More power, less hassle

Want a simple way to crank up the power of your receiver? Alpine's "Power Pack" amplifier increases your receiver's power output to 45 watts RMS by 4 channels. That's a big jump up from the 7-20 watts per channel typically put out by a car radio, and plenty of power to drive high-performance speakers or keep up with a big subwoofer amplifier. Best of all, this compact amplifier is so efficient you can often run it off the same circuit that powers your receiver. A universal plug lets you feed a signal via RCA outputs or speaker-level wiring.

You can install this compact amp behind most dashboards, but you'll need 4-channel patch cables to connect your car stereo to the amp's preamp inputs. You can also splice into your speaker wiring to get signal to the KTP-445U.

Installation Note: We recommend running a dedicated constant power wire to the battery for optimal performance from this Alpine amp — we offer an inexpensive wiring kit for this installation. This high-powered amp won't work in systems where an outboard factory amplifier is still active.

Works well, easy solution November-28-16
Reviewer: Anonymous person from Marlboro, NJ  
Definitely makes a significant difference. Driving JL C2 690tx (which were asleep with the aftermarket Pioneer HU) and JL C2 350x which were fine without an amp. Was able to fit it behind the stereo


 
Magic in a box! November-20-16
Reviewer: Rick from California  
Love this small amplifier! I needed something to drive my JL C3s and this amp pushes them nicely!  I'm used to the larger 4 channels from the past and this fit in my glove box
