Single rca to a y adapter going to eq.2 then rca to 1/4 to amp.
Can you take a picture off how you have it connected.

I have two subs running in stereo from my EP4000 amp and wire mine like this.


Single rca from the sub output of the receiver (I use a subwoofer cable as I had two spare) going into input 1 off the EQ.2.

The a rca from output 1 off the EQ.2 into a 1/4 rca jack adapter into input 1 off the EP4000.

http://cgi.ebay.co.uk/GOLD-6-35mm-1-...item1c1a5fb1b2

I run my EP4000 in parallel so that I am duplicating input 1 to input 2 so this way I only need to use one input off the EP4000. The gains on the front are still independant off each other so you can still adjust the levels according if you need to. It just means that the signal on both outputs is exactly the same.

My switches on the back off the EP4000 are as follows:

1 - Right
2 - Right
3 - Right
4 - Right
5 - Right
6 - Left
7 - Left
8 - Right
9 - Right
10 - Right

I used to have my gain on the EP4000 on max but now have it on 24db and the onkyo sub trim level on +7 so the input signal going in is stronger.

What receiver are you using?

It may well be that you will need to purchase a samson s converter to boost the signal but most receivers should have a strong enough input signal.

Let me know how you get on.

cheers

Re: Building Custom Subwoofers!!!!

Cool, you shouldn't have any voltage input issues with the onkyo 805 receiver.

cheers

Re: Building Custom Subwoofers!!!!

See pic attached. On the bottom off the remote you can hit CH Sel button until you see subwoofer come up on the on screen display on the onkyo. The use the plus and minus to increase and decrease the level.

The better way is to go into the setup menu, then speaker set up and level calibration and adjust it from there.

This way it records it in so when you turn the receiver off and on again it doesn't change back to what you had previously which is what happens when you just select the CH Sel button on the remote.

You can use the CH Sel button just to get the levels correct.

cheers
