When you connect your leads and get 0.2, zero that out, don't subtract it. Impedance is with AC, resistance is with DC... Without a signal going to the amp (RCA from head unit giving a null signal) you will get ambient noise. These are transistor amps, so an "amplified" null signal will hold the speakers "still". How is your unit grounded? Do you have it grounded to chasis, battery and alternator to pos with bigger wire? Could be a cheap head unit. Even wired in a simple circuit like you have here, (which is hard to tell as part of the circuit is off the table) the tiniest of drops in voltage will read as a signal. Am willing to bet the hum you hear is a harmonic or sub harmonic frequency to the clock circuit of the amps internals. I know it sounds flakey, but grounding is huge in getting rid of noise. Do some research on the "big three upgrade". When dealing with cheap electronics installation is a huge factor. I have the 8604 4 channel, and 8601 mono block and get zero noise with the gains adjusted properly, even with the head unit putting out 100% volume and no signal coming out. A small 1 farad cap and the grounding mentioned above were installed along with the system, so I don't know if that is why I have no problem and you did. Then again it is not totally out of the realm of possibilities that you managed to get two faulty units. A batch of caps or transistors that Pioneer got could have be under spec, leading to the manufacture of a few hundred or thousand units with faulty parts. Has Newegg or Pioneer addressed this problem yet? I hope so as I have always gotten great customer service from Pioneer, but never dealt with Newegg.

I don't think the hiss is from the grounds. I just installed a class D for a practice run, and it hissed too. I don't recall hissing problems 17 years ago when I was doing car audio. But, in those days, they were all class A, A/B mostly. I wonder if the class D makes that hiss d/t modulation etc. I noticed in my Honda, with radio off I had hiss, radio on hiss, speakers up, can't tell. I started the car, no hiss. So I am thinking that low voltage (12V) when car is off caused a low voltage hiss somehow. I then turned off my car. Hissssss. I turned down my gain, and gone. Started car, ... nothing. music. loud and clear. I did call alpine though, and they said bad ground ... yikes. bad ground? it's plugged into the battery

Sounds to me like the amplifier is picking up electronic noise. It's really just a bad design and not enough proper shielding possibly. I have an ART SLA1 (Class AB pro amp) that was a little noisy and sounded exactly like that and I opened the amp up and added some copper foil and sheets around the torriod and signal wires and PCB, grounded that and the noise was at least half. It's not safe to mod the shielding inside an amp because you could short it and cause a fire if you aren't really careful. One thing is that class D is a fast switching digital processing so all that fast power switching and PWM makes lots of noise that has to be filtered by the capacitors in power supply of the amp which should be fine if Pioneer designed the amps properly. Class AB might be cleaner if you live in an area with lots of electronic pollution. One thing you could also try is plugging in a iPod/phone using a 3.5mm to RCA cable and play music but leave it on pause on your test bench through the amp so you can hear the silence. If the noise is gone it could mean that the RCA inputs in the Pioneer aren't happy with the ground of the RCA cables in the head unit in your car. That would equal returning these amps and getting better ones or if other amps exhibit the same issue you have a ground issue in your car or head unit.

Agreed with earlier statements, Battery is low. I would also like to add some thing.... 1. The turn on leads, where was it connected too? The output on radio or a switched power on car? This does make a big difference. Should be connected to turn on lead from head unit. Have the head unit off when starting, should stop popping. 2. The static, or buzz you here, possible because no inputs are connected to the amp. If you connect a source, does the buzz still exists? Possible that the amp is creating buzz, trying to amplify nothing.

+John Niedermier No change even when alt is charging @ 14.5. 1) I have connected the turn on lead in every possible configuration, head unit, with and without relay, with and without delay relay, even straight off the battery. Doesn't matter if the car is on or off, multiple different grounding situations. 2) Hiss is independent of inputs, with gains set properly the hiss can be heard even while playing music. I have tested these amps multiple times in multiple configurations inside and outside of the cars and on three different test benches. No changes. My only conclusion is that these amps are of poor design. Others have not had problems, maybe they got lucky, maybe they just haven't listened closely enough. The speakers in my car are very clear and right in my face so it's easier for me to hear small things than if they were way down in a door behind a panel.

Just another reason, I personally, stay away from class d. Watt for watt class ab is louder, and they sound a hell of a lot better. Only thing is they run a lot hotter due to the wasted energy. So depending on where you live, in the summer time class ab have a better chance of overheating, after long listening sessions, unless you get a real good one. Or you could always buy one with more power than you need and just keep the gain down, that way you're not always stressing it.

Normally extra background/ground loop noise is because of a poor ground connection. If the connection is solid and it still does it, lots of folks runt the ground back to the negative terminal of the battery instead because that's the best-case-scenario to eliminate excessive noise. I see you've done that in this vid. This really is a head-scratcher. Did you ever figure out the problem? Equipment malfunction?? Or maybe it's just a normal background noise because of all the power/current flowing through the setup? I really don't know... Good luck!

