SVS Subwoofer with vintage amplifier

Ok so what i have going is a pioneer SA9100 amp with some klipsch RP600. I want to add an SVS subwoofer. How do I do that while making sure the mains arent getting full signal and also maintaining the sound quality from my amp to the mains.

I know that i can run speaker wire to the subwoofer and then to the mains... but does passing the signal through the subwoofer alter the sound to the mains ?

I think that the speaker level output is just a passthrough. The sub doesn't alter the signal. You'd still get the full range of signal to the mains.

I haven't been able to find a link that verifies that, though.

Your amp has pre outs/main ins so send RCA to the sub "RCA in" L/R and then from the sub "RCA out" to power in and your sub plays everything below 80hz and your main speakers play above 80hz.

From the SB1000/PB1000 manual

Quote:
Line Level Inputs

These inputs are used for line level connections to the subwoofer. For a single
mono connection to an AV receiver, use the R/LFE input.

For 2-channel applications, use both the Land R inputs.

Line Level Outputs

These outputs are used in 2-channel applications to high pass the signal being
sent to the loudspeaker amplifier.

The line level outputs feature a fixed 80 Hz 12 dB/octave high pass filter.

if the SVS subwoofer has HPF out. The Pb12-NSD has these features

Remove jumpers from main in / pre out from SA 9100 or if no jumpers, there must be a switch near the main in/pre out, set the switch to separate.

Connect 1 pair of RCA from Pre-out from 9100 into Line in of SUBWOOFER
Connect another pair of RCA from HPF out of subwoofer to Main in of SA9100
