Why do I have only one sub out? Instead of two for RCA's

So I just swamped out my old pioneer unit for the jvc kw-av61 and I noticed a huge difference in sound quality. Anyways I want to hook up my subs and there seems to be only one dedicated sub out female instead of two for the RCA cable. Do I have to by an adaptor or just plug only one RCA in there? Thanks in advance for the help!

Since there is no stereo component in bass you only need one output. You can use a "Y" splitter to the input of the sub amplifier.

Y Splitter?! That's what I thought, can't wait to buy one and start wiring my amp again! Thanks Coby7 for the speedy advice!

you could do that, but a dedicated sub output is always preferred...it will have the LPF built in, and most radios will even give you the option to choose the crossover frequency and sub level on the radio

most sub amps will be wired mono as well, and often if you just plug in the right or left input (depending on the amplifier) it will play without needing the Y-adapter
