Customer service was not great. From date of order it took over 3 months to receive. This was only after having to send a few emails. The "everything you need kit" does not include the razor or roller that you need to install the sound materials to doors. This apparently needs to be ordered and paid separately. The kit includes custom made sound blocks. If you have a f150 lightning, you will only have enough to do the front doors. If you find this out after you have installed, you will have to buy more from SGS. They do not include enough to complete the rear doors as I have found.
The install took me by myself 3 full days to complete, minus rear door speakers which I held on for the missing sound blocks but decided I did not want to spend any more additional money on this kit. I would suggest having some previous stereo install experience if doing on your own.
The kit does have some "glitches" as I would call it with the ford interface. Warning chimes do not work anymore, or sometimes do and sometimes don't. The sound when the system auto switches from phone call back to stereo sometimes blasting which is startling especially to our dogs.
Sound is good. Given the spacing restrictions with the stealth kit, I feel it is the best sound that can be achieved with this senario. If you go into the purchase understanding the factory system (b&0 in my case) isn't that bad, and that the low end base just isn't going to happen with the smaller woofers, then it really does sound good for what it is. I wouldn't go thru the labor or the cost again for this system, but do not completely regret it. It does sound good overall.
SGS should include everything truely needed and better customer service. Allso offering the sound deadening kits pre cut for the vehicle would of helped with our install and im sure others in the future.
