Dumb question, JBL sub from car  

Run what you have for now; save up, and purchase the matching rears/surrounds and a good sub.

The Dayton is a good sub. I own two.


Huh? The Dayton goes down to 25hz. How low do your fronts go? I'm sure that guy knows nothing about the Dayton.

There are reasons for using a sub even if the mains go down as low as the sub.

If you want to try the car sub in the house, that would be fine, though usually car subs are not powered and home subs are, so you would need to buy a separate amp. If you go that route, keep in mind that most car subs are low-impedance (because cars have lots of amps but very few volts) and most home amps don't like low-impedance loads.

So the obvious solution to that conundrum is to use a car amp, but now you have to get a voltage converter and the wiring/installation is not nearly as clean.

Now you see why folks don't use car equipment in the house ... go with the Dayton or save up some money and get a better sub. Your 4Ts only really hit to about 40Hz, so you do need a sub if HT is your thing.

Amps designed for subwoofers (see Parts Express or other similar vendors) can handle 4 ohms, which most, but not all subwoofers, are rated at. You would need an enclosure that was large enough to allow the installation of such an amp.

I would recommend just buying a home theater sub in kit form to save a few bucks or you could purchase a new enclosure and then install the amp mentioned above and use your existing driver.

If no $..
Then go to CostCo they have a 10" 100W KLH subwoofer for $79..
