Infinity Entra Sub Subwoofer Questions & Answers

How do i fix my infinity entra 10 inch 150 watt powered subwoofer. fuse is good, green led is on so it is getting power
Best to start at the beginning. You have it connected properly? Are you using the line level, direct or speaker inputs? What output on your receiver are you using?
Have you adjusted the volume control?
If you have everything correct, are you the original owner? It's an older model so if you are the original owner what happened when it stopped working? Noises, fade out, just wouldn't turn on one day.
Are you capable of doing some minor electrical work? Can you read a schematic? Can you recognise electrical parts? If the answer to any of these last three questions is no, you need to take it to someone that has the ability to do electrical repairs. If the answer to all three is yes you can fix this yourself.
After some time on, the
No speaker spontaneously makes popping noises unless it is driven so hard the mechanical parts are crashing into each other. The amp is probably stressing out due to heat, which would explain the delayed onset of the symptom and its disappearance after a cooldown.
Perhaps you are overdriving it??
How do u hook up
Maybe if you described the setup with exact model numbers for everything involved we might be able to answer with specifics.
You could poke around her for the Entra Manual for YOUR model.

What they do NOT explicitly tell you is that the amp in the sub is not for your other speakers running off it's Speaker Level outputs. They're just there as a pass-through if you use Speaker Level from your own amp.
Line Level (RCA) IN to the sub will NOT pass anything out those Speaker level outputs.
Infinity Entra Sub 150 no sound or power
I had the same problem. When I opened it up, the fuse was blown, and it was a pain to find the fuse it needs (3 Amp, 250 V slow-blow fuse, 5x20 mm). Also, the 2 large electrolytics (big purple things near the amp) and one small capacitor were all blown. For 4 fuses, bought seperately from, and the 2 electrolytics and 1 capacitor, it cost about $20, plus almost 20 more in shipping, which still isnt bad considering the original price of the sub. However, the tricky part is that you have to know how to use a soldering iron to take out the old components and put in the new ones.
My Infinity SSW-210 Servo Subwoofer quit working yesterday. The light is on and the fuse is okay but there is no sound coming out. Does the sub have another fuse inside?
Unlikely, but open it up and take a look. Some help here.

Dec 26, 2009 - I picked up an Infinity Servo Subwoofer yesterday, but not quite sure as to how to ... The SSW-210 or SSW-212 have two drivers and no port.
Infinity tss 750 sub-woofer when powered on immediately pulls speaker in and has loud humming. no inputs hooked up, only plugged in to ac power source.
The loud humming is the sound of AC mains - clearly your amplifier is receiving an input from somewhere and possibly into the front end.
The hum could be induced by radiated energy from nearby unshielded equipment, it could be the result of an accidental hum-loop or could be because the amplifier power supply has a fault.
It is usual practice with amplifier construction to ensure unused inputs are shorted to ground by switching or by additional contacts and wiring at the input sockets. High gain high impedance inputs can cause a great deal of unwanted noise if they are not shorted.
I suggest you read the instruction manual and perhaps Google a few hints and tips about amplifiers and stuff.
