Can I run a sub?

[calegrant]

I have a fairly old Reciever but I want to run a sub. The reciever puts out plenty of power, but it doesn't have a sub specific output. It only has two mains, and two remote speaker jacks. Can I run a sub off of a speaker jack, or should I invest in a newer amp and worry about a sub later?

I would invest in a new receiver and worry about a sub later
Good Guys is going out of business and they have some good deals on Denon,Pioneer Elite Yamaha receivers

Have fun shopping

Most do. Just check before you buy.

Instead of speakers wires from receiver and sub from receiver it would be speakers wires to sub and then to receiver.

Connect your receivers speaker output to the speaker level input in the sub, the run the speaker output from the sub to your speakers. Set the crossover on the sub appropriately.

But you still won't have 5.1 sound, so a new receiver, as suggested above, is the best way to go.

I'm running a sub off my Marantz 2270. Just because one only has two channels does not mean one should be denied the use of a sub. That's why many come with a left/right line in and speaker inputs.

True, and with a receiver that doesn't have a sub pre-out, there's no reason you shouldn't wire it that way.

But you can get better sound (in theory) by using a receiver with the sub pre-out. This frees up the amp from putting out those frequencies below the crossover setting and cleans up the mids and highs.

(This is the way it was explained to me, anyway)
