Amp as a power source?

I'm thinking about adding a dual 4'' cathode kit to my trunk to give my subs a sweet look. For a power source to power these bad boys, could I attach the power wire to the power terminal on my amp and use that as a source? Thanks.

sure, that would be fine... and if you didnt want them on all the time, wire up a relay and throw the relay with the remote wire, so they would come on when the amp comes on

or you could use a relay and power them off the stock trunk light.

could I just install a switch? Also, should I put an inline fuse in?

yeah you can use a switch and def put an inline fuse in there so you dont get any fires!

so that is all I need then??

i wouldnt do that, i had a set of subwoofer neons hooked up to my amp power wire and they dimmed everytime the bass hit

anyone else do this and have any kinds of problems with it? Thanx

I did it way back when, but I never had any problems.

I am just gonna do it anyways to see what happens, f it

i think it all depends on the power wire for the amp, i was using a wire that was way to small for that amp, and maybe thats why i had the lights dim, but if it works with no problem or even if there is a problem then let us know man

i just took out the light from my trunk and wired it to that.....they were on all the time so i just switched the neg - .

imo dont because if your running alot of power from your system and you get in the habit of running stuff of your power line, they will dim, especially if you dont have an amped up alternator and battery, and thats bad for the lights and such.
your best bet is to just run a power line to a switchbox with a fuse in that and have power leads going to your different lights throughout your car and then ground them to nearby chassis parts. it makes things really easy and if something stops working you dont need to look all over to find out whats wrong.

Pull the fuse for your interior lights, snip the stock trunk wires, and wire up the transformer to them. That's what I did for my trunk, now I have a lovely blue glow whenever I open the trunk

For anyone doing the same, don't run directly off of your remote line, it will start to mess with your headunit, but you can use the trunk leads directly w/out any problem good for a few lights.

the only thing you use the remote wire is to send a small signal to the amp to turn it on and not to wire up lights, but if you want the lights to turn on when the HU is on then run a relay, it should work
