## Description

What we sell? New SoundXtreme 5x7/ 6x8" 3-Way 350 watts coaxial car speakers ceca rated (pair) product highlights: music is a great companion when you’re on the road, but most cars on the lot come equipped with low-quality factory speakers that don't do your favorite tunes justice. If you're a real audiophile, it might be worth swapping out your car's speakers for ones of a higher caliber. And the good news is that you don't have to spend a fortune to do it, either. But before you begin your hunt for a New audio system for your automobile, there are a few things to consider. First should be budget. How much do you want to spend? Other important factors are sound quality, speaker size (DO you want a 6x9 speaker, a 6. 5-Inch speaker or something with a killer bass?), as well as design. To help you make the right decision, we only choose the highest quality speaker such as SoundXtreme SX for you to buy.

Review: Pretty good speakers at a very affordable price - not a lot you can say on this one... I bought these speakers to replace the pilar speakers in the rear part of my van. I was surprised how much better the stereo sounded. These speakers are very inexpensive so my expectations were not very high but they clearly exceeded expectations.
