I recently bought a 2008 IS 250 and I want to add an aftermarket subwoofer. I want to put all JL audio products in it and I called a Lexus referred local audio shop. They told me I wouldn't need any equalizers or sound controllers just a few adapters. Since everyone on this forum knows more about Lexus' then they do, I thought I'd ask around here. I searched around the forum but was unsuccessful in finding the answer to my question.

 

try the audio section.........

I don't really know what you want answered. Are you planning to put in 1 or 2 subs? what size? are you going to upgrade and amp the component speakers?


I personally just kept my component speakers and just tapped into the factory amplifier under the plastic cover in the trunk. BTW I have a 12' Alpine type R, and it sounds SWEEEEEEET!

 

I plan on putting a JL 13w6v2 subwoofer in the trunk with the JL 500/1v2 amplifier. I'm going to leave the factory component speakers for now because they have enough mid and high range for what I like. I just want more bass but keep the original head unit. I was reading on JL's website about there CleanSweep® CL441-dsp for the OEM interface but I don't know if I need this or not. It sounds like it would equal out the frequencies with the aftermarket sub but I don't know if the OEM head unit will do that or not.

Thanks for the link. Much appriciated!

 

with the normal 14 speakers does anyone notice them all working when the "psel" is on all speakers? if i switch to driver/front/rear i notice them work seperately. when i have it set to all speakers it seem like only the speakers in the front is on. anyone else have this issue?
