What kind of power are you planning to send to your sub? And, are you wanting more than 1 sub in the vehicle?
I own a f-body(97) and have Stereo Integrity 307 components in custom kicks with Peerless 6.5" midbass drivers and a single Stereo Integrity Magnum D2 in the back. You can see pics either on my webshots page or on Stereo Integrity's website under demo cars. There is a peak in a f-body at appox. 45hz. If you have an EQ, it's no big deal...comes right out. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif A single D2 in the hatch of mine is more than enough for SQ. And, it will get loud. Now, there is also a guy I know running 3 D2's in a 95 Firebird. He's in the mid-140's with about 600 watts or maybe just hair more on each of them. You can get the Mags right now or by July 16 for $200 shipped in the continental US. Definitely worth checking out if you're interested. Best mix of SQ/SPL I've ever heard. Ask Loyd if they get loud
And, for rear fill....definitely wouldn't advise you to do that. You want to build that front stage as best as you can get it, and let the sub(s) take care of any "rear activity" //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
