noise

Been working on an install on my '19 Civic for a few weeks now. I decided to run a JL Fix86 to clean the signal and fix the bass roll-off that is built into the Factory HU. After getting everything set up and multiple attempts/tweaks I consistently get a constant static noise coming from...

I just finished upgrading the stereo system on my Jaguar XE. I have the outs running into an MS-8 and then into 2 4 channel Dual Class D amps. I have all the grounds run to one location via a distribution strip hooked to the master grounding place on the vehicle (battery is in the trunk.)...

Ok so i had installed a cheap pair of component speakers last month with a very cheap amp. Well the tweeters had static, so i thought it was the amp or speakers. I recently purchased a set of Morel Maximo 6's and a MB Quart ONX4.80 AMP. Well guess what the static is still there. The White...

Hi guys, not sure where this post belongs, figured I'd try here. So I have an 01 WRX, with a pioneer headunit installed by the previous owner, there is no amp at this stage. I believe the unit is an AVH-X2600BT, or something very similar from pictures I can track down. I began to notice the...

I installed a Nexus 7 in my car, and I decided I wanted to install a volume knob since the on screen volume adjustment doesn't work well while driving, and other users struggle to change the volume using the volume rockers. Basically I have a bluetooth receiver linked up to my N7, then the...

I just recently replaced all of the factory speakers in my 2004 GMC Sierra Crew Cab with Infinity Kappa 6.5s. I also installed a Kenwood Kac-8405 720-Watt 4/3/2-Channel Amplifier to power the speakers. I have the power wire run down the driver side of the truck and the RCAs run down the...

Hey guys. I just recently installed a new system in my car. I am running a Kenwood KDC-BT755HD head unit, Infinity Reference 6030cs in the front and Polk Audio db691 in the rear. They are driven by a JVC KS-AX5104 amp. I have a REALLY bad whine coming from all speakers. This is the setup: - Ran...

I have two crescendo audio FT1 tweeters(80 watts rms 8 ohm each) both with cross overs running on a autotek amp I think its a 1000 watt MAXX 2 channel(1000.2 but I highly doubt it actually produces anywhere near 1000 watts), and I recently put my car in the shop for a tune up(oil change, ac...

I have recently installed a JBL MS-8 processor, after having read many of the reviews and several threads on this very forum. My goal was to bump up the factory output level, fix up the sound stage, and add a subwoofer to the system. To be clear, I wanted to both improve the quality and the...

Straight to the point, here's the set-up and then the problem... Audison 5-channel Voce Amp. Active Audison Voce components in the front taking up 4 channels and the 5th channel for a JL W6v2 ProWedge (sealed box) sub in the trunk. Kenwood Excelon head unit. Set-up questions so you don't have...

Alright folks, I've been messing with car audio for a while now, but my alternator whine has me stumped. The situation is as follows: The car is 1996 Honda Accord 2.2L I have two Boston Accoustic GT series amps feeding front comps and rear coaxes. I also have one Alpine MRX-M240 for the subs...

Alright, so I just finished adding a new amp and rewiring a few things. I have a boston Gt2200 for my front comps and now a newly installed boston Gt2125 for my rear coaxes. After connecting the rca's to my rear amp, I get very noticable alternator whine and other noise. The noise is only...

Please help me diagnose and correct this alternator whine. I am somewhat of a noob, so please be gentle....... Car: 2001 BMW M5, battery is in the trunk Setup: Kenwood DNX9980HD (double din GPS, top of the line a year or so ago, recently bought used for a reputable person), JL HD900/5...

Let me just start off by saying that this is my first post at DIY, and as such I may have put this in the wrong section. Please excuse me if that is the case. I have searched briefly for threads containing a similar problem, but came out empty handed. Nevertheless I may have missed something. If...

I have heard alot of people say that one problem with the Rockford Fosgate 3sixty.2 is that it introduces a noise floor problem (an audible hiss). I had the same issue when I first installed mine. At first, I didn't really care too much since I have a convertible (= loud) and I couldn't hear...

I have an Alpine iDA-X305 and the imprint processor PXA-H100 which mates with it. I just hooked them up and I was super excited to listen and then I turned on the stereo.... NOISE! Before I hooked up the PXA-H100 the stereo was completely quiet. If you had the volume set to its lowest...

I went active with my 880prs, and now I'm getting a high pitched whining noise that does not change in pitch with the engine at all. It is completely constant. When I turn the unit or just the screen off however, it goes away. Any ideas?
