System on a Tight Budget

Sorry, partially my fault for getting off track here, but I was slightly annoyed.  Meef.  Is that box for 2 subs, or is the 1.25ft^3 the volume of each chamber?  If the volume of each chamber it will work, if the total box volume it is way too small for 2 shivas.  Check out the Shiva Sealed Application PDF on the adireaudio.com site for more information about the recommended box sizes.  1.25ft^3 per sub is pretty good for the shiva for car audio.  The shiva is NOT a small sealed box subwoofer.  If you need significantly smaller than 1.25ft^3 per sub you should either look at only buying 1 shiva or buying a different subwoofer.  1.25ft^3 is in the range of one of the "High Q" designs the pdf talks about.  Check it out.

meef, i think those shivas would probably work good in a vented box. find one online that matches up with the T/S specs. if the manufactuer has reccomened sizes choose the mid sized one if it will fit in your car.  once you get the box, cover the ports with chicken wire or some kind of mesh, and put what looks like a little too much, (more than 50%) pollyfill. and add more or less to your personal  tastes untill a that bass is as low and smooth as you like.

reading that made me think on a comp i was at. my shop had an 02 eclipse with a kicker solo x 18 and 2400 watts, very rough system because it was only about 1/3 of the way finished. we just wanted to test it. any way, we went up vs. an older hatchback mustang with 2 13w7's and almost twice as much power, it was close but we edged it out by almost 1 db. just thought that might be interesting.
