i see a hole. apparently it's an 8 inch hole. mine has a metal plate in it. no speaker is present.
i have a little amp. i had the guys that installed the stereo run an "amp kit" into the trunk, consisting of two ridiculously huge power wires and a wire to turn the amp on and off with the stereo and/or key.
now, methinks i might put an 8 inch speaker in FROM THE BOTTOM - without removing the rear window tray, etc...
It isnt hard to find an 8 inch subwoofer at all. Rockford and JL both make 8 inch subwoofers. I'm sure the vast majority of manufacturers have 8 inch models. I prefer Rockford, they hit hard, are fairly clear and are relatively inexpensive.
You also could build a box that mounts around the subwoofer, it would be tedious but it would help the subwoofer get the best clarity. I've seen it done before and its really inexpensive.
You could simply buy an 8 inch subwoofer and put it in there, but it wouldn't sound the greatest.... barely better than stock.
As for 8 inch free air subwoofers, they aren't hard to find either. Many marine subwoofers are free air woofers, all you have to do is take off the plastic guards. Lots of low end subwoofers are free air also because they are designed just for this purpose. Many companies advertise them as component subwoofers because they are meant to replace OEM parts and only handle around 50 watts.
It can be dropped right in place of 7 speaker Avalon's woofer or used to expand the 6 speaker Avalons. Just make sure your "little amp" doesn't put out too much power for a comp subwoofer.
I haven't literally been in there because my head doesn't fit. I've never seen a 6 speaker or 4 speaker Avalon so I don't know if you need to cut a hole or not.
Outdoor speakers might not have the clarity you need. There is a lot of leeway with outdoor speakers because of all the background noise in outdoor applications.
I have the 6 speaker avalon, there is a 8 inch hole that is easily knocked out if the oem sub is not present. However a problem exists, you cannot put a subwoofer in withoutcutting into the carpet, or installing a spacing ring. Otherwise, the foam surround would be resting and pounding into the carpet material, sounding like garbage.
Another key issue, is, for optimal sound you will need to use a baffle that would idealy cover the whole underside of the rear deck. Using this idea and the former, if you were to cut- say a peice of MDF 15 inches by 36 inches or so, and cut a hole to stick the sub woofer in, this provides you with your spacing and baffle board. the only tricky part will be creating a baffle board that fits around all the oddly placed crap in the trunk.
And because it is a small subwoofer and mentioned a small amplifier, be sure to pick a subwoofer with good watt/db sensitivity measurements. Like 88db+

Well you obviously would need to cut a hole in the carpeting because you'd hear a rattling from the plastic hitting the carpeting. As for optimal sound, a free air subwoofer is designed specifically for applications like this. They are supposed to be mounted on the back decks of cars without dedicated boxes. If you really feel the need to make a box out of MDF every good manufacturer has "ideal" specification for boxes. For instance the Rockford 8 inch Punch subwoofers are designed to be mounted in boxes that are from .5 cubic feet to .75 cubic feet with an ideal box of 12x18.5x8. Just check the manufacturer's website, they have tested these subs over and over again and know what is best for them.
It's 4 ohms. At least mine is. I doubt the woman before me replaced it. If Toyota's numbers are right she was probably 65 and had no reason to replace the factory subwoofer. You want to get the Kicker C84.
The stock amp will power it. But I am not sure if the 4 speaker, 6 speaker and 7 speaker amps are different. You should look into it before buying and installing. Also, you can find a better price elsewhere. Though Crutchfield offers buy one get one free, they also mark the one up 175 percent. Just go to google and type in Kicker 10C84 in and click shopping, you'll get plenty of good deals.
The link didn't connect. But if the amp puts out 20 watts and your speaker has an RMS of 100 then youre in the clear. RMS stands for Root Mean Squared. There is a ton of mathematical mumbo jumbo I can say about it but basically RMS is the maximum CONSTANT your speaker can handle. Your amp may be rated at 20 watts but it can have spikes of 30 to 40 watts. Thats no problem because your sub can easily handle a constant nearly 3 times that amount. RMS is almost always half of the maximum power handling capabilities. So long as your amp rating isn't much higher than your sub rating than you're fine...
In layman's terms... yes, the Kicker 10C84 will definitely be able to handle the stock Avalon amplifier. It'll be like towing a boat with a semi.
That being said, Don't go out and buy a 15 watt sub and think it'll be fine. One day you're favorite song will come on and you'll crank it up and then BAM! you won't have a working subwoofer anymore. All you'll have is a 20 pound paperweight.
