hello to all, link : http://www.ebay.com/itm/MITSUBISHI-M-R8010-AUDIO-VIDEO-SURROUND-RECEIVER-250watts-/251163669931?pt=Vintage_Electronics_R2&hash=item3a7a8575ab

currently i'm 3d with a mitsubishi 3d set, ( which i'm looking to upgrade )
i should like to use all vintage equipment,
sourcing an all mitsubishi setup is challenging, not impossible. due to a large mitsubishi presence, between the 70's and 80's.
now first question;

1. ) from what i understand using vintage equipment, i need a mitsubishi source for the sub woofer.
what input ( on tv ) options are available.

2.) skipping ahead, i've seen a m-r8010 ( mitsubishi ) having pre out / main in bridged together,
what is the pre out, is it pre amplifier out ? what is the main in. is that the amplifier in, both being offered as part of
the internal structure of the m-r8010.

a. running two matching mitsubishi amplifiers, could i split these ( the two ) left x2 & right x2, and run them into the bridge ?
b. could i keep the factory bridge intact while adding two amplifiers.

so that connection would look like amp(A) L to amp (B) L & amp (A) R to amp (B) R which leaves the L & R male connections...

for the m-r8010: PRE out L to MAIN in L & PRE OUT R to MAIN in R ( which is how its now bridged ( SEE LINK ) so, split the
PRE OUT MAIN L & PRE OUT MAIN R with male to female RCA's & connect AMP A & B

would this connection allow amplifiers a & b to be controlled by the receiver, keeping the bridge intact, just adding more power.
