Lexus IS250 car stereo budget build sub and amp install! Sundown LCS-12's

[@derrellwilliams2810]

Bless you for this video. Finding info on audio systems for this car is a pain in the ass.

[@anthonyt2796]

Not wrong. Full wiring diagram for 2009/2010 ML system is here, but appears to be likely same for Non ML as well: www.clublexus.com/forums/is-f-2008-2014/942642-2010-mark-levinson-wiring-pin-outs-for-line-out-converter.html

Thank you!

[@Aphraidknot]

Thank you for finally pointing out the actual connectors rather than all the forums stating "Hook up to green and brown wires"... There are fifteen green wires lol! Hooked up Kicker Hs10 with speaker sense and works fine... IS350, Navi, Non ML.

Just installed my sub and couldn't have been any easier thanks to your video. Running a single 10 inch Skar DS2 with their 800 watt amp and custom box. It hits super hard!!! Probably spent around 300 or less! Super happy to be bumpin again.

[@NextLevelCarAudio]

Thanks for feedback. My amp does not do that tho

I also have an alpine for the highs fsx65s in the doors 4 VX35 tweeters , m69c massive audio in the back deck plus sound deadener in the trunk lid, quarter panel & doors great but cheap stuff!

[@jaredlindsay5690]

I have an 09 is 250 and I have everything wired the way you showed in the video, cut wires to crimp on the high/low converter and connected all the right wires. Only difference is that I wired my remote through a switch and then to my cigarette lighter for power to have to option to shut off the aftermarket amp and sub. When the sub/amp is turned off, everything is normal with the sound system, but like 5-10 seconds after the amp powers on I lose audio from all speakers in the car. When I turn the amp back off I get sound from the other speakers again after Bluetooth reconnects from my FM transmitter. Was wondering if you had any idea as to what could be causing this. I did also tape off the wires going to the factory sub separately so nothing would short out. Everything checks out with multimeter except I don’t seem to be getting signal coming through the LOC to go to the amp. Not sure as to why. Thanks for reading

[@killjoyclown]

Will the stock sub still work after doing this

[@dragongogo9]

[@richardhernandez4372]

Sounds hella good i do think you shoulda have removed the top deck factory sub so when the arm rest is closed it acts as a port from the trunk and gives a lil deeper bass

Sounded perfectly good enough for me. People can totally remove it if they wish.

[@jaysonoliveira4752]

So your only power wire going to 800rms amp is that tiny white wire?????? I have a 2014 es350 ML....i want to install my jls. I like the idea of using the white wire for the remote wire, and also tapping into the factory amp for the loc.

[@NextLevelCarAudio]

No sir.... I did not show the power/ground wire install. Sorry! I have a fused 0awg power wire and 0awg ground wire running to the amp. at 9:05 min into the video you can see the blue and red power ground wires ran into the amp.

Speakers and amp from down4sound.com free shipping and no tax. Best prices. The sub enclosure I got from eBay. Just search Lexus is250 subwoofer enclosure. You’ll see them. And finally the LOC to convert your speaker wires into an amp RCA signal. Search LOC on amazon and buy any one you prefer. They are cheap. Then obviously you need an amp wiring kit. You can also find them @ down4sound.com if you want quality. Be careful of the cheap ones on amazon/eBay. I never skimp on my electrical/wiring. Hope that helped.

[@NextLevelCarAudio]

Pull the door speakers to verify wire colors, then match them up back at the factory amp. Use 9v battery test to ensure you got the right wires and polarity. Done

[@djdrama4252]

So by using that output device and cutting the stock sub wires for the stock amp, are you cutting off the stock sub all together as well?

Yes, but you don’t have to. I did not want the stock sub anymore

@@NextLevelCarAudio so what would be the best way to have both going? Would running the output device to same wires shown in the video and also connecting the sub wires (in the correct color order of course) cause any issues “output” wise?

No issues at all. Just leave everything connected from the factory as is. Then tap in the Line output converter to the appropriate wires and your good to go. 😎

[@djdrama4252]

@@NextLevelCarAudio sorry if this is a stupid question but how do you mean “tap in”? Dont you have to cut/take out the stock sub wires from the amp in order to connect to output converter

[@richardmontoya3449]

I have a question. Why didn’t you leave the factory sub connected as well? Does it not have enough signal after you tap into the wires?

[@NextLevelCarAudio]

You could have left it.... but with the two 12’s in the truck it completely washes out the factory sub and don’t even hear it. I also tried leaving it, and bass was a tad louder with it removed. Like a passage for the bass so to speak. Armrest is blocked off by the enclosure, so opening and closing that does nothing.

[@ashtonbarran4652]

When you connect the speaker wire to the amp can you still use the stock sub and run after market amp and run aftermarket sub

[@NextLevelCarAudio]

Absolutely, there are people that do that with no issues.... only reason i removed rear sub is to create a passage between the cabin and trunk to hear the bass a little more.

[@ashtonbarran4652]

NextLevelHummer so when I did it today I wasn’t getting any bass from my sub I did every wire you said so what you think could be the problem??. The amp is getting power and everything the line input is so so idk

[@ashtonbarran4652]

NextLevelHummer I have the 08 model

[@NextLevelCarAudio]

hey man, sorry to hear that. i don't believe there is any differences between the 08 and 11 as far as the stereo is concerned. but don't mark my words on that. could very well be the LOC, if there are gains on the LOC unit, make sure they are all the way up. Then use the gain on the actual amp to dial it in properly. the only other thing is your amp is just not getting any input signal. which means the incorrect speaker wires were tapped into. which may be slightly different from year to year. best thing to do to eliminate that possibility would be to verify the wires/colors from the oem rear sub/speaker to ensure you are tapping into the right ones for your vehicle. let me know if any of that helps. good luck

I see some of the line audio converters are like 50w-80w does that translate meaning that it will only process that many capable watts through the amp or is that something separate like the power it requires to Run on?

[@NextLevelCarAudio]

No, that does not matter. Which model exactly are you talking about

Your fine, that car run any amp no problem

[@axlmcintosh6148]

Once the wires are tapped in, do you reconnect them into the factory amplifier or are they left unplugged? Apologies if that is a dumb question. Thanks in advance!

[@NextLevelCarAudio]

Once you tap into them, disconnect them from the factory amp. Otherwise you are going to get a messed up signal

Great video. Thoughts on adding dynamat to the trunk to help with rattle?

[@NextLevelCarAudio]

Absolutely, definitely helps.

Where can I get that sub box I have a custom one but I have no trunk space ?

[@NextLevelCarAudio]

Can’t find it for sale anymore. Was on eBay. I V searched Lexus is250 subwoofer enclosure. That’s how I found this one

[@brandonjohnson131]

Great video! I just ran across this while looking to upgrade the sub in my own IS. Question, who made the box? It looks to be about 2 cubic ' internal? Thanks in advance!

[@NextLevelCarAudio]

Yeah, I actually snagged it on eBay. Was a prefab. Couple people tried finding but no longer an item for sale :(
