Scosche MA03B / MA03 Review

I've replaced 2 radios in my car and some for my friends' cars and I always bought a harness for each install. It saves so much time trying to figure out which wire is which while inside the car. And it's so much harder to solder the wires while in the car. I always wire the harness to the one that come with the radio and it'll make it plug and play.

I recommend anybody doing a radio install buy this harness. The time saved is well worth the 10 bucks. Good thing this came free with my radio. Thank you Sonic Electronix!!

Great great radio!

I really enjoy this radio. Ive had it for over 6 months now and Ive had no problems with it. It plays great music. I like that i can sync my iphone to it and play music right from my phone. Thats what i was looking for and I am very pleased with my purchase. It has a great display and I like that it even shows the music from my iphone.

Good Buy, very good product

Very good, saves a lot of cutting and splicing of wires. I found using this to install the Pioneer DEH 6300 UB deck in My Mazda 3 to be very easy.
