It was not difficult at all.

Since I did not perform the actual installation myself I can't give you precise details, but can tell you how the channels were bridged & the amp mounted.

Originally I had the amp mounted upside down & bolted directly to the rear package shelf sheet metal. Then I realized that with the heat sinks facing downward, the heat generated by the amp would not dissipate properly & saturate the chassis. Not a good idea. So I took it back to the installing dealer & had them mount the amp right side up & attached to the carpeted MDF board & suspended by the plumbing strapping from the original package shelf sheet metal location.

As for channel distribution, I had channels 1 through 4 bridged to power the two front main speakers, channels 5 & 6 for each of the rear fill speakers & bridged channels 7 & 8 to power the sub.
No capacitors, distribution blocks or other external components were utilized.

Though the installation itself isn't exactly competition quality & is relatively basic,
I can honestly say the sound is incredible & the bass is more than adequate for my listening tastes.

Any more questions, please don't hesitate to ask.
