subwoofer switch

[Wilkz]

so i want a turn off switch for my sub. could i run my remote wire through a switch and back to the headunit ? i dont like having just a switch for my subs because im only going to use it for a quick turn off when i see cops or w/e. this should work right ? i heard that if you run the power switch and you leave it on it can drain your battery. so thats why i chose the remote wire.

i would suggest you use a control relay. subwoofers pull alot of current and a normal switch isent rated for very much current flow. basically, your relay operates like a switch. only difference is your using a switch to actually control the coil in the relay. you hook a switch up normally only you put the relay coil either before or after the switch (I'd suggest after) when you toggle the switch the coil gets energized pulling the plunger in and turning the normally open contacts to normally closed (just how a normal switch works) this turns your subwoofer on and off without heating up the contacts on a typical switch. just make sure your control relay can handle the current, they normally say on the top of the relay what its rated for. there prolly have to go to a automotive shop to get them, normaly relays run on A/C and i dont ever work with DC operated relays but i know there out there. (I am an Electrician). the main issue there is the fact that A/C produces inductance while D/C does not, thats the primary way the contacter i just explained works.

Rockford fosgate bass control switch is what I have.. works great...

^^^ that works. it plugs into your amp right? i have one lying around.. i never use it. im too lazy to route it into my cabin. i just installed a switch to the rem wire. nothings fried up.. everything works well. if i dont want my amp on.. just hit the switch off.

That would be the way to do it. No need for a relay on the remote wire.

true dat ^^

is that a variable resistor? i wouldent mind one of those some songs my sub is way to loud some its just right some its not loud enough. my old mtx amp can with one but my alpine dident. my type x can handle 1000wrms and i only got it at 5-600 right now. but my amp goes right to 1000rms. one of those variable db controllers would really be nice

yes, you can put a simple switch on the control wire without a relay since its a low current signal wire. to your amplifier/subs its the same effect as cutting the car off. it's just like putting a fuel cutoff switch on the fuel pump

well duhhh lol some people dont even hook up remote wires. dont ask me why i always have.

on a power supply wire i would put a relay too, but it's just not necessary on a signal wire. relay would be just one more thing to worry about

If i want to put a switch on the wire from the sub to the stereo, would that be pretty simple? can u just pick one up at bestbuy or an audio store?

You would probably be better off going to an auto parts store. They should have many different types you can pick through.

Radio shack would work as well.

My remote wire on my deck that came with the car doesn't even work. The deck that also came with the car installed worked but I had sold that for parts money and I wanted the Ipod deck anyway. I just routed a switch to act as a remote wire. I mounted the switch on a blank switch panel where the foglight or other buttons would go on the left hand side of the steering wheel. Worked good for me!
