Great Value

I installed the Alpine SPS-406 model speakers in my girlfriends truck and they sound great. The sound quality is awesome, there is a hint of bass, but a good overall sound. The speakers look nice and clean, and don't look just thrown into the spaces. I am pleased with this purchase and recommend them

Excellent Deal!

Received the speakers quickly and installed them in a classic Ford Mach 1. Speakers sound pretty good, could use more base but I think that is because they're only being powered off a sony deck. Overall, very happy with my purchase.

type s 4x6s

These speakers perform really well considering their price plus they fit in the doors of my cavalier perfectly with the plastic baffles provided. They rattle my doors with only my deck for power. First time I bought Alpine and I must say that I am impressed. You can't go wrong with these.

not a good speaker at all

Bought the alpine sps-406 from Sonic. Shipping was very fast. I installed them the very next day. The speakers sounded okay but after 10 hrs of playing trying to break them in, i raised up the volume and they sounded horrible. My stock speakers sounded way better than these alpines. I don't understand the big hype on these speakers. I don't get why so many good reviews. I should have saved my money. Good thing i didn't buy them for 69.99 or i would have been mad. The only good thing about the speakers is the look and the design.

Low price and easy installation

I bought these for my 2000 Olds Alero and they were easy to install and sound great!

OK Value

Sound OK, can't handle much power and distort rather easily, but sound great at lower power/volumes. Small speaker so what do you expect.

Amazing Sound Quality

I installed these in the dash of my 02 blazer and even with 2 JLw6 12s in the back I can still hear my music with great clarity and they aren't even amplified. I would definitely suggest them to a friend!

great speaker and great sound,

These speakers are great for the price, I've had them for a few months now, I've had absolutely no problems with them, which Alpine is a great brand anyways, but if your looking for good sound for a decent price. I really recommend these.
