Needed some help. I replaced all door speakers and wanted to replace the rear sun with a 2way 6 1/2 speaker like the one i put in the front doors. The truck came with a double din and i believe the factory amps are still hooked up. I installed one of the other speaker to try out the sub out put and the speaker sounds really low while all the others sound good.

If it's still hooked up to the factory amp, then it could be using the integrated electronic crossover. This will yeild a lower volume because the frequencies are limited. If the speaker is not designed to produce those efficiently then it won't be loud. There is a reason they make subwoofers. One, they are designed for efficient low frequency output and 2, they can usually take a lot more power. Because low frequencies are difficult to reproduce, they need more wattage to match a typical 2-way speaker. There are some threads on here on some mods for that location but a simple sub box and small amp will serve you best. Don't bother with a 6' sub, it will never satisfy....and probably do more rattle in that location than anything else.
Is it hooked up to your sub output? Your internal crossover is probably only sending audio below a certain frequency to the speaker. The sub output, if you have it hooked up, isn't designed to be full-range.
Is it an aftermarket double-DIN or the original Toyota double-DIN?

The frequency response of a standard 6.5" full range speaker won't go low enough to pick up the frequency output for the sub channel on the factory amp. Get a true subwoofer and the sound may improve. New design small subs work ok but you need the proper enclosure to make them sound decent. Best bet if you want any real base it to ditch the factory amp, put an 8 inch sub back there and an amp designed to push it.
If you're just looking for standard sound in the back you can wire the speaker in series with one of the door speakers. You'll experience lower volume levels from those two speakers but it will work.

I run a single 12", and I wouldn't even waste my time installing anything smaller than a 10" sub. 6" and 8" will just tease you, but once you start turning up the volume a little they will quickly sound like garbage.
I disagree. While the size of the sub changes things the speaker quality, the enclosure, your amp selection and how you tune your set up also make a huge difference. I've run many set ups that varied from 8" to 12" subs and combinations of those sizes. One of my set ups had two 8 inch fosgate punches (high end not the best buy version). Yeah it wouldn't vibrate your teeth out but it never sounded bad at any volume level. I currently run two 10's and they sound great and provide a nice bass feel throughout the truck. All comes down to what you want, if you just want a little thump and good sound quality the right 8's will work fine. If you want to rattle the rearview of the car next to you then you better step up to 12's.
Getting g 8's to hit hard is exactly that, hard. If minimal to moderate is the goal, a 10" sub would be ideal, a 12" would be awesome, and a 15" would be crazy. Who the heck puts a 15" sub in the soccer mom 4x4 anyway? What a waste of both space in the interior, and a waste of speaker when getting that big! Oh wait, yeah, I put a 15 in my rig! I live the damm thing and wouldn't change it unless I went to dual 12's, but for the time being, the 15$ sub in my rig kicks ass! I was a bit apprehensive as I hadn't had some boom in a rig for a while. Now I'm constantly parking the rig where it's within eyesight, and behind a big gate overnight. I'm planning on building a custom box (sealed, as I want a cleaner sound) and ditching the ported box I have in there now.
