JL Audio RD900/5

Price $660
JL Audio's RD900/5 5-channel amplifier packs a punch by delivering 70 watts RMS to each of your car's front and rear speakers, while also providing up to 500 watts RMS to a subwoofer. For more intense audio needs, you can switch the RD900/5 to 3-channel mode. In this setup, you can power a pair of high-performance speakers with 200 watts each, while still sending a powerful 500 watts to your subwoofer. To add convenience, an optional wired remote allows you to adjust the subwoofer's volume directly from your front seat, giving you full control over your audio experience.

This was the 7th vehicle I’ve taken to CarTunes in Allen Park for window tint. As with the other six… they did a great job again! Quality work, great price, friendly people.

They built me a custom sounds system from top to bottom and explained to me about what to expect from my system. All of the staff was very helpful.
