Purchased the entire alpine package. Head unit, amp and speakers. Couldn't be happier with the quality and the sound.

I 've had these Speakers before, this is a Replacement set. Why Change something that's good? All of my Speakers are Kenwoods I wouldn't Change a thing. Excellent!

I would recomend these to anyone
I have em in my 2012 harley davidson street glide.

Can't handle much power. Sounds great at lower volume/power, distorts easily at higher volume/power.

The Alpine SPS-510 I bought is working excellent..
It is just the way I thought it was perfect,
I would recommend other people to buy it,

I recommend these speakers to anyone who wants 5-1/4" speakers. They also sound great paired with just the headunit.

Alpine is the best. Thats all I can say. I recommend.

I bought these to replace the factory speakers in my 92 jeep cherokee and wow are they great. They have a great response for only being they type-s series.
