I just zip tied it around the metal support behind the passenger-side dash and has plenty of room. I made sure the KTP445 fuse is barely hanging down past that pannel for easy access if it ever blows.
Oh yeah, forgot something....
Alpine does now sell something called, "KTP-445U" a universal version that could be used on any headunit from any manufacturer. The good thing about it, you could run the standard setting of 45x4 like the KTP-445 did, and also have the option of running 90x2(bridged) setting. So, this will be a good upgrade for those that only want to run the door speakers.

the specs in the KTP-445U manual do not mention bridging or whether it is even
2-ohm stable.

I currently use a KTP-445, but I have some doubts. Driving down the road with the top down, the KTP-445 sort of lacked the power actually needed to run the Boston Acoustics components I run. At around 70mph'ish, the mid range sort of dies out and I could only hear the high ends only. There are times even with the roof up, the KTP-445 just doesn't cut it for some reason. And, at the back of mind, Jeremy Clarkson and Tim Allen are telling me, "MORE POWER".
I should of actually spent a little extra money for a JBL MS-A1004.

It might be a bit expensive but it's the smallest 4ch Amp with 100watts RMS I've seen so far. I was considering of ditching the KTP-445 and shove the JBL one in the trunk(on the side) so it could be fine tuned.
