Engine noise coming through one channel

I just hooked up my JL e6450 amp and as I drive and my RPM's increase there is a noise in my right rear channel that increases in volume with my engine speed. What could be wrong here?

This sounds like alternator whine. Do you have the power and ground connected to your battery, or through the accessory power? Make sure the power and ground wires are sufficient size, and connected to your battery, and make sure you have the power wire fused no more than a foot or two from the battery. If it is only on the right channely, maybe this wire is getting feedback from another wire. Seperate the wires if this is the case.

Wires create magnetic fields, and if a speaker wire is next to a power wire or something, you will hear a noise, typically high pitched whining.

Engine is stalling when turning right


H JL, As the problem is apparent only when turning right, I believe there is a problem with the idle up solenoid or the vacuum pipes connected there. The unit is situated on the steering box and increases engine RPM when the engine comes under increasing load, when demand is increased while turning. Regards John

I want to hook up subs and a amp in a 2008 saturn vue how do i do it


If you are planning on using the factory stereo you will need a line level converter. You basically connect two of your speaker channels to the line level converter. That in turn will give you a line level out (RCA cables) That line level out can be fed to a two channel amp which would be where your subs would hook up to. If you do this however you will lose two channels of mid range and highs ( your rear speakers ). Downfall to this approach is that some line level converters are susceptible to alternator noise.

If you have an aftermarket deck this will be much more simple. You simply run your RCA outputs from your deck to your external amplifier. Aftermarket decks typically have front rear and subwoofer outputs. That means you can drive a four channel amp for your front and rear and a two channel amp for your subwoofer. This is the recommended way to go.
For hookups I just suggest buying an amp kit that is comparable in power rating to your amp. If you buy a 500watt amp make sure your wiring kit can handle at least 500 watts.

Something is shorted most likely. Check the wiring to your speakers. Check especially for stray strands of wire where the speaker wire connects at the amp and speakers.

Jl audio 500/1 amp low ohm light at high volume


I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.

I bought a 500/1 jl audio amp and also a w7 10 sub


if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

Jl audio e6450 cuts out above mid-volume


take a look at the power, ground and remote wires. the power and ground should be a minimum 6awg in wire size, and the remote wire at least 12awg. it sounds like your drawing a lot of power,so smaller wires usually mean more heat...the amp will turn off into protectedmode if it gets hot or is used for along period of time,so on any road trip make sure if isnt msothered by sleeping bags,coolers etc...just like any major electronic component, it needs room to col off.
