• SPEAKERS: The new entry level 'J' speaker series offer uncompromising quality and sound performance that Alpine is famous for. Featuring a hybrid pearl-mica injection-type cone and air-injected rubber surround, these speakers are not only aesthetically appealing but deliver ultra bass and midrange, plus the balanced titanium dome tweeters ensure highs are crisp and clean.
• AMPLIFIER: The R500X1D's heavy cast aluminum chassis efficiently draws damaging heat away from its internal components, ensuring reliable, long-term play. The amp's built-in sensors keep track of the output current and power supply temperature, ensuring that plunging subwoofer impedances (they change constantly during play) or even a short circuit won't hurt anything.

It includes all of the cables, wires, tubing, ties, grommets and ring terminals that you will need in order to get your new sound system up and running. The car amp install kit works with a wide range of sound systems and car types and it makes the installation process much simpler by conveniently adding all your supplies to one single kit.
