Hey, does anyone have a like wiring diagram to show how a amp and 1 sub should all be connected to the car deck and battery???

THANKS

you forgot remote to HU

ok thanks dude

i connected my ground to my seat belt thing that connect to the car body. is that alright or not

And wat about the remote wire

I wouldnt advise on the seatbelt location. It really needs to be on bare metal. The remote wire extends from the headunit to the amp itself....

...and it that diagram, as to not confuse the OP, change the color of the wire running from the batt to the amp to red, not black...

yeah, sorry about forgetting the remote wire, lol

and the black power wire, i had all ready used red for the rca's, lol i was bein lazy

LOL....you forgot the Remote Tun on lead...how the hell is his amp supposed to get the signal to turn on?!

Also it is a good idea to run you RCA's down a seperate side of the vehicle then the power wires (power,Remote turn on) as you could get that engine wine or signal interference.

I believe crutchfield has an amplifier installation writeup and video so try and check that out for a more visual idea.

ya thats the noise am gettin an engine whine exactly, but i moved the cables from each other and its still the same i moved them like 30cm away

No...Ok.....

Your amps power wire (which runs from the batt to the amp) should be placed down the opposite side of the car as the RCAs.

If your batt is on the left then run the amps power wire from the batt down the left side of the cars interior and the remote turn on wire as well.

Run the RCA's down the right side of the vehicles interior to the amp....if you're still getting engine noise then check the RCA's and other connections.

Read the links I posted and then watch the vid.

if you have that whine its cuz your ground isnt at a good spot, find a bolt that connects directly to the car's chassis and scrape off all the paint.

Grinding is easier then scraping //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

oohhh..didn't see he was using the seatbelt.......definately find a place in your trunk that has an existing bolt...remove the bolt and either sand it down to bare metal (no paint and no primer) and connect your ground wire to that bolt and bolt it back down in place and the shorter your ground the better.

ok will do

 

[philmetz 10+ year member]

hey ppl iv tried grounding everywhere on my car but i still get that engine whine noise!!! i even got a piece of metal and stuck it into the ground outside but jack not workin, so i think it could possibly be ma AMP. its a pretty cheap one, like lucky star or so... is there any quick fix or so i can do on it like adjust this or that???

THANKS

Reground your headunit. Your problem is that your amp has a better ground than your HU and your signal cables are not electrically isolated from the ground of the HU or the amp. The current seeks the lowest resistance path to ground. If your HU has a bad ground and you amp has a better one, the easiest path is through the RCA. Because of the design of the car's alt there is a small ripple in the voltage that it puts out. This ripple isn't enough to cause radiated noise (see below) but it is enough to be really annoying when introduced directly to the signal.

If I see one more person promulgating the myth that you need to run your RCAs on the other side of the car from the power wire, I'm gonna give them an e-kick to the nuts. Unless you have some really serious problems with your alt, the tiny ripple in the alt's output voltage is not going to cause enough of a current flux to create the expanding and collapsing magnetic field required to induce noise. Also consider that the current flowing through the power wire is proportional to the voltage in the signal cable. In periods of high current there is also the highest voltage in the signal cable and a high voltage signal is less suceptible to induced noise. Factor in the most basic of shielding and you are pretty much talking about induced noise being a non-issue. Finally figure in that if you use a chassis ground, every bit of current that flows throught the power wire also flows through the chassis of the car. Unless you plan on moving the RCA as far away from the chassis as possible as well, there is no point in trying to isolate the RCA from the power wire.
