bkdv: Will this work if my vehicle has no factory amp, but is a 6 speaker system with door tweeters? Or is this only for 4-speaker applications?
Santiago Lopez: Im thinking about buying this Alpine product but the question is would it work on my Kenwood deck. I upgraded my speakers to JBL's 2 6.5 and 2 4x6 in the back of my pick-up and i just want a little bit more accurate sound and bass! Also i have no subs and no big amplifiers.I don't want none of that.
agodzadza95: can i install 2 of these for more power? if so would it double it or just add another 20 watts?
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 firstname.lastname@example.org
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.
p jr: is the Alpine KTP-445u also plug and play like the Alpine KTP-445a with alpine cd receivers or does it have to be wired in like a regular amp?
p jr: can I still run my mrp m500 for my subs? I have the cde 153 bt alpine car stereo that has 6 channel preouts.
Dave Caruso: can you plug two of these amp back to back for more power?
Kahron W.: Does it work with the cde 143bt?
Cal McNamara: I was told by a rep at crutchfield that this will work with my Pioneer 4400HD (14 watt RMS), but I just don't want to be wrong, because it looks like everyone uses this on Alpine head units exclusively. Can I use this power pack?
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
