I've been reading AVS for a little over a year now, but this is my first post.
I bought a kenwood HTB-354 kit when I started my theater as a temporary sound system and was planning on upgrading in a couple months, but I'm not going to be able to do that now. The receiver that came with the kit is vr-517, which looks like it's very similar to the vr-505, one thing the vr-517 is lacking is a subwoofer preout.
I recently added a pair of 25w aura bass shakers and just connected them to the subwoofer output. This causes the receiver to shut off when I try to turn it up higher than about -30dB. I opened up the receiver and it looks like all I should have to do is add a couple capacitors, resistors, and the rca jack in order to get a subwoofer preout. I attached a picture of the area I think it should go, and can get a higher resolution picture if it would help. If anybody can help me I would really appreciate it.
