Audio Annoyance..., my subs thump when the lights go on Options

AAAAAAAAAAAAARGH!!!!!

my subwoofers thump loudly whenever i step on the break, shift into reverse, open a door or turn on the lights. there is definately a DC pulse going down the audio line somewhere. will a capacitor cure this or is it just a crappy installation (BTW the audio shop that did the install is on my BLACKLIST already)

well, i've picked up noise from fuel pumps, relays, lights, cellphones, pagers, wife (that noise is constant though ) and all kinds of stuff.

If that doesn't work, then I'd recommend checking your head-unit wiring second, Because you could have a common ground with a relay to the tail lights or w/e else is causing this "thud". Hell, your RCA's could have an expansion point near a whole harness

If thru the ground: You wouldn't hear it in your speakers because they do not play at those freq; as well as the fact that most head-units have noise filters built in. Amps usually do not; for the simple fact that they need to move that power quickly, not play with it and delay the music.

If your picking up noise thru the RCA's expansion points, then you'll need to tape that up or move the wiring a bit.

thanks D-Man.
i have quieted the "constant noise" in my Celica by inserting a "BitchSwitch". 4,99$ at Canadian Tire and 1/2 hour to install . it even lights up!!! when i have a few hours to myself i will go over the wiring and see what's up. like the title says it's an annoyance, not a problem-- for now.

peace

P.S. say hi to Jack for me (luv the sig)

I'd call it a problem!

WTF is a "BitchSwitch"? Ground loop isolator?

hahahahahaha!!

it's a remote shut off (illuminated SPST rocker switch) for the subs. you referred to "the constant noise" coming from the wife in an earlier reply. i have the same problem...it's too loud, there is too much bass, don't drive so fast, do you ever signal your turns, watch out for the kid on the bike...that constant noise. and you are right the "thumping subs" is a problem it is probably doing no good to my amp or woofers. i have to do this sooner than later.

thanks for the follow-up.

I've never in my live wired nor seen a sound system w/o a manuel power switch. There is nothing "bitch" about it.

No, it's probably causing harm to your amp and/or subs. When it does that, it's a excess flow of power seeking a way out; if it did not blow out the subs, it would blow a fuse (depending on your wiring and equip) possibly destroy equip faster.

I'd reccomend on jumping on that first thing. Or keep your manuel switch handy, and kill the amp when you know that'll be happening. I just dont wanna see your equip jacked up and have to buy new. (btw if you need a new amp, i've got 6 ) lol.

Yes the W.I.F.E is a very loud audio component. however it seems to have remote power coming from outside the closed circuit line, and despite my best efforts, i cannot remove this device from any of my audio setups. The only thing I've found to counteract the effects of W.I.F.E. are alcoholic and/or car related. It seems that this device cannot be heard over a roaring engine. I recommend a 12pk and some performance tuning
