Adding an external sub to system 6

[Mooseman]

I have a Gorgar dum dum dum dum
And a spare external sub from an old surround sound system.
I’ve read how people connect from the internal speaker to high level inputs on a sub but unfortunately my sub only has low level input or sometimes called line level inputs. Any one know how I can hook it up? Or should I just get a new speaker for the pinball cabinet?

You can get high level speaker to low level line converter, I bought one that I have somewhere and didn’t use it. If I can find it you can have it if you want to try.

I’ve seen something that may be similar on eBay for car systems. It was some small box of tricks that had about 10 wires that I wouldn’t have a clue where to connect?
Does that sound similar to what you have?
If you find it would be much appreciated
Cheers @M4carp

Hi Moose,
You need a line level converter. They vary in quality and price. Try and buy one with a turn on delay(this stops popping from the speaker input ) and adjustable line levels. Here’s a picture of one.

Here’s a link to one we have used in the past that is average....

XTRONS LINE OUT HIGH HI LEVEL TO RCA LOW LO RCA CONVERTER SPEAKER ADAPTER | eBay

Two Channel Hi-Lo Line Out Converter is an electronic device that allows any stereo to be easily connected to an external amplifier by connecting directly to the high level speaker output and converting it into a low level female RCA connection.

This one is a little better, but none of them are great as they no longer contain a ground loop isolation circuit, so you will pick up a bit of “noise”........

Hope that helps. Any more info just d.m. Me Moose.
EDIT: The connects2 ones like @M4carp has are good as well, we have used those many times......
