If your receiver has an RCA sub out, use a mono rca cable and run it to the input on the plate amp (you can use a y-adapter to utilize the left/right channel of the inputs if you want). If your receiver does NOT have an RCA sub out, but speaker terminals for the sub, you can run a line-out convertor to convert the signal to RCA or simply wire the sub directly to the receiver and skip the plate amp. If you go with the latter, your enclosure would sipmly have the sub and a terminal cup and no attached plate amp...I think thats all correct, somone correct me if I'm wrong.

theres no out-puts at all for a sub? Then I'm bum-fuzzled...

most plate amps have line level inputs that utilize the low pass crossover. u can use one of ur receiver speaker wire outs to connect. then again, that will leave with you only 1 speaker and 1 sub. what plate amp do u have?

Methinks you mean high-level inputs, line-level inputs require a subwoofer preout, high level inputs just require a parallel wire to be run from the speaker terminals.

i thought they have both high and low level inputs? i could be wrong though.

Most do.

most 2 channel recievers have 4 sets of speaker terminals,run 2 speakers of 2 sets,then run the other 2 sets from the reciever to the inputs on the plate amp

Wouldn't they only have 4 if they had a/b switching?

receiver just has 2 speaker outs

if there is no sub out, and there is only two speaker level outputs on the reciever, couldnt he just splice the wires running to his speakers and run wires to the high level inputs on his plate amp?

I just found a reciever laying around my house that has a RCA output for a sub. what is the advantage to using a y cable to utilize the left and right inputs? Is that any better than just connecting the mono rca cable to the amp? Thanks.
