Did this video help you?

Tony Pascale: Can someones please help me, i just bought this powerpack for my alpine headunit and when i connect the powerpack and turn on my headunit it makes a loud high pitched noise coming from the speakers,

Dick Muller: Can someone tell me how to change the time on my Alpine Model KTP445A. I can't locate my instruction book.   Thanks    Email dna356@verizon.net

Darko Stajic: Hello,i have LG LCS500UR headunit and i am from Europe.Headunit has power connect Dim 16pin.Will this amp connect to my headunit?

Aaron Randall: so, you can you use with any other headunit, it just needs to be directly wired? rather than using the connection provided...?

Chris Burr: Is it less effective to have an amp that works with the speaker outs on my Alpine stereo, rather that using the 4V pre-outs...I am buying a cde-164bt

Sclernix Dewop: Couldnt I just replace the 10 amp fuse in the fuse panel to a 15 amp fuse? 12+ wire is 12g

Sclernix Dewop: I have a cde 135bt head unit. I only have a 10 amp fuse. I have heard alot of people that are using it this way and not having problems. What do you think?

Deep Roots: [Massive Edit Because I Reworded It Much Better]

I have a KAC 9104D Amp, a KDC-348u Head Unit and the KTP-445 Power Pack. I'm trying to figure out how to set this all up correctly because I didn't pay attention to how it was all connected when I took it out of my Toyota. Right now, I'm stuck trying to figure out how the power pack and head unit relate to one another in respect to the harness in the car.

Obviously the power pack has the two ends:
-One leads to the Head Unit via RCA connections which also has one blue/white wire coming out of it as well.
-The other end has the exact same wires the Head Unit has that would presumably be connected to the harness in the car.

Now, my problem is, does the head unit get connected to the power pack via the RCA connections AND get its harness wiring get coupled to the Power Pack's harness wiring, thus they both connect to the one harness in the car (like a Y connection) or does the Head Unit simply connect via RCA to the Power Pack which then gets connected to the harness in the car?
(still not sure what becomes of the blue/white wire on the RCA end though)

After that's sorted out, how would I connect the amp to all this? I vaguely recall that there was only a single thin blue wire going from somewhere between the HU and PP that went back to the amp.
Aside from that wire there were the obvious wires:
-A silver cable connecting via RCA leading directly from the HU to the amp
-A thick red power cable with a built-in fuse connecting from the battery leading back to the amplifier
-A short, thick, black grounding cable.

Any help would be MUCH appreciated. Thank you.

Crutchfield: If you are referring to the KTP-445A model ("A" signifying "Alpine-Specific"), yes. You could also use the KTP-445U but would have to hard-wire some of the primary connections. Feel free to call for additional assistance: 800.315.0030--Crutchfield

TheDaltonboii: is it compatible with the ive w530 or the cde143bt

Crutchfield: For compatible Alpine stereos, the 445A will plug into the harness connector on the back of the chassis. You will need to connect the output leads of the power pack to the vehicle harness for your ride. Feel free to call for additional assistance: 800.315.0030--Crutchfield

Crutchfield: The "U" means "Universal" as it can work with many factory & aftermarket stereos. The "A" stands for "Alpine" and is designed for use with compatible Alpine models only. Feel free to call for additional assistance: 800.315.0030--Crutchfield

Crutchfield: Yes, 2005 and newer models. The current Alpine-specific model (KTP-445A) is compatible with your CDE-121. Feel free to call for additional assistance: 800.315.0030--Crutchfield

joe citarella: i have an alpine cde-121 head unit. can you tell me if this power pack is compatible with it because i remember reading something about how it has to be 2005 or newer? thanks.

Crutchfield: Hiss can be a difficult problem to diagnose. If the hiss was not present originally, I would be sure your connections and ground are attached firmly. If you are unable to get the results you’re looking for, you may want to speak with the retailer that sold you the gear for additional troubleshooting. If you bought from Crutchfield, the toll-free tech support number is printed on the back of your invoice. HTH!--Crutchfield

Joseph Nishimiya: I have the 445U installed on my stock head unit. There is a hissing noise present even when the radio is off. I know if I turn the gain down some the hiss slowly goes away. Is there any way to keep the gain levels at at least half and get rid of the hiss? Thanks.

Jose Granado: you guys should do an install video for the Clarion XC1410

Crutchfield: No. You could use the universal model (KTP-445U) to power additional speakers in your system but you could not use multiple power packs to the same speakers. Feel free to call for additional assistance: 800.315.0030--Crutchfield
