Hi All, Been following htese forums with great interest and my first post is HELP!! I recently purchased the M&S THX500 Series all wired up to my AX3 no problem... I then wired up the THX 500 series sub's 2 built into the 502's one from the amp to the input then loop from the output to the input... But nothing!?!? Has anyone got any ideas or has either the same set up or same amp speakers that could shed some light on this. I have even put it back to the original set up and still no BASS!
