My order was ship very quick and was protected very well

The only problem I had at all was the speakers I wanted weren't in stock but other than that great experience honestly and highly recommended for ordering and definately best deals I've found. I've done audio equipment hook ups in the past for my own vehicles and never this smooth.

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.
