High pitched noise in speaker


Could be an alternator problem. Bad ground wire or just old bad wiring.
If you have an amp then the power wire is to close to the speaker wire.

JL Audio 1000/1 v2 distortion problem


Make sure all your connections are tight , really tight . Check ground , make sure it's to clean shiney metal. Three subs are going to have a low ohm load if paralleled . These amps are not 1 ohm stable ,if below 1.5 ohm's you will have problems. They need to be series paralleled to raise the ohm load. These amps put out the same power from 4 to 1.5 ohms.

Bought some speakers, they're big and heavy but they don't have any indication of what ohm they are, i connected my turntable and all i can get is a high pitch noise from the speakers and no audio...


Hi,
most of the speakers are " 8 ohms " ..the very old German made ones are 4 ohms only ...

which RCA jacks did you connect your turntable to Receiver ?
if "phone" ,it requires without "PREAMP" output from turntable.otherwise you will ruin the circuits in Receiver and make high pitch sound.....

Try with any other input on the receiver (i.e AUX.) and test it...
unless your RCA cable broken it should work well.you can try with another cable..and remember to make a solid ground connection between turntable and receiver as well..it is a must.....

Take care and if it succeeds please Remember to rate/vote and give me 4 Thumbs Up
for Helping out the Community :)

Hope this helps!

I looked up the correct way to wire my JL 13.5W7 1.5. Therefore it said to wire it in parrallel. I understand this will put it at .75 ohm. As I start to turn it up it sounds great, very loud but once the...


1000/1v2 Class D Monoblock Subwoofer Amplifier Specifications:
  1000/1v2

Rated Power:
1000 W RMS @ 1.5 ohm - 4 ohm (11V-14.5V)

THD at Rated Power:
<0.05% @ 4 ohm

S/N Ratio:
>95dB below rated power (A-weighted, 20 Hz - 20 kHz noise bandwidth)

Frequency Response:
5 Hz - 250 Hz (+0, -1dB)

Damping Factor:
>500 @ 4 ohm / 50 Hz


According to the chart your amp is only stable down to 1.5 Ohms, so running at .75 Ohms the noise you are hearing is the amp clipping (running more power than it can handle at low ohms)
I would suggest wiring it in series, or you could adjust the gain on the amp until the popping goes away.

Hope this helps.

PYLE PT2001X 3300 Watt Professional DJ Power.just had question about running this amp in bridged mode 4 ohms, here's some amp info 3300 watts total power bridged in 1 ch only.1650 each ch in stereo mode...


Hi,

In bridge mode the minimum load will be 8 Ohm.
If you are using 4 Ohm speakers, it will mean you will give each side of the amplifier a 2 Ohm load.
Thats to much for this model.

Kind regards,
Gerard

High pitched noise coming from speakers after installing stereo


check your wires if they are too near some big power wires and move them away from these high powered wires or check your grounds and make sure its a good ground by scrapping the connection until bare metal. Also its a possibility rca's or wires are getting pinched or not fully connected.

When i turn the volume up my jl 1000/1 amp turns off then turns back on when the volume is low what can i do to fix this?


2 things, either your pushing too much power into the imputs (if using high inputs) and clipping the signal, or your running the ohms too low (lower then the amp can handle safely) by running multiple speakers of too low an ohm each. For example if your amp is 4 ohm stable and your running 2 4 ohm speakers in parallel that makes 2ohms and the amp can't handle a load that low. You can consult your manual and it will give you illistrations of wiring and ohm loads

Noise coming from the speakers


The right speaker is not tighly connected. Check for
loose connection at the terminals, that causes to oscillate (high noise)
