Alpine KTA-450

4CH Power Pack Amplifier

The next generation of Power Pack is here!

The compact Alpine KTA-450 Power Pack Amplifier utilises Alpine’s exclusive DPP technology for a big power boost in a small space.

 

Alpine introduces the remarkable Alpine KTA-450 to their popular Power Pack amplifier range that takes system expansion and power performance to new heights. Equipped with Alpine’s exclusive DPP (Dynamic Peak Power) technology that produces an impressive 400 watts ensures a solid boost of power during music peak transients and high output when it counts.

AWARD-WINNING POWER STACK COMPATIBILITY

The Alpine KTA-450 can mount behind select Alpine 2-DIN mech-less head units, like the Alpine iLX-W650E, using the included bracket. The Alpine KTA-450’s recessed harness receptacle allows the wiring to fold between it and the head unit so both products fit in a standard 2-DIN space.
This PowerStack design is a 2019 CES Innovation Awards winner and makes the duo one of the most powerful 2-DIN radios available.

What's more, the Alpine KTA-450 Power Pack amplifier perfectly pairs with the Alpine iLX-W650E 7” Capacitive Touch Screen AV receiver (sold separately). By utilising the ultra-shallow chassis design of the head unit the amplifier mounts seamlessly onto the back of the chassis. This innovative space-saving design delivers incredible power output and dynamic sound—making the PowerStack duo an industry first and honoured with the prestigious 2019 CES Innovation award.

PowerStack Ready

Achieve dynamic power by pairing the Alpine KTA-450 with the Alpine iLX-W650E audio-visual receiver. This powerful duo is the first of its kind and was crowned with the 2019 Honoree CES Innovation Award for its unique concept.

Dynamic Peak Power

Featuring Alpine’s exclusive Dynamic Peak Power (DPP) technology uses a dynamic power supply design that delivers bursts of power during rigorous musical passages, enhancing the dynamic range at high music volumes.

COMPACT SIZE FOR DISCRETE INSTALLATION APPLICATIONS

The Alpine KTA-450 measures just 89mm (7”) W x 36mm (3.5”) H x  181mm (1.25”) D.  For vehicles that do not have the space for a traditional amplifier, the Alpine KTA-450’s small size allows it to be tucked away in hidden areas such as in the glove box or behind the radio.
It could even be used in a motorcycle’s saddlebag or on a boat.

EXCLUSIVE AMPLIFIER TECHNOLOGY, DYNAMIC PEAK POWER (DPP)

The Alpine KTA-450 features Alpine’s exclusive Dynamic Peak Power (DPP). DPP intelligently adjusts the gain to adapt to musical needs. DPP prevents the Alpine KTA-450 from clipping by supplying up to double the power for sudden, dynamic sounds.
DPP ensures music sounds the way it should at high volumes and boosts the KTA-450 to 400 watts DPP, doubling its power without increasing its size.

SIMPLE INSTALLATION FOR USE WITH ANY HEAD-UNIT

Due to the efficient power needs of the DPP technology, the Alpine KTA-450 does not require a new power supply wire at the battery, so installation is fast using the supplied radio power wires. In addition, the Alpine KTA-450 uses a 22-pin power harness with a recessed design on one side, so the cables can be tucked in for a cleaner, less-bulky installation.
