Alpins SPS-510 Speakers
2003 Jeep Wrangler
Crutchfield Customer Review (What's this?)
These are great speakers for the size, and are a big improvement over thirteen year old factory speakers. I received everything I needed from Crutchfield to do the installation, and it took me maybe thirty minutes from start to finish. I have yet to replace the rear speakers and the head unit, but I will definitely be ordering them soon.
Pros: Great sound and very clear, easy to install.
Cons: Maybe a little better bass response, but that is about it.
