Tj1 Posted July 12, 2018 Share Posted July 12, 2018 I recently bought a Cherokee for a daily and the audio get to quiet when at a stop or braking. The deck is aftermarket and has a sub/amp combo. Any ideas on how to stop the spectre? Sent from my SM-G892U using Tapatalk Link to comment Share on other sites More sharing options...
gogmorgo Posted July 12, 2018 Share Posted July 12, 2018 I haven't seen it on aftermarket decks, but it's not uncommon for factory radios to have a "speed-adjusted volume" setting. Basically it gets louder as you go faster, then less loud as you slow down. It's got three settings for how agressively it changes the volume. Since replacing my colander, er, muffler, I've found that the "high" setting got too loud, then too quiet again so I've turned it down to "medium". Might be worth looking through menus, or if you know make/model, finding a manual for the deck online, to see if you have a similar feature.

87MJTIM Posted July 12, 2018 Share Posted July 12, 2018 Funny story. My wife and I purchased a used 2003 Chevy Sub 2500. I did not come with the owner's manual. The radio has the "self adjusting volume." As the speed increased, the radio volume gets louder. We found this to be very ANNOYING, especially for people in the back when we tried to have a conversation. I would turn down the volume as I sped up, then increase the volume when I slowed down. One day I was complaining about this with my daughter in the truck. She looked at the radio and asked "What does this button do?" She pressed it. Problem solved!

Sir Sam Posted July 12, 2018 Share Posted July 12, 2018 Stock XJs don’t adjust volume. Link to comment Share on other sites More sharing options...
gogmorgo Posted July 13, 2018 Share Posted July 13, 2018 Nope. But it is a feature some decks do have. Even if they aren't hooked into the computer or anything, they could still potentially read rpm in a normal 12V induction spikes from coils firing and adjust volume dependent on rpm. Not that I know for certain there are aftermarket decks that do this, just that it is a fairly common thing that wouldn't be completely ridiculous to implement. But I'm wondering what the OP has going on. No idea what deck he's got, how it's wired, etc. Link to comment Share on other sites More sharing options...
Minuit Posted July 13, 2018 Share Posted July 13, 2018 He didn't say how much amp he has, but my first thought is a voltage drop. Link to comment Share on other sites More sharing options...
