Sounds like speaker is clipping (overdriving) put a meter onthe disconnected speaker and see what the resistance is,4 ohms ,8 ohms ,if the meter wont stay in one place (numbers changing constantly) you have a burnt or damaged coil in your sub, if that is not the problem change your RCA's cables to make sure it not a bad wire including speaker wires! GOOD LUCK

NHT sa-2 amplifier won't go into standby mode after 10 Minutes of no signal


Does the NHT sa-2 have it's own pre-amp? Because I'm wondering if the power off only works when it's own pre-amp is used? So when your receiver is connected it's shut off.

You could try something connected to it's own pre-amp (if it has one) and see if it goes off when there's no signal from that.

Wine noise only, no volume control


C7 and C15 capacitors bad, on main amp board, 470uf/25vdc, in +13vdc power supply circuit. BE SURE TO DISCHARGE MAIN LARGE CAPACITORS ON POWER SUPPLY BOARD AS THEY RUN AT + AND - 90VDC (180VDC TOTAL) AND STAY CHARGED LONG AFTER UNIT IS UNPLUGED!!! Shock hazard and may damage unit beyond repair if not discharged while desoldering components. Use around a 1000 ohm, 5 watt resistor across capacitor leads, if possible check voltage with meter to be sure they are discharged.

The fuse blows in the SA-WM500 whenever there is an input from the amplifier.


http://www.retrevo.com/support/Sony-SA-WM500-Subwoofers-manual/id/752ag404/t/2/


The fuse blowing is a symptom of something seriously shorted internally. What preceded the initial problem? Smoke is bad. Fire would be soon to follow without the fuse blowing. Take it to a tech.

Philips HTS3450 - high pitched humming noise until warmed up


Jeremy,

Read one of my posts:
I used a hairdryer and blew hot air into the grill on the bottom of the subwoofer enclosure which reduced the delay time from ~1hr to 5 minutes. (The high pitched noise was still there for about 1-2 minutes)

I have a ly1440 amp how can i wire it to my hk15x2


This subwoofer has (2) 2 Ohm voicecoils.
Which means you will only be able to wire a 1 Ohm or 4 Ohm configuration for your amplifier.
The Model # you listed for the amplifier is not a valid one.

If your amplifier is 1 Ohm mono stable...
you wire both (+) Sub to amp (+)
and both (-) on Sub to amp (-)
This is PARALLEL wiring and lets the amplifier SEE a one ohm load

If your amplifier is NOT one ohm mono capable - your only other possibility is a 4 Ohm load.

Wire from (+) on amplifier to one (+) on the sub
Then Wire from (-) on amplifier to the OTHER terminal's (-)
You will have one (+) and one (-) left on the subwoofer - wire them together.

This is SERIES wiring, and nets a 4 ohm load for your amplifier.

There is no other configuration for wiring one Dual 2 ohm sub.

Makeing poping noise


Although open shields on the head unit generally cause MTX amps to squeal, it can sometimes cause the symptoms you described. To check the shields, you will need a multimeter. The procedure is on the following page:

Testing for Open Shields on RCA Signal Cables

If the shileds are OK, we will have to check a few other things.
