When i turn on my powered sub it pops without being connected to the amp

The pop is your amp turning on before your stereo. This usually occurs with some Ford vehicles when an aftermarket stereo has been added to a factory amp. You can slow down the power with a resistor. Try installing a 1500 ohm resistor inline on the remote turn on wire.

its real simple. your under powered.

your W6s RMS at 500 watts EACH and your sending em 250RMS (half what they need)
The 'pop' your hearing is the failure to supply enough power to draw the cone back in time and collides with the next wave of sound.

prove it?
drive a single W6 with your 500/1 bridged.
i'll bet your pop goes away.

long term, get another 500/1 or jump up to a 1000/1v2.

I also HIGHLY recommend JL's in-line audio cleaner. If i recall it was like 60 bucks but waaaay worth it. makes sure that theres no distortion in the source input to your amp(s), which...keeps your subs from trying to reproduce transients and delivers only clear signal to your subs void of all clipping signals. Its an active electronic compoent.


PS: if you are pushing 12W6's, i had the same setup once...I had W3s connected to my 500/1 and upgraded to the W6s...had the same issue your describing, and then got the 1000/1. happy ending.

Loose wire or connection is causing stereo to short out, Check all connections including amp,Stereo,Speakers and make sure nothing is touching places it shouldn't

any amp over 400 watts can power pretty much any sub even one without a sub output just bridge the connection to an amp without sub output. btw a subwoofer does not use as much watts as it says on the sub it usually only take a couple hundred watts to power the sub and make it sound clean

have you got the auto ariel lead from the head unit connected to the remote connection on your amp?
if not then that is your problem, it turns the power on when you turn on the unit. and turns it off when you switch unit off.

hope this helps

This is caused because the stereo you have put in, is a high power output, or higher than the factory and puts that extra power into the factory amp systems causing the amp to surge the power to the speaker resulting in the pop sound,most newer cars use a stereo system without an internal amp so as to reduce heat and a external amp in usually under a seat or dash and a high power stereo boost the output of the amp.

amp is way too small to power a 15 inch sub. But you should get some sound out of it, not silence. You can use a 9 volt battery to test your sub, if the sub pops when the 9 volt is placed across it's terminals then it's ok. If it does not pop then your sub may be bad, or the coil may be frozen. (It can still read 4 ohms if frozen). If your amp powers smaller speakers fine, you know it's not the amp. If the sub tests ok, then verify your connecting it properly to the amp's correct bridging terminals.

first off nice choice on the amp check ur power and ground connections make sure the main battery to bady ground is good if questionable add a new one cant hurt to have extra grounds from the batt to the body make sure the amp ground is as short as u can make it make sure its grounded to bare metal if any of these dont work u may have a prob inside ur amp 

Check all the wiring. It could be a loose connection since it's intermitent. Really pay attention to the power cable, both the end for the amp and the one that's going to the battery cable.

Are you saying you connected the sony output jacks to your subs directly without any other amp? Are the sub outputs powered? Or line level? Are the subs powered or direct? need some more info please. and post the Manual here if you can. Thanks
