A:AnswerIf you receiver indeed has two sub outputs then it is best to use two of these kits although I don't necessarily recommend this kit as it has significant latency issues.
A:AnswerAnytime I subwoofer has two inputs Left Channel and right Channel and you only have one output from your receiver you definitely want to check the manual on your subwoofer as it will definitely go over this. In most situations you would just use the Left Channel input on your sub.
A:AnswerI use a Yamaha sub with a Sony amp that also has a single sub-out. On my model of sub, the manufacturer suggest to use the right sub input port if only one is used. This question is not specific to the rockfish transmitter, as you would have to resolve even if direct wire.
A:AnswerThe rockfish package has all you need. the Transmitter will wire to the outputs on you amp, and then a receiver/amp will power your speakers. Check the specs, the wattage from the rockfish unit is limited to the output of the rockfish unit.
A:AnswerFirst you need an amplifier
Then would work
This thing just cuts the wires from amplifier output channel to where you want to put the sub as long as u stay in range
A:AnswerNo, this is the wrong product for that. What you need is a Bluetooth transmitter/receiver. This is to plug in a speaker that utilizes RCA connections. The most common use of this is for hooking up a subwoofer on the opposite side of a room from a receiver.
