connecting high level sub

Need advice please. Thinking of buying a active sub woofer with a high level connection. If I connect the sub in parallel across the main stereo speakers will it change the impedance of the output, ie the 4 or 8 ohm output now becomes a different value and possibly blow the amp, or is the impedance of the active sub so high that it has a negligible affect on the amp. Am i thinking correctly and that is now high level subs connect into the circuit, or do they connect in some other way? I would need to use a high level connection as my valve amp has no line out - just input paths. thanks Phil H
