This is kinda ghetto, but...

I don't have an amp for my sub, so for a while, I just connected it up to the center channel, and had all my speakers set to large in my receiver.

This morning, I disconnected the sub, and then attached both a positive and negative input from both the left and right front channels. (There are actually four wires at the end of the sub wire instead of two.)

I really like the sound, but when I try and turn up the volume, my receiver says overload. :eek:

Is this going to go away like after the sub is being used a lot, or am I pushing too much into it?

    Geez, I'm afraid that the sub driver you're running is a 4ohm sub (like most car/home subwoofers are) so you're creating instability issues with your AVR.

    On another note, I wouldn't suggest keeping that setup....you're definitely going to eff something up.

    A passive sub does not have an onboard amplifier. Therefore, you need an amp to drive it. People often use pro amps for this as it is a lot of power for not much cash.

    Good luck,

    Passive sub is just what was explained up above, of course not to be mistaken for a passive radiator. A passive sub has no onboard amplifier, and is powered by an external amplifier only. "Powered subs" are those with built in (plate-style) amps, which offer convenience but comes at a higher price.

    Why don't you buy a powered sub or buy an amplifier to power the driver you currently have? If it's because of a short budget, we might be able to give you a good suggestion at what you should do to properly use your sub and not eff anything else up.

    If possible, yes I would like another suggestion, since yeah, I don't think I'm going to be getting any additional audio equipment from my parents besides wires...

    Edit: The way it was setup, my speakers actually became mono, so I disconnected the sub from the system completely...
