Alpine KTP-445U: bit.ly/2nAIuVc
The Alpine KTP-445U Power Pack is a 4-channel amp that can be connected to nearly any stereo, including factory stereos, and then stashed behind the dash or in another small area. It's a straightforward upgrade that can really take your system to the next level.
Our expert shows you how to install the Power Pack in various situations in this video. We connect the speaker outputs of the Alpine amp to the factory speaker wire as a part of installing this amp with a factory radio using speaker level inputs. To connect this amp with an aftermarket radio (RCA connectors), the process is basically the same -- cut the factory wire, and connect outputs from the amp to the factory wires out to all the speakers.

This is the best!!! Thanks for such a great explanation.

@Kevinb1821 3 года назад

I love this amp. I put this in my 2005 mustang gt years ago. 45 watts rms is more than enough To power your 4 speakers super loud with no distortion. This amp is about double power of any standard aftermarket head unit. Using this keeps my trunk clean. All I have is just one amp in the back powering the sub without having to run a bunch more wires to the back of the car to power 2 amps.

@Wingnut353 Год назад

@@joshymcdaniel9233 if you bothered to actually measure you'd fine that you have to get into the $700 head unit range before you get anything over 14W ... literally every head unit on the market regardless of what it says can only do about 12-14w per channel with 1% distortion... those 50W numbers are at 10% distortion which may even damage your speakers and will sound like trash. These amp packs acutally can put out 45-50W per channel...

These sound excellent. I also want to add to this great video , Recommendations to NOT ground this radio to the aftermarket wiring harness along with the radio ground. (Twisting 3 grounds together) as this may cause engine noise. Chassis base will do great . Find something metal (not painted) and use a tapping screw to drill a hole then use a ring terminal (included) at the end of the ground to contact the metal , and fasten AND WALLAH! No engine noise

@Ray-xc2jv 5 лет назад

This amp doesn't seem to need a large power wire. I'm planning to run a 8 gauge down to the harness power wire. I'm wondering if you did the same. Also, will grounding the amp directly to the battery prevent noise since it gets a direct path to the supply?

@crutchfield 5 лет назад

The power pack is made to work with most stock stereo power leads (minimum 15 amp circuit) which are commonly just 18-22 gauge so, it certainly does not require an 8 gauge run. Running 8 gauge won't hurt anything but it's certainly not necessary. If the stock system does not provide a quality ground connection at the stereo, you can ground to the vehicle chassis or all the way to the negative terminal on the battery.

@Crutchfield, I'm using a factory HU and have an amp using high-level-input (tapped into rear left n right speakers) to power a 10" sub. Will the RCA pass-thru on my amp work to provide sound to the Alpine Power Pack? Or, does the RCA pass-thru only work when the amp's sound is coming from an RCA input? Is 1 pair of RCAs all I need to power the Alpine Powerpack? My idea is to use the Alpine Powerpack to give my rear aftermarket speakers more power, but also use the other 2 channels to add 2 6.5" speakers.

@crutchfield 5 лет назад

Great question. I think it will depend on the amp. Some can pass through either speaker level or line level inputs. If you know the model number you can connect with one of our Product Advisors to make sure you have everything you need: bit.ly/2DGSzu3

Thanks for the vid but why oh why would you tell someone to cut their factory wire harness vS tapping into them like how you did the power/ground?

Because you have to cut the speaker wires to put the amp in-line. If you just tapped in to those wires, you wouldnt be able to connect the speaker outputs back to the speaker wires on other side.

Yes, you should definitely get some improvement if you switch the subs to the rear channels, though even better would be running a line out converter for all 4 channels, like this one: www.crutchfield.com/I-rYALc384/p_575RFHLC4/Rockford-Fosgate-RF-HLC4.html

If your factory radio has a minimum of 15A, you do not have to use a separate power and ground, although we do still typically recommend using the additional wiring to be on the safe side.

The power wire can be connected to the car's fuse box or directly to the battery. The amp is protected by a 15-amp ATM mini blade fuse. If wiring directly to the battery, install an in-line fuse (15-amp minimum) no more than 18" from the battery terminal and be sure to ground the amp as well.

Thanks for that info, Joe! While we have not been able to fully research this BMW model, it does look like there is a factory amplifier in both the 09 BMW E89 Z4 with or without a speaker in the center dash. The Alpine KTP-445U amplifier is not compatible with a vehicle that has an active factory amp. You would need to bypass your factory amp in order to install the KTP-445U amp.

SO, the tweeters can possibly be connected with the front doors. However the sub will need its own monoblock amplifier channel. That power pack will not power it.

We are not sure how much help we can be as we do not recognize the vehicle you listed. It may help us with identifying it to know the year, make, and model of your vehicle?

We are not able to research the Mitsubishi ASX's and don't have any information on them. We are only able to research vehicles distributed in the U.S. We won't know if there is an adapter made specifically for it, but you should at the very least be able to use a universal line output converter with the stock radio to create preamp outputs for connecting an aftermarket amp. We recommend checking with a local installer for vehicle specific parts for connecting an amp.

Glad you enjoyed the video Jeff. Adding the PowerPack amp would be a nice boost to your front and rear speakers but wouldn't affect the subs. Have you replaced the factory speaker?

JR You covered the aftermarket radio to the Alpine amp, but dropped the ball on hooking the Alpine amp up to the speakers.

You may want to have someone at Crutchfield review your RU-vid videos for continuity prior to releasing them to the public.

That’s a pretty great observation Thomas. I did cover how to connect the speaker outputs of the Alpine amp to the factory speaker wire as a part of installing this amp with a factory radio (speaker level inputs), but I did not make it clear that the process is basically the same thing (cut the factory wire, outputs from the amp go to the factory wires out to all the speakers) when using the Power Pack with an aftermarket radio (RCA inputs). We've updated the description of the video with this information to hopefully make things a bit clearer. Thanks for the comment. - JR

@thomasevans4092 4 года назад

@@crutchfield JR Thanks for the followup. The next question is regarding to new speakers and wiring as opposed to existing stock products. The question here is wire size, as the speakers supply lead wires that appear to be about 20-22 awg. The aftermarket speaker wire I have come across is 16-18 awg or larger speaker wire. Any drawbacks in splicing the 20-22 from the speaker to 16-18 awg for routing from the amp to speaker, then connecting directly to the speaker? The vehicle is a 81 Chevy c-10 Stepside pickup restoration - and if you have clarification regarding the orange/white wire listed for illumination purposes regarding what this wire splices to for power, it would be very helpful. Neither the Alpine nor the Pioneer DEH-X8800BHS radio instructions clarify the source - key or direct 12 volt, etc. Thanks in advance

@crutchfield 4 года назад

I do not expect any issues to occur from connecting those two wire gauges to carry the output from this amp to the speakers. I've also looked at a few pictures we have of this dash and feel like you should be able to install the Alpine in it and may not even need to worry about extending the stock wiring to connect to this amp. The illumination wire is used to automatically dim the receiver's display when the headlights are turned on so it needs to be connected to something that become hot when the lights are on. I recommend consulting technical support for help with the install and to make sure you use the correct wire in the vehicle.