IT IS THE FULL RANGE SPEAKER THAT RESONATES THOSE HISSING FREQUENCIES, subs do not. The pop is caused by gain mismatch from the music source unit. It is a current surge. The high ohm in to a low ohm amp. DSP HIGH LOW LEVEL GAIN BALANCE will solve that problem. If you must operate an amp with a higher ohm input, turn on the source unit first when it is plugged in to the RCA with all volumes lowest then put a anti surge switch between the battery and the amp, then switch on. Make sure the switch matches the current before you buy. The gain was affecting the hiss from here. On the GM A3702 the gain set lowest will not affect hiss when a sub is on with a separate source volume turned up because the sub does not resonate those frequencies. The other humming noise is outside influence. It could be a charger close to the amp or a voltage meter that has no DSP. Try a DSP filter, that will solve some of the problems. Try pure oxygen free wires for battery and speaker wire and filter the battery ground loop with a capacitor. And one last thing, Class D is crusty THD. They say it is 0.5%, does not mean it is. Those amps are cheap, what do you expect for that amount of watts. If you look at HiFi AC home amps, most are class B and have almost no audible THD, then look at the price you pay and the amount of watts you get for the cash and compare them to car amps. Then take in to account that car audio needs to be efficient with batteries so they put mosfets in and all the extra circuitry and electronics components add THD. Class D is measured at a specific volume, not up full. You do not notice it at 40 volume when music is playing.

I have Pioneer 6x9s and they generate a greater range of frequencies than any other speakers I have heard, plus they have sub bass to 27Hz. They are the 4 way and you need an EQ to balance them. When you have all your basics get a DSP FOR 7 CHANNEL. It has 8 and will give you stereo bass rather than centre sub.

Class D amps have these noise because of the way they are designed (pulse triggers) but of course the engineers are doing if not, have done measures to keep the noise at bay. Just a comment though, notice how the noise on the D9601 is much more audible than on the D8604? On the D8604 test, mic had to be placed on top of the tweeter to make the noise more audible, I'd say it is because the D8604 is for full range speaker use and may have more of the noise reducing measures in it. The D9601 on the other hand, is more of a subwoofer amp and if you put an actual subwoofer to it, the subwoofer will not produce that noise since subwoofers do not pass high frequencies. Anyways, I believe this vid, helps add info about class D amp noise. kzitem.info/news/bejne/mWN3s2hppnN7fqA

1# dont use a speaker to test a class d amp lol, you need to properly ground everything and make sure your rca imputs dont change at all when plugging in anything, when i plugged my phone into some chargers id get that hiss and whine as the engine revved as soon as i switched chargers went away, and i do notice a pop noise from the subs when turning on thats just always been there id assume theres no circuitry to slowly power things up its just like a snap of the fingers your issues could be more input related not the amps fault but the signal you are feeding it to, also my wires read 0.00 resistance so i wouldn't be surprised if that was affecting anything and you aren't fused so that doesn't limit the current draw at all

And throw that 8ga in a sub box where it belongs and run 4 gauge ofc wire cca will cause voltage drop and everything you dont want

AustinAutomotive Don't test an audio amp with a speaker? What do you want me to test with? 8 gauge is for testing only, won't make a difference. What part wasn't property grounded? I don't have this problem with other amps.

I think AustinAutomotive is falling for the "Class D amp can only produce decent sound out of subwoofers and and not speakers" bandwagon. Just trying to act like he knows his shit.

On my test bench there is no alternator. This is an SQ setup, not SPL. The reason to have a HO alternator would be to help with voltage drop. If you never turn it up enough to drop voltage then you don't need to pay for an alternator. My car sits at an acceptable voltage while I'm listening, I couldn't care less about the couple hundred extra watts I could have at full volume. A 200 watt difference in a 2000 watt system is pretty much unnoticeable.

+sherkhan808 You should be OK if you have a standard system. I have some really efficient speakers glassed into pods at the windshield right in front of my face so it's really easy to hear detail, but also really easy to hear problems.

Ya.. thats why they have been around for how long?? play some music threw that speaker so we can here how it sounds..

lol did he really say you will get a better ground connecting to a peice . of metal rather than a direct connectio. to the neg terminal on the battery? lmfao he even went as far as to say you will even get less resistance going to metal of the car rather than directly to battery haha how could you get less resistance going directly to the start of the circuit? wow idiots shouldnt give advice about stuff you are obviously oblivious to.

Because the chassis grounded to the neg on battery the actual car is not grounded the only thing on a car that touches the ground is the tires and they don't touch the ground. We are working with a DC electrical system here, it has to be connected to the neg terminal for it to work. How do you think your phone or anything else that runs on battery works? I don't see you plugging a wire from phone to the ground, do you? You ground amp to chassis because the chassis grounded (bonded) to the battery

The remote cable is only used for signal, so amp knows when to turn on and off. All the amperage comes through the pos. wire

You're using 8 gauge wire for power, it requires 4 gauge, and the speaker is wired wrong, it should be in the right side terminal when it's only one speaker being used according to the manual, hope this helps
@MotherlodeMotors

You need 4ga if you want the best possibly performance from the amp, larger wire helps minimize voltage drop so at low volume levels it doesn't matter. And even when I have all 8 speakers in my car hooked up with three of these amps the same thing happens, thanks for the suggestions though.

Using a smaller guage wire is not going to introduce noise into the system.
