Re: Harman Upgrade
All SRT's have the same head unit, I think its a valid question asking whether to pay for the HK audio upgrade or install speakers and amps for that price, I vote for the HK audio, I made sure my car had it (it was a deal breaker for me), I was expecting powerful, what I got exceeded my expectations, meaty bass, no distortion when the music is played loud, I had the bass setting turned all the way up for the first day, now its back to its original setting (half way), the idea of trying to integrate anything with this 8.4 HU is very frightening to me, I haven't seen threads any threads discussing it, which leads me to believe its not being done, you could ultimately get the base system hoping to upgrade and getting stuck with it because it can't be done, go for the HK audio, it will help your resale value, and you wont have to worry about warranty voids by playing with your car's electronics and wiring while trying to go for an after market system.
