This product does not meet UK legal requirements for petrol storage containers Review: Adds bite and depth - Alpine head units have a built in amplifier but this provides the missing depth to the music and is an easy plug and play fit. It is small but don't agree that it will fit behind the radio, certainly not in a BMW e30 where dash space is limited. You can tell the amp is working by the improved sound quality as there is no other indication like a light to show it is on. All in all, a very handy little amp which can be discreetly hidden and it delivers.. Review: Easy if your updating your headunit. - Easy to install if your swapping your 'Stereo' system and effectively ups your system but you may have to update your speakers if you want to use at max volume. ## Features - 100Watts Power - Plug and Play Installation - High/Low Gain Switch - Compact Size - Included components: car amplifier ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00DL0N7TC | | Best Sellers Rank | 61,690 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 33 in Car Multichannel Amplifiers | | Brand | Alpine | | Customer Reviews | 4.4 out of 5 stars 129 Reviews | | Global Trade Identification Number | 04958043543441 | | Included Components | Car Amplifier | | Item Dimensions | 20 x 20 x 20 centimetres | | Item Type Name | KTP-445 Head Unit In Line Power Amplifier | | Item Weight | 1 Kilograms | | Item dimensions L x W x H | 20 x 20 x 20 centimetres | | Manufacturer | Alpine | | Manufacturer Part Number | KTP-445A | | Material | Electronic Components | | Minimum Supply Voltage | 12.4 Volts | | Minimum supply voltage | 12.4 Volts | | Model Number | KTP-445A | | Mounting Type | Freestanding Mount | | Mounting type | Freestanding Mount | | Number of Channels | 4 | | Output Power | 45 Watts | | Package Type Name | Box | | Specification Met | CEA-2006 | | Voltage | 15 Volts | ## Product Details - **Item dimensions L x W x H:** 20 x 20 x 20 centimetres - **Voltage:** 15 Volts - **Manufacturer:** Alpine - **Minimum supply voltage:** 12.4 Volts - **Mounting type:** Freestanding Mount ## Images ![Alpine KTP-445A KTP-445 Head Unit in Line Power Amplifier, Black - Image 1](https://m.media-amazon.com/images/I/51eFi0LWJCL.jpg) ![Alpine KTP-445A KTP-445 Head Unit in Line Power Amplifier, Black - Image 2](https://m.media-amazon.com/images/I/61H7Jgp2siL.jpg) ![Alpine KTP-445A KTP-445 Head Unit in Line Power Amplifier, Black - Image 3](https://m.media-amazon.com/images/I/41dzOXpyTAL.jpg) ![Alpine KTP-445A KTP-445 Head Unit in Line Power Amplifier, Black - Image 4](https://m.media-amazon.com/images/I/31Dzp0cTS4L.jpg) ![Alpine KTP-445A KTP-445 Head Unit in Line Power Amplifier, Black - Image 5](https://m.media-amazon.com/images/I/31xpx5nvllL.jpg) ## Questions & Answers **Q: Would it work with e46 oem radio** A: no **Q: Will this work with a pioneer mvh-a210bt?** A: No **Q: Do you have to have all channels used if I only have front speakers** A: No. I used this amp in an MR2 roadster with front only speakers. Great amp. **Q: The information is confusing (datasheet is different to tech details), is this a ktp-445a or ktp-445u model?** A: The U version is universal and will connect to most head units. The A version is for Alpine head units and comes with 2 connections that will plug directly into the Alpine head. Tech specs are the same. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Adds bite and depth *by C***4 on 24 July 2020* Alpine head units have a built in amplifier but this provides the missing depth to the music and is an easy plug and play fit.

I''m really impressed with the quality sound of this amp for such a small "brick". I will rate this amp at only 4 stars bcz i had several problems having to do with the power supply from car OEM that comes in line with the head unit, after one week of intense use the OEm fuse blown bcz I am a heavy listener and at high volumes amp needs more power(amps) the 18awg car oem wiring was unable to deliver the minimum 25amps needed for the amp and head unit so voltage drop happen ,after 22volume (from 35) a kinda protection was coming on and volume was automatically dropping at 7level. So what i did I''ve upgrade the constant12v and ground with 12awg from the battery and went to amp iso to connect it(you need to cut old wire and isolate maybe in the future you might solder back). I have to say that i can go over 18volume level bcz is much louder after wire upgrade and no protection coming on at high sound levels. Very very happy with the outcome 😊☺️ small, compact and quality sound. Also if i have to buy it again i will go for the other version ktp445U as you can put proper wiring and also better sound quality. I hope that this review will help others to know the pro and cons for this amp. Also head unit and amp very good combo high quality and Manny functions. I wrote this kind review cuz i was looking for this kind of experience and i didn't find anything hope to help others to enjoy good quality sound. ## Frequently Bought Together - Alpine KTP-445A KTP-445 Head Unit in Line Power Amplifier, Black - Alpine UTE-73BT Mech-Less Digital Media Receiver with Bluetooth® Wireless Technology --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/48472580-alpine-ktp-445a-ktp-445-head-unit-in-line-power](https://www.desertcart.kg/products/48472580-alpine-ktp-445a-ktp-445-head-unit-in-line-power) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-06-03*
