Today I purchased a klipisch lr106476 ported and powered subwoofer from the local pawn shop, just trying to give my current surround sound more depth, well I can not get the sub to turn on, the fuse was blown so I replaced that with a 250ma fuse, I believe that was the identical match, the marking was hard to read, what else could be my issue? My old sub works fine so cable and my denen avr 1713 is fully functioning, please And thank you for any help or input, my last resort is trying to open up the back to check internal connections

Opening it up is your next thing to do.

 

Did it turn on at the pawn shop?

They attempted to but failed, at the very end I personally pulled the fuse out in the store and noticed the glass was burnt, so I bought and went hone praying it was just a fuse but I have 72 hrs grace period to return it, if I open it up is their anything specific I should do and shouldn't do?

Shouldn't do?

 

Poke around while it is plugged in. 

 

Should do?

 

Look around for a loose wire that looks like it fell off something obvious.

 

If nothing is "off inside", then the amp died. 

 

If you gave anything more than $50, return it.

 

If you gave <$50...turn it passive and buy this...

Well I'm a little over 100 into it, so I will proceed to return it, any suggestions on replacement subwoofer? I currently have what is included in the Polk audio tl 1600 series

Before you buy a bigger sub...I would buy a pair of bigger main speakers...

What AVR do you have?

And bigger subwoofers have even bigger problems trying to get to 120hz.

 

Lower the task of your main speakers down to 80hz, then get a bigger subwoofer.

 

Or turn your present sub into a MBM(yes, MBM is a thing...)

 

And get a larger subwoofer in the 12" range.

 

Sub1200 Dayton to BIC F12 with "this"...

 

http://www.amazon.co...r/dp/B0002Z82LM (if you don't add "this"*...absolutely no point in a bigger subwoofer)

 

*As in, this is one example of many.
