advice needed on sq

Hey guys,

I need some advice as there seems to be some incredible knowledge and tallent on this site.

I am planning an new install into my Crossfire (hatchback), and want to build for SQ. 

I am looking for advice on whether I should use both my subs (listed below) or one, and placement options for best SQ.

I currently have 2 Rockford Fosgate Punch Power dual voice coil subs, an Alpine PDX1.1000 to run them, and Canton QS 2.160 front stage which is going to be run by an Alpine PDX 4.150

Now my question is, first, should I run 1 or two of the subs, and second, considering the size of the cabin and that its a hatchback, where should I mount the sub/s (placement) and what type of box.

Thanks guys and I look forward to your suggestions!

I would agree with the say goodbye to the good ol' Rockfords of yesteryear. In place I would look at a pair of Eclipse SW7200 12" aluminum cone subs in a nice small sealed box. Really nice low end extension, not a one note wonder and for years has been a highly proven performer in the SQ arena. They are a TC Sounds manufactured sub (score 1 for hamfist). They are also one of my favorite subs and have been for years now.

The sole reason for the two sub approach is to effectively use the power that the great little Alpine amp can produce. There are other options on the table (cough Morel Velvet Hammer cough), mind you the options will depend on your investment you wish to make. More output is usually found by rear firing the subs, to tame things down some, like Dave recommended and does practice, fire them forwards. It may well be worth your time to build a basic box and try it in each direction to see hands on what effect it has for your tastes.

Dave, TC Sounds in Canada is not in the customers best interest. The shipping, duties, lack of support, it just does not add up here in the Great White North. TC Sounds has yet to respond to multiple requests from me at the same time. How on earth are they going to respond to a individual when they cannot respond to a dealer. At least with the Eclipse route, all avenues are covered.
