About the RetroSound R-TB8

Add speakers where there were none
Pardon the pun, but you should think outside the box when it comes to applications for RetroSound's R-TB8 full-range speaker boxes. Got a pickup truck with limited space behind the seats? Maybe you're driving a fleet or work van with no speakers at all (the horror!)? Or perhaps you have a hatchback or an SUV that needs a bigger sound. Pair an amplifier up with these speaker boxes, and your vehicle has an instant big-time audio upgrade. Each of the boxes includes an efficient 8" paper woofer for solid bass and midrange, while the silk dome tweeters deliver smooth highs. Top-mounted ports give you some placement and mounting flexibility, while still allowing the air to move freely.
The nitty gritty
The R-TB8 boxes handle 175 watts RMS each, so you'll want to consider an amplifier to deliver the power to get these workhorses going. Heck, even if you don't have a car stereo, you could use a car amplifier equipped with Bluetooth® to use your smartphone as your music source and volume control. The durable carpet and attached grille on each box will protect them from damage.

Just what my 1990 Chevy Silverado needed. They fit behind the seat in place of that car jack holder and have good sound paired with the Kicker 4 channel 8 gauge amplifier.
