Description Features Crutchfield Hands-on Research Accessories
 

The KTP-445 connects to any 2005 and newer Alpine headunit that uses a black power harness. It will not work with the CDE-100 receiver.

Want a simple way to kick up the power of your Alpine receiver? Alpine's "Power Pack" amplifier increases your receiver's power output to 45 watts RMS power by 4 channels — plenty of power to drive high-performance speakers or keep up with a big subwoofer amplifier. Best of all, you install the compact Power Pack by plugging it directly into your Alpine receiver's wire harness — no extra wires to run, and no other connections needed.

Note: The KTP-445 Power Pack won't work in systems where an outboard factory amplifier is still active. You'll have to bypass the factory amp if you want to upgrade your power with the KTP-445. Please contact an Advisor at 1-800-297-9469 to check compatibility if you have any questions.

Great for intermediate sound February-04-12
Reviewer: ibd2328 from Coeburn, VA  
I have this installed in my BMW 330i with lots and lots of customization. The amp is almost perfect size for most installations, however, bmw spares no space when putting cars together.  I have this installed above my fuse box behind the glove box.  The wires are extra long which gives alot of options for placement.  Installation is literally a snap(plug one end into your alpine HU and the other in adapter that came with the HU).  At low to mid level volume this thing sounds amazing for the price.  I have the 4 focal tweeters paralleled with my 4 mid's so each component is not getting the power needed to maximize sound. Eventually I plan to run another outboard amp to the tweeter's and run the power pack to only the 4 mid's.  I listen to alot of rock and country so I like punchy bass, guitars, keyboards, and all the instrumental highs associated with tweeters and components. Although I have this pack essentally running to 8 speakers it still manages to push them close to their max.  The Focal tweeters coming off this thing sound ungodly.  

Alpine CDE-123 HU,  4- Alpine type S 4" in front doors and rear deck,  4- Focal TNI 1.5 tweeters in front cabin and rear deck,  2- Earthquake SWS 8" under each front seat,  2- type r 4ohm dvc 10's in custom closed box with about .85 cu ft per sub. in the trunk  1- Fosgate T1500 amp running to the type r's paralled at 2ohms  1- PDX 2.150  running to two sws earthquake 8" at 150x1 at 4ohms a piece

Adds a nice punch to the system. Easy install with Alpine head unit.


 
Can't live without it. January-24-12
Reviewer: AaronF150 from Baltimore, MD`  
I installed the alpine power pack when I installed my w-910 head unit.  Never hear the head without the powerpack, but I am quite sure there is no way it would sound as good and loud as with the pack.  I barely ever go above half volume and its loud enough I can sing and no one can hear me over the music, which is a good thing.  bottom line is, if u like music, u need this power pack with your head unit.
