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.
The KTP-445U will work with just about any car stereo, but it's not a plug-and-play installation — you'll have to wire it into your system. If your car receiver's power circuit is protected by a 15-amp or larger fuse (check your fuse box or owner's manual), you can tap into it to power your KTP-445U. Otherwise, you'll have to run a power wire to the battery. Be sure to add a 15-amp inline fuse as close to the battery as possible.
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.
Important Note: The KTP-445U Power Pack won't work in a system with an active factory amplifier. You'll have to bypass the factory amp if you want to upgrade your power with the KTP-445U, and we don't recommend using this Alpine amp to replace a factory amp with more than 4 channels.
