Answer 1

First off, no one who has answered this question so far has any idea what they are talking about. The way you describe it, you have a mono line-level RCA connection on your receiver and speaker level 5-way binding posts on your subwoofer.

If that is how it is then you are working with a passive subwoofer that needs an amplifier to work. The cheapest and easiest thing to do would be to get a plate amp off Parts Express or other company for $100-$200 which will give you all the power and flexibility you need. If you want to go for more power and more expense, a pro audio amplifier would fit the bill. If you are unsure about how to hook up everything, the manual that came with your receiver should have some diagrams that should help. If not, go online and search some A/V forums.

If worst comes to worse, a technician should be able to hook everything up for ~$20. It really is not that hard to do once you understand all the connection.

Answer 2

You need 1 mono amp (if 12volt you need 110 t0 12v adapter so you can plug in wall) you need sub crossover to make your speaker have bass and your speaker plus rca cable
1. plug sub preamp cable back of your amp to new amp 2. plug speaker wire from new amp to sub crossover
3. wire sub crossover to your old speaker
4. you now have a sub
However you can buy a sub with built in amp for $69 up ready to plug in

Go 15! 15 inch Btl will get alot lower and louder than a 12 inch Btl You can also look into digital designs z series...

Answer 4

run a single RCA cable from receiver to either sub connection, if the sub has a Low Pass (hz) knob turn that as far towards 180 as possible, that will have your sub running, it does not connect like other speakers. your other option (if you sub has 4 of the regular speaker connection is to run the front speaker cables to the "in" on the sub and then run wires from the out's back to your front speakers. I'd suggest sticking with the RCA cable though.

Answer 5

It seems to me that you have a non powered subwoofer. I think you have to get a separate amp to power the sub. Try to look at your subs owners manual for connection options or do a search for similar subs like yours. Good luck.

Answer 6

If I understand correctly, you just want to use a spare speaker you have as a subwoofer.

This may not work.
