can. My range is no more than $150. I do not want to get an Infinity Kappa Perfect because I have one in my truck and I want her to have something different. This is the box I am thinking about getting http://www.woofersetc.com/index.cfm?fuseaction=product.display&Product_ID=3640 Thanks

Boston Acoustics G1 10 or G2 10

http://www.woofersetc.com/index.cfm?fuseaction=product.display&Product_ID=3640 This is the box I am thinking about getting, once I get the deminsions to see if it fits, I think I will get the BA g21044 sub. Does anybody else have any suggestions on boxes for this? I am trying to keep as much space as possible.

I'd suggest not to buy that box...Do you know what the port tuning freq. is? I'd say build yourself a custom box to the specs of the driver. You'll be much happier.

If you really want SQ build a sealed box to spec. As a bonus it'll save that precious Sunfire trunk space.
