Last Saturday I was able to get the new Boss Audio BASS600 8" powered subwoofer installed.
Once again, here's the link >
Amazon.com: Boss Audio BASS600 8-Inch Low-Profile Amplified Subwoofer (Single): Car Electronics
For $89.99, I figured it was worth a try. The previous owners of my 4Runner had an amp installed under the front driver's seat, and were running a 12" sub in the cargo area. When I bought the 4Runner, they kept the amp and the sub, but left the wiring in place which made for a extremely easy install. The wiring that was there was 8GA, with some decent RCA's and a remote wire. 8GA is exactly what the install instructions called for, so I was good to go.
As long as I've owned this truck, I've wished it had a little more low end sound. I'm not sure if the door speakers are aftermarket (I'll have to look someday), but they put out very little in the way of bass. I wasn't looking to rattle the windows, just to add some extra kick to the music.
First I pulled the front driver's seat and did a test fit of the BOSS sub, to ensure that it would clear the seat and leave ample room for me to re-install my WeatherTech floor liners. It fit perfectly on both counts, so I went ahead and wired it up.
I secured it using the little rubber feet that come w/the sub. I drilled 3 holes in the floor pan and used self tapping metal screws to secure the rubber feet to the floor. I plan to put touch up paint and some silicone sealant on the screw points where they exit the floor pan underneath.
That's really all there is to the install, so I put the seat back in and took a couple pictures of how it fits.

And the same shot, with the seat moved back to my regular sitting position.
And looking underneath, with the seat in its normal position...
From the front...
And the side...
There is only one point where the clearance gets pretty tight, which is the area @ the upper RH corner of the sub in this pic...
A close up of the area where it's a tight fit... None of the parts in this picture are moving parts, so the clearance is a non issue. IMO, it's a perfect fit for this spot.
Finally, a shot of the adjustment controls.
Overall impressions: Out of the box, the sub definitely needs a little fine tuning. It comes with a Remote Level Control knob, but my deck has a built in control for subwoofer level, so I didn't use the BOSS level controller.
After I got it tuned, I ran it through some tests with some Rock, Reggae, Metal, and Rap.... all different kinds of bass notes. It performed much better than I expected, and being right underneath the seat, the output is really noticeable.
I currently have the gain set @ 30%, subsonic filter @ 50Hz, Bass boost @ about 4dB, low pass filter set @ 150Hz, and the phase shift set to 0 degrees. With the sub level control @ zero on the deck, no boost, no reduction, it has plenty of output.
So far, I'd definitely recommend, but I think some longer term testing is needed before I can say it's a "Must have".
