If i purchase 4 Alpine S, 6.5 speakers (2018 Ford Escape); what would be the benefit of also buying an amp - is it worth it - and which amp would you recommend for those speakers?

I don't know anything about car stereo equipment, But those guys are great

I can tell you one thing and you'd be doing yourself a favor. Find a different place to buy from like Best Buy. High End Stereo is a bunch of hacks and thieves. I don't say bad things about anybody without a reason. I wish I never let them touch my car.

Hello Would give you more output and can go with an alpine amp we have many instock to choose from price starting $199 and up
