Different popping sound than the other guy's

[ladykilla85]

Hey guys, new here-not to car audio- looking for some help. I have a popping sound that occurs when I switch tracks, power on/off, or cut the volume to 0. I've watched the sub and it's moving a pretty good bit.. more than 1" I imagine. Some DC is making it to the speaker I think because it's flexing considerably. Most of the time it doesn't "pop" louder than I normally play my music, but it's VERY noticeable.

I just bought a '96 Toyota Camry ( 2 door //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif ) and I had a MTX 7000(I think.) sittin' around so I bought an amp.

The amp is a MTX 7000 as well, ironically. It's old school //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I got it from the music/record/car-home audio/electronics repair(me) shop I work at. It seems to be working fine.

I built a 2 ft^3 box with a slot port(not important atm) to put it in because the box I got it in was crap.

The car came with an older Sony Xplode //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif I have an old basic but trusty Pioneer that I have yet to test out in the car.

I also have a cheap .5 f cap installed.

4 gauge to the back, then 8 ga to cap/amp. 8 ga ground on the cap and 4 ga ground on the amp. Scraped the paint off under the carpet and put a screw in the body.

Thanks for reading and I'm hoping I'm overlooking something easy/cheap.. Budget Bumpin' lol

Oh I also tried putting a switch on the remote input of the amp coming from a constant 12v so that the amp remained on even if the HU was or not. Still popped.

Is it a single pop that is followed by, mainly, the action of turning on or turning off your CD player?

If so, what you have described above is normally known as "turn on/off pop" and occurs when there is a bad ground.

First of all, I would put the Pioneer in ASAP.

Second of all, it sounds as if you had secured your ground coming from the amplifier properly, so my guess is that it's at the head unit. Try to ground your head unit ground wire directly to the chassis, without exceeding over 18" in length.
