Hello
I want to split the audio signal on my McIntosh MA5300, by removing the jumpers from pre to amp, and using a couple of "" RCA 1 male to 2 females splitters, so I can connect my 2 subwoofers to the system.
.
Question is: would splitting the audio signal affect the sound quality ?. Would the amp now be seeing the same 2 "8 OHms" speakers ? or 2 speakers with 4 ohms each ?
I am ignorant about this subject, and I would appreciate any advise.
Ty

Ok, Maybe I can help. The single coming out of the preamp out is measured in millivolts and only the speaker configuration from your speaker terminals on the back of the amp would affect the speaker impedance. You can do this without any problem. You may experience some signal loose but what the hell give it a shoot. You really should use 2 male RCA's to one Female for each channel. Then just plug one cable in to each channel to one side of the sub.

Ok, so I did some SVS manual reading and research. I am using 2 subwoofers: SVS SB12-NSD - 12". I removed the jumpers going from pre to amp off the MA5300, sent left and right pre amp ---> to the corresponding left and right inputs on the subs, then from the subs high pass out ---> to the corresponding right and left amp inputs on the MA5300. My understanding is the high pass out would only send signals above 80 Hz to the speakers. and the sub crossover will be used to determine the cut off frequency below which the subs will output. Did I get it right ?. pls advise   |

You may be degrading the signal to the Macintosh power amp. Depends on the quality of the high pass filter in the plate amp. You could try both ways and see which sounds better.
first scenario:
Y splitter at output of preamp
One leg goes to the SVS
The other leg goes to the power amp
Speakers get a full range signal that is not high pass filtered
Second scenario:
output from preamp to SVS plate amp input
High Pass output from SVS plate amp to Macintosh power amp
Speakers get filtered output that is processed by the SVS plate amp.
