Make sure they do a good job , they did mine which was ok but broke the surround for the stereo and i had to wait a few weeks for another one from japan and for them to re do it.
They also squashed my sled out of shape and only put 2 screws in to hold the stereo cage in to the dash which caused loads of rattles.
The reason i went with them was i could not get the empeg to work in my car ,they found the problem (bad earth on the loom).
But i wont be going with them again , and when i fit my tuner i am going to buy another std factory carrier as mine is well bent now.
