    I have the same problem, except I am using the Sub Out through an RCA plug and sub isn't auto powering on. How do you diagnose this? I saw someone said with a multimeter. Where/how should I be testing?



    P.S. I also tried hooking up another source directly to the sub through the RCA jack and didn't work either. It should turn on if any signal is reaching the sub, not just sub 100 hz level audio, correct?

Hi Ron,

It sounds like the sub is not auto turning on, or has no audio output, and or the sub driver itself has failed. Do you have a multimeter, and we can diagnose the unit? :)

regards
Graeme

How do I connect the YST-SW45 sub to a different system


It's a standard non-proprietary standalone self-powered sub that accepts any input one could want. Your unnamed electronics will be the determining factor. Manuals spell it all out.

When i put my ear to the front of the sub, it makes a sound more like a rattling / grumbling than a clear bass sound. Is this normal sub function or is there something wrong?


It sounds like you subwoofer may have a blown speaker.
If it is new, take it back and replace it.

If it's not under a warranty, take the case off and examine the speaker. If you see a tear in the fabric part of the speaker cone, or along the edge... it is a "blown" speaker.

These can be fixed, but you will more than likely have to take it somewhere to get it done. If there is a company near you that does professional car installations, they will more than likely be able to fix it... or should at least know someone who can.

I have a yamaha yst sw320 subwoofer connected to a yamaha dsp-a595a amp. I recently disconnected my equipment and when i reconnected it im getting a feedback hum/noise through the sub. I've tried...


Subs don't go to a variety of connections on the amp. Let's stop guessing and stick with the prescribed one.

See page E1 regarding placement and safety.

http://www.retrevo.com/support/Yamaha-DSP-A595-Amps-manual/id/319ag821/t/2/

Page 44 - read about "humming".

If you have hum on the sub, is it there with and/or without the input cable attached?

Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.

How it can be connected to a stereo amp


hi,
if ur amplifier have a pre out, then u can connect that to ur L/R input of ur sub woofer.

if not the only way is, connect ur amplifiers speaker output to sub woofers speaker input and then connect ur speaker to sub woofer speaker output terminal. remember don't inter change positive and negative wires.

if ur amplifier have speaker A,B connection then it is very easy. connect the speaker A to ur left and right speaker. then connect speaker B to ur sub woofer's left and right speaker input. be sure to make that speaker A and B switch is in on position. the power on both and check it. ( use good quality speaker cable to connect the sub woofer)

your sub woofer is designed to work , both at low level and high level input.
ok
