Spaekers pop on start up

[Mappy]

2003 Chevrolet Tahoe. Bose factory head unit. Db Drive 1250 watts. 1 12" sub. Hits HARD. $330 for amp. $ 275 speaker. Tried turning the gain down on converter and thump was not Aas bad. But speaker doesnt hit as hard. Didnt try turning gain down on the amp. Assumed it would also not hit as hard.

Turning it down on the amp probably wont do anything anyway. But I don't know what else to tell you. The price on the amp doesn't meant it's great because I would take a sq1200 for 60 dollars cheaper over that. Good luck!

Wasnt saying the price mattered.More than one person was saying they never heard of DB's B4.. Just putting it out there.

Turn On/Off Thump

Turn on thump can vary from a slight pop to a mind shattering, teeth rattling BOOM! This thump is caused by the audio circuitry stabilizing when power is applied. Most amplifiers and source units have muting circuitry that lasts a couple of seconds to allow these fluctuations to subside before passing a signal. However, if the amplifier un-mutes before the source unit or any other accessory, you better watch out. Here are some things to try if you have turn on thump.

1. Verify that the amp has a good audio ground reference. (See rule 6 of the Ten Commandments of noise free installation.)
2. Dont install the system so the amplifiers can be switched on when the source unit is turned off.
3. If you still have thump, add a turn on delay module in line with the remote turn on wire to the amp.
4. This concludes the section on turn on thump

Likely a grounding issue. Also DB doesn't make very good quality stuff.

Ehh, certain amps do this no matter what, in my experience. Especially ones with low SNR.

My truck does it turn off and on. I can assure you I.dont have any wiring issues. Some amps just do it like he said
