you can't relaly do it directly. you need an amp/head unit which will let oyu hook up a sub and external speakers. most of them typically do more such as have dvd settings, tuners, everything. its pretty much your home entertainment system

There's an EQ as well as a frequency response issue from the TV's audio section, and what he may really be missing is more of the lower mids versus what a sub will reproduce, but I needed to find out if it's even possible with his TV before walking him down this path.

Very simple, and easy to do. We used to sell big screens and subs all the time for folks that didn't want surround sound but wanted a little thump... The best way to get better sound is a decent surround or even stereo receiver and then some good speakers, but anyway...
1. Make sure your TV has variable audio outputs. This is pretty straight forward- if it has preamp level outs, check your owner's manual to see if they are variable. This means that if you turn the volume up or down, the preamp level goes with it. In some cases, the back of the TV will say it:

Note: Some TV's do actually have a dedicated subwoofer output. Pioneer big screens come to mind. If this is the case, skip step 2.
2. Find a subwoofer that has a built-in crossover that's halfway decent. Just about any decent sub will have this. Make sure that the crossover is active.
3. Connect the two together.
4. Set your crossover on the sub to anything lower than 100 hz. You're sending full range audio into something that can only do bass, so make sure you are cutting it off relatively low. Don't wanna blow the thing.
Sit back and watch something like Jurassic Park.

Yeah what he said! 
A lot of TVs have pretty darn good speakers on thier own, so a sub will be one of the biggest improvements. Remember a sub isnt a sonic sledgehammer to the brain like many of the car audio companies try to make it out to be....
(Actually MTX and Kicker come to mind with that type of marketing strategy...lol) And it need not be large - typically a single 10 will get the job done just fine - remember in home audio you dont care about building SPL...
