i have a Pioneer HU with 2x RCA outs. Have an amp powering 2* 6x9" and one Subwoofer. I was wondering if its possible to place a switch somewhere between the HU and the amp so that i can shut the woofer off completely?

thanks in advance

Using a toggle switch between the remote wire going into the amp will do the trick.

Be careful whose advice you buy, but be patient with those who supply it. On/Off Switch for Subwoofer -- posted image.

I assume you are running a four-channel amp and you want to keep the 6X9's powered? In this case you will need a high-power switch or relay on the speaker side between the amp and the woofer. Get a relay rated for the maximum power of the amp. Not a cheap scenario... a better way might be to install a remote volume control like an Audio Control MVC or a crossover with a level control for the sub.

I just thought of a cheap and dirty way to switch off one of your RCA sends to the amp. Get an A/B line-level switcher (they make these for audio or for AV. Either would work.) Then if you literally want to switch off the subs, you could select the empty input (B side) for the send to the channels running the subs.

I like cheap and dirty....that's a good one, DYohn.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

We were messing around in my friends car. you don't need to use the rem wire from the head unit. make your own wire that goes from the battery to the switch to the amp that is powering the subwoofers. we used 10 gauge wire and the switch works great. Very cheap and very easy. all you need is enough wire and a cheap 12 volt switch.

sorry ignore my post...i first read your post as if you had two amps. DYohn's way will work the way you want it too.

yeah.. i was thinking of sticking a switch somewhere on the RCA for the subwoofer. The problem that i was worried about was that the grounding abilities of the wire might be jeopardized. However, i;ve seen On/Off switches with 3 pins. and one which says ground whereas the other 2 would be the 2 connections you want to change. How do I hook up the cable shielding of the RCA properly?

i did consider the RCA option but was worried that the grounding shield around the cable would be broken and might introduce noise. But i've seen 3 pinned toggle switches around with one pin saying ground.. if this is what i'm supposed to be looking for, how do i go about wiring up the grounding shield on both ends of the connection to the switch?

Toggle switch on the RCA is not what I was suggesting. Do not use a toggle switch on the RCA cable. Get an AV switcher like this. (Actualy that one is overkill as it is a 4-input audio AND video selector. You only need one that has two audio inputs. But get a device like that one, not a toggle switch.)
