patrick hogan: 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?
patrick hogan: 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
Crutchfield: Honda, The 16 watt RMS power rating is what the amplifier can put out
continuously. The 45 watt rating is peak power, the amp is only able to put
out that kind of power for short periods of time. They are two different
ratings for the same amplifier. RMS is the most reliable number to use when
matching it up to a new pair of speakers. Speakers are also rated in RMS
and peak power. Make sure to use RMS when matching a radio/amp to speakers
Hope that helps CrutchfieldTV 800 555 9408
danibwr: Does this work with my Alpine CDA-9851R? Thank you.
KrazyRMjumps: hey I have a dodge ram and it came equipped with a 430n alpine head unit
and a 10 channel alpline amp all from factory. would I be able to ad the
powerpack to it?
Crutchfield: @dcarriger Good question. There are no provisions for mounting the KTP-445
power pack. It plugs directly into the harness connection on a compatible
Alpine stereo and the Alpine’s stereo harness connects to the output of the
power pack which wires to the vehicle harness. No mounting required. Feel
free to call for additional assistance: 800.315.0030--Crutchfield
Crutchfield: @Bobo2600 Yes indeed the KTP-445 power pack is compatible with the Alpine
CDA-105. You can find both on Crutchfield, or just call us. Thanks for the
question, 800 555 9408
Crutchfield: @EastCoastGuitarist The possibility that you'll blow those 30 w RMS
speakers is certainly there. After all, you'll have 50% more power than
they can handle. However, if they are halfway decent speakers, I'd say give
it a shot and if they blow, go ahead and replace them. Doesn't sound like
they are great speakers anyway. CrutchfieldTV 800 315 0030
Crutchfield: Gotcha, You can get Alpine removal tools one of two ways. You could order
them directly from Pacific Coast Parts (Alpine Parts Dist) 800-421-5080.
Or... You could try local Alpine car stereo shops, they probably have a
bunch in a box back in their install bays. It takes about 3 seconds to
remove the radio, maybe you can find somebody that will give you a set of
tools, or just remove your radio for you. Worth a try. CrutchfieldTV, 800
greenlight2600: Yeah I paid 150 w/ tax and all I noticed was a few volume louder no change
in sound quality, but I took it back as I saw it wasn't worth it,
Crutchfield: @Zone6atlantian Please accept my apologies for the delayed response. No.
The Alpine power pack is only recommended for use with compatible Alpine
car stereos. I’m sorry I don’t have better news for you there. Feel free to
call for additional assistance: 800.315.0030--Crutchfield
Crutchfield: No problem, happy to help
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
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:
Bobo2600: hey guys i was wondering if this would work for the alpine cda-105? thanks
Crutchfield: @illSPOKEN207 The KTP-445 connects to any 2005 and newer Alpine headunit
that has a black power harness. The CDM-9821 was a 2004 Alpine. I'm not
sure what color harness it had. But it's looking like it's probably not
compatible. CrutchfieldTV 800 315 0030
thepatester: Installation was super easy. Took about 15 minutes start to finish (it was
my first time attempting hu removal). Everything sounds crisper and more
detailed. I highly recommend this especially if you have after market
speakers. Love the Alpine brand, and Crutchfield's customer service is
Fabian Fant: This might be a stupid question but does this amp only work with Alpine
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
zZZzzzSnooze2nd .: @crutchfieldtv Same thing here, Same sound. There is noway to hook this up
the wrong way. I got mine for C$150 Tax in & I didn't think it was worth
it, so I taken it back for refund.
gradyboi2: I have a question about eh ktp-445u. I have the ktp-445 and noticed on this
one it has gain inputs for the front and rear is there a big sound
difference between the two? Did they make any improvements like adding a
full range phase instead of low and high options? Please let me know as
soon as you can thanks.
Jeff I: 45 watts RMS to each speaker, correct?
