Bigbannana,

Did you get a chance to see (feel?) if the THA was overly warm?
Could it have been thermal protection shutting the amp down - I understand why you've done it, but having the amp sandwiched between what is essentially two bits of carpet can't be doing much for its cooling?

I used to come across this when friends woud install amps upside down onto parcel/stealth shelves, not realising the heat sinks of their amps wouldn't work upside down.

It;s such a shame you've had anightmare from beginning to end with this 'upgrade' (I'll surround the word in inverted commas, so as not to offend!)

Selfishly I'm hoping you've just got a duff amplifier, or the currently less than ideal is adversly affecting it, because I really want the 5 channel/component upgrade/Earthquake sub upgrade to sound as good as I hope it will, yet be as reliable as a factory install.

Think I need to get together with Gizee and take him up on his offer of a listen...
