<font color='#000000'>I have a rca home theater system and recently i bought a new rca subwoofer with a built in 120 watt amp.my problem is that there is no jacks for a subwoofer on the back of my reciever!I have hooked it up to the high end with the speaker wires from my sub out. is there any way i can hook it up to the low end.what is the difference between high end and low end inputs?I have heard low end inputs are better.</font>
