Any thought on my proposed audio build for my 2020 tacoma?

Helix g five amp

Addison bit 10

hertz MPK PRO 6.5 components up front ACTIVE

hertz MPK PRO 6.5 coaxial for rears

Mr. Marv 10" subwoofer with JL Audio in custom sub box

stock head unit

 

Any specific reason you want to stick with the stock head unit? It has no apple carplay or android auto (assuming you still have the 2016).

 

The title says for 2020 tacoma

 

Duh. I need coffee before responding.

 

Looks like your planning to use the amp to run just the front speakers and the sub right? If so, save your self the money and dont even bother getting new rear speakers.
The factory headunit plays so low on the rear speakers that upgrading them will do nothing with a upgrade.

If you were planning to amp the rear speakers, then I would say to upgrade them.

 

I'd be ditchin' the rears too. You really need processing if you're going to use them - and do it right which means more amp channels. The Bit 10 might be capable of making up for the time difference you'd need to compensate for with factory power...dunno. Its latency isn't that bad, but it does exist...on the order of 10ms or sommat. But in a SQ setup, and I'd suspect that's the goal considering the gear, you'll usually want to bandwidth limit the rear channels at least. And maybe have another preset for rear passengers if the Bit 10 does that. And probably moar power. If you are going to limit bandwidth to the rear, probably no need for coax.
