I fed the 0 gauge into a 3 way power distribution block to each amp. I ran a 0 gauge power wire from the battery to the rear of the truck and it will fit under the stock plastic covers near the door. There is plenty bass once you add in the cabin gain. I am running an Adire Audio Shiva Mk3 in a 13.5' sealed enclosure. It really sounds great for the money I've put into it. I am running PRV mids for the doors and JBL tweeters in the stock locations.

The amps are easily mounted behind the rear seat. I have 2 Skar Audio 4 Channel Class D mini amps running to the mids and highs and 1 JBL GTR 1001 to power sub. I went with a DSR1 and the harness that keeps all the OEM connections. I've always been into car audio though so I knew I'd get the upgrade bug eventually. I have a 15 Lariat with the Sony and at first the system was alright. I'd go with a Rockford DSR 1 for the Sony system. became common, so I'm not sure how these all interact in a modern system. Sorry if I'm asking something obvious, but I don't have experience installing car audio systems since touch-screens, voice control, DSP, etc. What would you recommend as the best upgrade path to improve the sound and functionality (ideally, without tearing apart the whole vehicle interior and spending a lot of money)? I'm essentially looking to upgrade to something equivalent to the Sony premium system or better. I would probably do the installation myself (I've installed a few basic car stereo systems over the years). I'm not looking for a super-loud system or exaggerated bass - just good, clean sound. I do want to be able to easily access music stored on a memory stick (or something similar). I don't want to compromise my back seat storage area with large subwoofers. I'm assuming that a more powerful amplifier and upgraded speakers would be worthwhile. Unless there is a compelling reason to replace it, I'd prefer to keep the OEM head unit. I don't want to give up any of the factory functionality (Sync, etc.). I've read through this forum, and I see that people do some very significant system upgrades that can take many hours of work and cost well over $1,000. If it had the upgraded Sony system, I'm sure I would be happy with it.

It is pretty loaded, including navigation with an 8' touch-screen, but it has the standard stereo system. I'm looking at buying a 2015 F-150 Lariat Supercrew 4x4.
