I have integrated 2 previous vehicles and did not care for either results. A 2007 Tundra I used a JBL MS8 after the amp and never got it how I wanted. I went active with the crossover and it was not good, did not matter how I tried it was just awful. So went passive and it was better but nowhere near what I was expecting. I ended up pulling the MS8 and cutting a Alpine HU in bellow the OEM radio.
Also had a 2012 Wrangler I used a PAC module after the radio and that unit did not allow any OEM adjustment and I never bought an EQ to make adjustments so I really did not like that either. This will be the first time I have used Optic out; always analog in the past so I'm a little unsure. I need to find a DSP and there are several with Optic in, but I have no experience tuning them. Not sure if there is a user friendly DSP for the DIY? I'm OK paying a shop for the tune if I can't do it. Researching five different DSP's now.
