Jared420 Posted August 4, 2010 Report Posted August 4, 2010 Got my Aq 2200s last night, hooked them up real quick to test them and they worked great so I unhooked it all so I could make good connections today when it was a better time to do it than midnight last night. Hooked it all up today and they are working great, still need to fine tune a bit but the only problem that I probably didn't notice last night, is that when I am idling I am getting for lack of a better term "ground noise"? maybe, its just a steady rumble from the subs and its louder the more I turn the bass knob up. If gain is 0 I either cant hear it or just barely. goes away completly when I get on the gas. it will come back a little bit if I am coasting down a road giving no gas and the rpms drop very low. like I said just at idle basically. I left my truck on for a few mins with the gain up just maybe 1/5 so i could hear it and I jiggled and checked all my rcas and grounds and no change at all. what could be causing this? where else can I look Quote 2012 silverado ext cab ltz 24" kmc rims AudioQue 2200 Pioneer AppRadio Alpine mrx f35 4 channel Bose mids and highs Iraggi Alt + stock alt in a DC power dual alternator kit Yellowtop+stock under hood 0 gauge Knu wire Big 3 4 gauge stinger (4 chan wiring) 3 DC 10'' LVL3 with LVL4 parts
memphisBred Posted August 4, 2010 Report Posted August 4, 2010 Are any of your power wires touching or close to the RCA's? When I hooked up my Sundown 125.2 to test my AA mids, I got a ground noise coming through my mids. Checked all the wires and noticed my Knu power wire was in direct contact with RCA's. Ever since i cleaned up and straightened my wiring, everything has been all good. Quote SMD Super Seller/Buyer Audison----Hertz----Rainbow

dugee81 Posted August 4, 2010 Report Posted August 4, 2010 Try grounding the headunit better maybe? Add another wire from the harness in the back to a good spot behind the HU Quote 200a alt. by Excessive Amperage hc800 under hood & 2 Deka 9a31 in rear 1/0awg + big 3 SAZ 3000D HDC3 18" @ 2 ohm

Add another wire from the harness in the back to a good spot behind the HU From what spot? the aluminum plate on the back of the HU? cuz the black ground wire that comes out of the back is like 16 gauge tiny wire Quote 2012 silverado ext cab ltz 24" kmc rims AudioQue 2200 Pioneer AppRadio Alpine mrx f35 4 channel Bose mids and highs Iraggi Alt + stock alt in a DC power dual alternator kit Yellowtop+stock under hood 0 gauge Knu wire Big 3 4 gauge stinger (4 chan wiring) 3 DC 10'' LVL3 with LVL4 parts
Jared420 Posted August 5, 2010 Author Report Posted August 5, 2010 any tips on grounding my head unit or ideas of what else could cause this noise? I have never had this happen before only thing that has changed in my setup is amps.

huh?do-what? Posted August 11, 2010 Report Posted August 11, 2010 any other suggestions? I thinks its kind of weird it stops when I rev it up does that mean anything? your crossover may be filtering out the noise at higher frequencies. Quote God damn its hot today. My balls are stuck to my leg.
skittlesRgood Posted August 11, 2010 Report Posted August 11, 2010 some amps do that. Quote If I answered you in a well mannered, informative way, you asked a good question or had a good attitude.

keepinitloud Posted August 11, 2010 Report Posted August 11, 2010 try with the headunit out of the dash and turned on take some wire and strip a length of it long enough to wrap around the metal part of the rca's and hold it to a grounded point and see if thats the problem if not start checkin your grounds make sure your rca's are not in contac with the power wire in any way also have your alternator checked make sure it does not have a bad diode good luck Quote 06 chrysler 300C Hemi one mmatts dreadnaut 15 powered by a planet audio vx 2200d fosgate p200 running planet audio 8" midbass drivers and super compression tweeters stock battery and a stinger spv44 Irragi 300 amp alternator big 3 1/0 http://www.stevemeadedesigns.com/board/topic/55075-system-in-my-300c/page__view__findpost__p__763656__fromsearch__1
