Ordered twice from this company. Both times, shipping was fast and arrived before expected. First order had a defective product but was replaced without hesitation. Will definitely do business again in the future and I recommend this company for anyone looking for hard to beat prices and customer service. A+

They had a wide variety to choose from, and the best part was that it wasn't hella expensive like crutchfield. I'm getting all my car audio from deff audio from this day forward.

Ordered a speaker box for my ford F150 and a subwoofer speaker. The first speaker box got damaged on delivery and was replaced after they recieved the damaged merchandise. I'm happy with the new speaker box they sent me and ordered a subwoofer speaker that will fit the speaker box I have. Even the guys at the best buy where I had it installed asked me where I got the speaker box from.
