I have already bought an amp. It's a Lighting Audio 200 x 2/300 X 1 @ 4 Ohms. I've planned on getting 2 stage 1 Rockford Fosgate 8 ohm 10's in a sealed box. I'm choosing the 8 ohms so I can bridge them without stressing the amp. Now I didn't really think of it till recently. Really only after I ran the wires for the amp. I plan to put it in the small storage hole on the drivers side in the back. After I remove the Factory sub there should be plenty of room. Then after I though of it I wondered if I got 1 12" in a stealth box would it sound better, the same, or worse than the 2 Rockford 10's. I mean I can get 1 awesome 12 for the price of the 2 Rockfords. The box will probably cost about the same either way. I just want the best setup for my money. If I had to choose right now I'd go with the tens, but I've got about a week. I've also toyed with 2 12's in a sealed box. It would only be about 30 dollars more than the 10's. In you guy's opinion what would you do? I'm going to upgrade my door a pillar speakers as well with some Pioneers. Right now I'm looking at 255.80 for the 2 pair of Pioneers and the RF 10's. Plus 160 or so for the box which I'm going to buy locally. So that's about $415. Like I said I can get the 12's for like 30 bucks more. I just don't want to be disappointed after I'm all done. Another thing, What size door and pillar speakers go in my car? Sounddomain.com says 7" but Crutchfield says 6 3/4. I would like to use the factory black plastic adapter if I could. I have the 5 speaker factory Bose system. Thanks for the help.

 

For starters lets get our terminology right. You don't bridge subwoofers together. You connect them in series, parallel or series/parallel. Bridging is an amplfier function.

Two 10" subs will be lounder than a single 12". The two 10's have more cone area so they can move more air. And with the limited amount of air space in a Stealthbox type enclosure you'll probably get a better match between the 10's and the enclosure than you will with a 12" and the enclosure.

The woofers in an F-Body are all 6-3/4" These are also called oversized 6-1/2" speakers. Since you have the Bose system you might want to double check that. Bose uses some oddball size speakers sometimes. Don't use the factory plastic baffle to mount the speakers if you can avoid it. Take a look at my car's setup to see the replacement baffles I made. They are a much better option than the flimsy *** factory baffles.

 

the lightning audio amp is not 2 ohm stable FYI..i would atleast go with a p2 10 or 12" in a stealth box with a fosgate 300.1 amp
