So basically the Crown XLS1000 amp I got works perfect.
Super quiet, smaller and lighter than I thought it would be, easy to set up (took literally 30 seconds), and has plenty of output.
I basically cut the wires from the inside binding posts of the LT500 amp, rewired the entire inside of the speaker (since the existing wiring was crap), hooked the speaker up to the binding posts on the inside (most difficult part lol) and screwed the plate amp back on.
Hooked up the LFE cable from my denon, to the crown, then made a 2 ended banana plug wire and hooked it up bridged via the directions and plugged the other end into the LT500 amp posts and VOILA!
Sounds great, had to turn up the gain to max, and turn the subwoofer channel up from how I had it before, but then I watched The Dark Knight Rises on blu ray and had to turn it down quite a bit as to not disturb my neighbors, Good thing its easy!
Would reccomend as a replacement for those looking for standalone solutions. Best part is you don't have to deal with the annoying auto-on/off crap from the LT500 now, you have a functioning button to use.
