A: If you are okay with using, an amplifier that’s not alpine, the phoenix gold GX800.4 delivers 125watt x4 @4 ohms, and paired with the R2-S65 and a set of alpine R2 S65C you setup will sound amazing! The higher power output also means that the amp will have better control over the R2’s (I’m running this setup in my own car)

These speakers were installed as replacements for the stock Jeep Wrangler speakers in my Daughters vehicle. I knew Alpine speakers were great but was absolutely amazed at how significant of a difference these specific speakers made! They hit highs and lows the stock Jeep system could not even come close to achieving. The sound on her factory system came alive. What was even better is that the speakers come with the adapters necessary to install the speakers in the roof mount system. It took approximately 30 minutes per speaker to install. The only thing I would recommend if you are installing in any vehicle is to make sure you have the connector adapter for the plugs. Great sounding speakers that improved the sound quality of the stereo and easy installation! Two thumbs up to Alpine and Best Buy for a great product!

Perfect fit for the Jaguar XKR! The car originally came with Alpine speakers, so I wanted to stick with the same brand for the upgrade, and these were a perfect match. Pros: Sound quality. Design. Build quality. Ease of installation. Packeting. Cons: None.

I recently installed the 6.5-inch Alpine speakers in my truck, and they’re phenomenal! Crystal-clear highs, rich mids, and surprisingly deep bass for their size. Easy to install, durable build, and they pair perfectly with my amp. Best audio upgrade I’ve made—worth every penny! Five stars, hands down!
