Free Air Sub advice

[TheSkyIsTooLow]

Hey all!! I drive a 93 GS300. It has a factory 10 inch free air sub. I desperately need to replace it. I've never dealt with free air before..but definitely sealed and ported enclosures.

The majority I see are around 150-200 watts RMS. Seems kind of low to me. Is it possible to use a sub not intended for free air use?

I'm not looking for insane bass in this car...my other car has enough(2 Kicker L5 in ported box..32Hz, Sundown Amp).

Any suggestions on free air subs, and regular subs would be appreciated.

Thanks
