It would be helpfull when considering speaker upgrades to know exactly what is in the car in the first place. Is there a schematic of the audio system stating speaker sizes, power handling, wattage, capacitors, etc? If not, does anyone have a self made inventory of pertinent information on the stock audio system? Thanks

 

Goux - Look first in the Lexus Q&A section pertaining to audio. Percy & I compiled most of that info & then maybe U might consider shooting Percy a PM because I recall him having a schematic on the non-Nak system a year or so ago. BTW - with the Cajun spelling of Go ( "Goux" ), R U from down here in Louisiana?

 

i had my stock speakers replaced, i looked at the stock speakers and they look like 4's to me. im not sure where you can find the technical data on the stock system.
