The Jeep Wrangler alpine premium Audio system features a total of nine speakers, including two upper dash speakers, two lower dash speakers, two left side soundbar speakers, and two right side soundbar speakers, along with a subwoofer. The subwoofer has four 2 ohm voice coils. It is powered by four channels of the factory Alpine 552 watt, 12 channel amp, with each of the other eight speakers having their dedicated channel. The factory subwoofer receives approximately 184 watts from the combined four channels, and its RMS power handling is likely similar to that amount.
In the factory Alpine system, all speakers are 2 ohms. If you want to upgrade by replacing speakers, make sure to use 2 ohm speakers such as the Kicker 42PSC652, which are compatible with the knee panel and overhead speaker bar. When using METRA connectors, ensure the polarity is correct to avoid reverse polarity issues that can degrade sound quality. If you opt for speakers from sources like Amazon, they are likely 4 ohms, resulting in halved sound output compared to the 2 ohm amp speaker amplifier. An 8-speaker system with a subwoofer can be enhanced by selecting 2 ohm speakers.
The Jeep Wrangler's alpine premium audio system comes with specifications such as 6.5-inch Spt-71 front dash 2-way component speakers and an 8-inch powered subwoofer.
