Our old soundbar quit working so I'm looking for a new one to make our TV loud enough to hear on some channels with low volume. Last time I got an Insignia sound bar for like $50, this time I'm looking at an ONN soundbar for around $30. But I notice there are some speaker amplifiers made to hook up stereo speakers to a TV that go for around $30-$50. And I have some old Yamaha NSA636 speakers sitting around that I haven't ever used very much. Would I be better off just getting a cheap amplifier and using these speakers? thanks in advance!
