i have a question about how to integrate a pair of deep hemp subs. i have a few choices:
1. run the speaker cables from the same 8 ohm taps the XRS's are using.
2. run the speaker cables from one of the other amplifier outputs, e.g. 4 ohms.
3. slave the speaker cables from the XRS's; i.e. amp -> XRS -> sub.
there's no pre-out on the eico, so that option isn't available.
option 1 is the most awkward, option 3 the most convenient. but how will option 3 affect sound quality?
