I have a few questions regarding my Lexus IS300 F Sport audio system. To preface, I do NOT have the Mark Levenstein audio package. With that being said I do not know much about what speakers are in my 2016 Lexus IS. I know subjectively they sound pretty good. However, I have a set of 4 Alpine Speakers and 2 Alpine tweeters from my old vehicle. I have (2) SPS-610's, (2) SPS-610C's, and (2) SS-10TW tweeters. With that being said here are my two questions:

1) Would the alpine speakers that I mentioned above be an upgrade worth installing, clipping the oem speaker lines and installing the alpine speakers?

2) I know when I ran the alpine speakers in my old ****box I needed an additional internal amp. However, I assume that the OEM system has an internal amp already. Is this a fair assumption? That way if I do install the alpine speakers I wont need an internal amplifier?

Sidenote: I have an old kicker 10" sub that I may or may not install... if I do, I have an amp that I bought for that.

 

Anybody have a chance to give some input on this?

 

The car has it's own amp that powers the speakers and sub which I believe is a below average amp. I think even if you were to plug your speakers in, it wouldn't sound good. The speaker system in the Lexus (IS model) are atrocious. My family's 2012/2013 Camry sounds 10x better. If you want better sound for your Alpine speakers, you would probably want to upgrade the amp... I just installed a 12" subwoofer (with it's own amp) and I am satisfied with the sound.

 

Yeah it really is pretty damn bad! lmao... do you know where the amp is located? So theoretically if I installed the speakers and swapped out the amp in place I wouldnt have to re-wire anything except for the amp?

 

In the trunk, under a floor panel, behind the right rear wheel.
