Well this weekend was an amazing for me and my car. Matt not only fixed all my existing issues from my previous install but also upgraded the speakers, amps, and installed a new BT Audio module.

First the original install. I had it done by a small local shop that was pretty popular with everyone else in the area. That was a big mistake, I told that to take there time and do it right, but that didn't seem to matter much in their small busy shop, though they did take their time. There was an annoying buzz which they could not get rid of every time your turned it on, an obvious grounding issue which they couldn't complacently solve though attempted with ground loop isolation.

When Matt took the system apart and saw the rats nest of wires and connections not even tapped just copper rapped around other copper to make connections it was clear why things weren't working right. The ground issue was because they just grounded everything together but never made the connection to the body. We even found the mic that they told wasn't in the box when I gave it to them and had to order another. In the end I think we removed about 30' of extra cable that was either too long for where it was going or served no purpose at all.

As for the installation portion of the work, these were the items I ordered and had installed.
1. Rockford Fosgate Prime 750 Watt Class D 1 channel Amplifier
2. Alpine PDX-F4 4/3/2 Power Density Digital Amplifier
3. Hertz HSK 165 6.5" 2-way Hi-Energy Component Speaker System HSK165
4. Alpine KCE-400BT-Remote Mount Bluetooth Interface for Selected Alpine Receivers
5. Stinger 17 Foot 4000 Series Professional 4 Channel RCA Interconnects

Already installed & Keeping are
1. INA-W900BT Head Unit
2. 13TW5-3 Sub

Everything went smoothly aside from some minor frustrations at the crappy work that was previously done. Matt does good work, I saw for myself first hand, and I think he knows just about every nook and cranny of the 370z by now.

I am very happy with my audio system now, music sounds like no other car I have had before and all the functionality is there that I want. Some day I may upgrade the head unit to a newer model and I will defiantly return here to do it again because Matt is a real audiophile and takes pride in his work.
