r.sok Posted September 12, 2016 Report Share Posted September 12, 2016 -stinger 6000 series rca -Memphis 12 gauge wire -Memphis 4 channel amp -Boston acoustics 6.5lf pro series components I notice when the stereo is all the way down or really low volume I get some type of slight feedback from my tweeters. It males a slight Whirl sound. no hum/whine & it doesn't increase with volume. It only happens when the tweeter is on the "0" setting. -2/-4 it doesn't do it at all. Any clue to what it may be?

r.sok Posted September 12, 2016 Author Report Share Posted September 12, 2016 Crossovers are mounted inside the door cavity on top of deadner & power/Rca are on different sides of the car. I've noticed it only happening with these components & my hybrid audio components. On cheap sets it doesn't do it at all Link to comment Share on other sites More sharing options...

r.sok Posted September 15, 2016 Author Report Share Posted September 15, 2016 Does it go away if you turn the amp gain all the way down? Yeah with the gain all the way down the noise isn't there. But if I put my gain all the way down then my speakers don't play that loud. Max volume is 30 & my hu clips around 25 Link to comment Share on other sites More sharing options...

Max volume is 30 & my hu clips around 25 What the numbers are aren't relevant for anything more than a reference point for how you set stuff. If you have to crank the gains way up your HU isn't putting out a decent voltage. The high quality components really do let you hear more lol. Did you change anything else when you changed components?

ShadeTreeMechanic Posted September 15, 2016 Report Share Posted September 15, 2016 You might need a pre amp to drive the line so you can keep the gain down. Some EQs have a pre amp built in. I did this and it made a big difference. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...
r.sok Posted September 17, 2016 Author Report Share Posted September 17, 2016 This h/u puts out really low voltage. I'm guessing somewhere around 1-2 volts.... Yes that low. Changing the head unit isn't an option for me. Kind of hard for me to give up the features it has to offer. Android based, Internet browsing, app downloads, essentially it's a tablet. Is there something you guys would recommend to boost my rca voltage without compromising sound quality? Link to comment Share on other sites More sharing options...

The only thing I changed when installing these components are the connector ends of my wire to fit the midrange. The speakers do sound really good with perfect balance "eq set flat" but the real low volumes during morning drives kind of drives me crazy. All the loud features are set to "off" & eq cutting doesn't make a difference Link to comment Share on other sites More sharing options...
