Hi All, So I'm looking at upgrading the sound system in my base GT. I am not looking for a competition system, but would like something that sounds nice, has at least some power, and maybe even improve the looks of the dash. The options: 1. Use a LOC on the stock HU and add an amp and four new 6.5s (one set of components for the tweeters on the pillars). Of course this means keeping the stock HU, and getting a four channel LOC. If I ever wanted to add a sub I'd need another LOC. Probably the cheapest option. 2. Scosche Dash Kit: and some other Double DIN HU. Of course even those HUs only have about 50w peak power, so probably would still need a small amp, but no LOC and would then have sub outs. However, I'm concerned about the climo control stuff. Has anyone used one of these dash kits? What about the backup cam (I'd be getting a nice HU that would hopefully have this option, like an Alpine)? What about the steering wheel controls? This would be the second most expensive option, and certainly look better than the stock HU. 3. A 4.5 to Sync 3 swap: 2015 Ford Mustang SYNC 3 Upgrade for MyFord Touch Most likely the best looking option, however the HU is still underpowered thus an amp would still be needed. Not sure about any sub outs. Also by far the most expensive. All that said, anyone with any other ideas? What have you done to upgrade the sound system in your base GT?