Crutchfield: Hi Brandonc308, Great news, the KTP-445 is definitely compatible with the
Alpine CDE-102. We have the removal keys for most factory radios, and you'd
get them for free with the CDE-102 from Crutchfield. If you need radio
removal keys for an aftermarket radio in your dash, try googling
"Crutchfield Partsearch" They should have them for you. Call us to make
sure you get all the installation gear you'll need for your specific
vehicle. CrutchfieldTV 800 555 9408
Crutchfield: @EastCoastGuitarist Well, you'll have 15 watts more than they are rated to
handle, which is 50% of the 30 watt RMS rating. I guess you could look at
it either way. Kickers are decent speakers, I've owned several pairs over
the years. I've also blown several pairs because I fed them too much power,
specifically too much bass to a set of 3-1/2" Kickers. So, you'll need bass
blockers or a head unit that has a high pass front speaker output. Call if
you need help, 800 315 0030
Crutchfield: @omegaSQ That's definitely not what i would have expected, you should
certainly notice an improvement with the Alpine Power Pack. If you bought
it from Crutchfield, you can call Tech Support at the number on your
Crutchfield invoice. I’m certain they can help you make sure it's connected
properly. It's one of the reasons to buy from Crutchfield. If you bought it
elsewhere, you can purchase our Tech Support. Call us for more details I
hope that helps, CrutchfieldTV 800 315 0030
youngsimba09: I've been meaning to ask.. what's the difference between the KTP-445U and
Jeff I: So you do not add the the power that you already have from the deck? This
replaces that power completely? So if thats the case each speaker will be
getting 45 watts RMS right, since its 45X4. So that would be a total of 180
watts RMS right?
onebad70ss: Does this unit power down when you shut your vehicle off? I have installed
it with an Alpine CDA-105 unit and I seem to have a battery that isn't as
strong as it should be in the mornings.
Zone6atlantian: does the power pack work with non alpine head units
Bobo2600: @crutchfieldtv i just got mines hooked up and it sounds great and all, but
when i speed up and shift gears my music cuts off, and it makes this
clicking noise when i switch from hi pass to lo pass when my car is off and
the clicking noise is amplified threw the speakers when my car is off, any
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:
Mark HVACsales: Double your power...gain 3db ...that's it.....
zZZzzzSnooze2nd .: @Bobo2600 Well i have the Alpine CDA-105 & it sounds the same with the
bbearhug: I have watched this video a few times and I am certain that I do not have
enough connectors in the box based on what I see here. I cannot figure
where he gets that female connector. THen he says to plug the cable from
the amp into the receiver which will not fit into my cd player.
4ERHG: I Have A CDE-9848RB Is it Compatible With KTP-445? Thank You...
Crutchfield: @shaggythemaster Yes, the harness for the KTP-445 has a turn on lead. Also,
splicing into the wiring for this product at all will void the warranty. It
is only designed for use with compatible Alpine head units. Hope that
helps, call us if you have more questions. Crutchfield 800 315 0030
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.
youngsimba09: thanks! so the 445A will be better because no splicing is involved right?
if I have an alpine headunit that is
StarsMarsRadio: It's easy to install anything in a jeep
Crutchfield: Hi danibrw, Yes indeed the KTP-445 is compatible with the Alpine CDA-9851R.
CrutchfieldTV 800 955 9408
illSPOKEN207: will this amp be compatible with a Alpine CDM 9821 head unit?
Crutchfield: @KrazyRMjumps While your factory equipment may bear the Alpine name, it
does not offer the standard Alpine aftermarket wiring harness and,
therefore, will not connect properly to the KTP-445 powerpack wiring. I’m
sorry I don’t have better news for you there. Feel free to call for
additional assistance: 800.315.0030--Crutchfield
MrDrMONTENEGRO: HI! Will this unit change sound quality ? I have alpine 9887 and I am
afraid of defecting beautiful sound ??? What is your experience ?
Crutchfield: @imfercho That's correct. CrutchfieldTV
BlackHondaCivicHatch: Yes I understand that part. My question is, what is the total RMS power
output after adding the KTP-445.
Crutchfield: The power pack simply offers more wattage for powering your speakers. It
offers no equlization and will not affect the audio adjusments of the
connected stereo. Feel free to call for additional assistance:
Crutchfield: Tingtang123, Yes, this is designed to power your front and rear speakers.
In systems that have separate tweeters, they are usually run off the front
speakers, so the amp should be able to power them both without a problem. I
hope that helps, CrutchfieldTV 800 555 9408
