Question regarding Tacoma jbl system

here's the thing. if you're asking that, i'm genuinely questioning your capabilities, which makes me much more guarded to offer up information.

no offense to you or what you're trying to do, but forcing things to work because "some guy on the internet said i could" has far too many ways to go wrong, and i don't know how much i want to be involved in that.


the existing speaker wire goes from the oem amp location behind the rear seats, via individual runs, to each speaker location.

but that's where the simplicity ends. what you intend to do is going to drastically alter how those existing wires could be utilized. will you be using a DSP? how many amp channels will you have available to use? will there be passive crossovers? where will they mount? will there be coaxial speakers?

the important thing here is to come up with a game plan before diving into it. could the factory wiring be used? sure. but it's only about 18 gauge speaker wiring.

by my estimate, having just a 'simple' head unit, amp and new speakers, you're very likely going to be nearing about $2-3k in equipment costs, especially if you're paying someone else to install them. and you'll want to be pulling trim anyways to install the RCA cables from the head unit to the new amps.

it really comes down to what you want to nickel and dime. if the interior is apart, sound deadening is a really good idea to maximize the performance of the new gear. and once the interior is ripped apart for sound deadening, running the RCA cables, and running all the new power and ground cables for the new amps, really, what's another few wires for new 12 or 14 gauge speaker wire?

 

You are right, I am not the audio guy. I am also not looking for the system of all systems and insisting on every parameter of every component be in perfect harmony. I am very capable of adding new speakers to factory locations using existing wiring and any pigtail adapter needed. One of the comments above made it sound like replacing the wire was required so I am questioning that….And planning!!

I generally stop there as I am not an audio guy. I also don’t want 20 wires running all over the place even if it’s hidden under the carpet. I don’t like that and usually find even the audio guys are very sloppy. I will pay someone to do the head unit and amp. If my sound quality suffers an infinitesimal amount because only 95 watts made it to the speaker instead of 100, I am going to live.
