So I have a Pioneer TS-SW841D 8" sub...original plans were to replace the stock sub in my 12' IS-F and place it in the deck where the OEM sub is.
BUT, I'm reading mixed reviews on the sound quality of mounting this free air versus in a boxed enclosure.

Would the bass be ok mounting this in the deck where the OEM sub is or should I put this in it's own box/enclosure? Any amp recommendations? I don't need to rattle the windows of nearby buildings but I would like a little deep, low bass.

Specs:
8" Single 4 Ohm Pioneer Subwoofer
Power Handling:
Peak: 500 watts
RMS: 120 watts
Impedance: Single 4 ohm
IMPP Composite cone woofer
3-Layer fiber woven radial surround
4-Layer, long voice coil
Frequency response: 30-1500 Hz
Sensitivity: 85 dB

I may be wrong, but believe the stock subwoofer is free air. Free air or infinite baffle will not give you the loudness and punch you get from a enclosed or ported box. Google the differences between the 3 main types of baffles (infinite, ported, and sealed). There are more, these are the 3 main types.
That being stated, I doubt the aftermarket Pioneer will fit in the OEM speaker location. I tried on my 2010 LS 460. I ended up adding an amp and a ported subwoofer. I installed a 150 W RMS mono amp with a 10" subwoofer. I tapped into the OEM subwoofer wire ps with a line out convertor. Now I get plenty of bass. Some might think too much.
Do a search for subwoofer replacement and you'll find a few threads.
Good luck.

I have heard good reviews on that particular subwoofer, but I rather not mess with the rear deck... instead look into this box: http://www.audiointegrations.net/lexus.html

If your desiring anything but modest bass....free air isn't for you....free air=more wattage to create less sound.....and more heat on the voicecoil....which is why if you push the stock sub to much they'll blow out....
