The last stage will be a new head unit. (a massive cost invovled)
Is my logic correct ?
I am not familiar with the Laredo x audio package, is that the same as the alpine package in the overland? That is what my post assumes.
The only problem with adding an amp before a head unit is that an amp will need a line converter to be used with the stock head unit, which is about $130 - $180 depending on how many channels u want to convert. In my example above I used the LC8i which is $180. An after market head unit will not need one of those so it will be wasted money once you ditch the factory HU. But I guess you can always eBay out the LC when you no longer need it.
Starting with new speakers is good, but keep in mind the factory amp outputs discrete channels for the door woofers and the tweeters. That means if you use components up front, the input will be from the door woofers which is most likely already filtered so the new tweeters may not get all the high signals. This is why I plan on summing those two channels with an LC8i. The rear doors should be fine to replace though since there is no separate high tweeter channel.
All indications about the factory sub is that it sucks. The enclosure is plastic. Adding a higher powered subwoofer in there will result in rattles and muffled sound. Best bet is a $600 stealth box or the slim box you were talking about.
If you want to continue using all the non-standard surround speakers with the aftermarket head unit, like the center and rear pillar surrounds, I believe you will need some kind of DSP or something. I am not up on the new head units out there since my plan is to keep the 730n. I also don't think the factory amp would work with an aftermarket HU, if it did then that would make a modular upgrade easier: start with new HU, then you can add front components, amp, rears, and sub at any time. But unfortunately I don't think you can.
