okay the other day this guy that i know was just going to throw away a 10 inch rockford fosgate home theater sub that is in perfect condition and it still works! so i took it of course, and now i want to hook it up to my reciver on my home theater.... problem is the connections arent the same. the connection for the current sub is a rca jack and the connection on the RF subwoofer is like a normal speaker with positive and negative wires. is there a way that i can get a dongle or something that switches that single rca port to a regular positive negative set of wires?
see the series of 6 screws on both sides? im guessing one is left and one is right? and mabie it has a input and output? i have no clue, i think there was some lables above them before but now they are gone so they fell off? if it does have a input and output then would i just hook up my 2 front channels to the outputs on the sub and the sub inputs to the outputs on the reciver?
Yes that is the case! You will need to figure out which is in and which is out. Could be tough though. You could use a 9volt battery and touch the + and - of the battery to two screws that you think are for input. I would think that they will run from left to right in this order. left+ left- right+ right-. The woofer will make a scratchy sound. It may however do the same on the output terminal as well so this test may not work. Be sure to check the other screw terminals on the other side to be sure that this is not the case. If they do not make the woofer click than these are the output terminals. If it clicks on both terminals than go to plan B of using the B speaker out on the receiver. However if you use the B speaker output for the sub only, then when you run the system turn on both a and b speakers on the front of your receiver and the sub will get the same output as your fronts. You can then control the crossover and input volume at the sub if it has the controls for that. I hope this is of some help to you. Good Luck, If I can help further please post!
So your receiver will not run both A and B speakers at the same time? Last option. Go to your local HiFi store and get a speaker selector box. Be sure it is impedance matching so you will not harm your receiver. Then hook up the fronts and the sub to the box and turn on both the fronts and the sub from the box. These boxes will allow you to hook up multiple speakers to one speaker output on a receiver safely. You may loose some power but all the speakers will then work.
Thanks Kano! You are correct... All of the options I have laid out will not yield performance. But performance was never mentioned, just how can I get it to work. A mono block amp will work but I agree with you purchasing a powered sub will not be much more cash..
