Page 4 NOTES ON SUBWOOFER WIRING • VT4880: Users may choose to wire both 2258 (18”) components in parallel to one (1) channel of a MA-3600 or MA-5002 for (4) ohms load. In this case each amplifier channel drives one VT4880. If two VT4880 are wired in parallel, the load is two ohms and there will be ...
