I have a 2007 is 250..basic stereo system with car..
I want to install the system that was in my other vehicle:
2 Alpine Type R SWR-1243D subs
1200W Hifonics Brutus amp
Zenclosures box

I need to know what else I need...
Like..

1)Sound processor called audiobit one or something?
2) Wiring Harness
3)Amp RCA converter?
4) What gauge wiring??

Truck stereos are much easier..never dealt with stock radios before

 

yes you will need a line converter for your rcas...

as for wiring always (and I can't stress this enough) use at least 4awg...make sure your ground is the same awg. If not your not getting full potential of amps and may cause damage due to strain.

any installation is about the same, just take your time and it will all work out.

 

Thanks a ton!!
Would I just google lexus is 250 line converter or will any one do
And im guessing that sound processor is just an extra but doesnt make a significant difference??

 

Tons of information here.

as i had said in the prior thread you made OP. Just need a Lineoutput converter. go to a best buy and say those words. install what they give you.

buy a 4awg amp kit of quality brand. and speaker wire. done.
