How to Install Aftermarket Speakers | Lexus IS300

[@Rx7nator]

Quick question. Where exactly did you ground your rear speakers? UPDATE: I couldn't find a grounding point that didn't have a alternator whine while simultaneously making the speakers get super hot and putting the head unit into shutdown mode. So I just wired the rears into the factory amp bypass harness and ran the wires down the bottom of the door sills and right up to the speakers. Now they sound absolutely fantastic. Rear Speakers: JBL GTO 939's Head unit: JVC KW-V25BT

[@philthemidgits4819]

For the rear speakers in the factory system the reason why you see 2 different sets of wires is that factory system along with speaker has a speaker and woofer in one if you are using mid-bass speakers in the rear you can use red and black but if you want full range audio use that blue wire as your positive and the grey as the negative!!!

[@dylanferris5108]

Hello about to cut mine and wire, is it a blue and great wire for both the LR and RR?

[@robsnizzle7]

I bought a component set (6x9 infinity kappa) and used the cross over.... I used the RED/BLACK wires an negated the OTHER 2 WHICH ARE HIGH FREQUENCY.... THE CROSS OVER DOES THE TRICK AND I GET HELLA BASS in the 6x9's and CRISP highs in the tweeters (which are mounted high on the rear side panels. The reason this dudes stereo sounds SUPER HIGH is THE REARS ARE GETTING "NO LOW FREQUENCY".....

Really loved this video. Changed my factory radio about 2 months ago. Blew my front door speakers a few days later lol. So I definitely needed this video to help me change out my factory speakers.

Glad i was able to help!

I replaced the back speaker in my car only to find out that the Tweeter was bad on each one in the back on the metal plate shaped like a Chipotle rice bowl take a pair of Cutters and cut the little speaker out and make a circle there on the metal plate if you have a wrecked Mustang GT like me I took the two tweeters out of the door screw them over the hole metal plate or bucket that whole piece separates from the speaker itself it can be removed by hand and replaced with glue I drove a little hole through the plastic and ran the new speaker wire through that and reattached it to the rest of the system and it works fine the 6 - 9 speaker was good my car sounds just fine without buying two new rear speakers just replace the 2-in Twitter in that metal bucket on top easier than you think the fabric that was on top of the metal plate I reglued that and put everything back together you can't tell that anything was replaced other than the sound is better here's my advice to you if you like fixing things find two tweeters with screw holes on each side so you can attach them to the metal or like me use duct tape and glue cuz you'll never see it again it's covered up by a speaker cover

[@oruisuu9131]

So no need for an extra metra connector for the rear ? Correct I ordered 2 thinking I would need it lol

[@ALASBEATZ]

I have a whining noise from read kicker speakers every time I accelerate? I have a good ground and all. What can be the issue?

[@DavidPerez-ku5rx]

I have this issue too and getting a popping sound

[@TClipz1]

Its not a good ground is why its whining

@@DavidPerez-ku5rxneed a better ground, someone else commented how to fix it near the top of the comment section

[@MrRick0920]

2005 IS300. I used Metra harness and front speakers were good. Had to run speaker wire to the rear and just come straight from the head unit for the rears.

[@lexusluger3002]

Solid video. I used this for my install last night

[@williamhernandez3863]

Nice info.. Thanks.. Are you ever got to install a pioneer or 1 inch tweeter ? I just did a component sistwm but the tweeter. Wont fit. Oh also if you remove the oem tweeter it will not soumd you have to still connect the cable. Thags what i did. Cut it out but the cable still there so it works

[@LyeraTech2000]

BROO VACUUM UNDER THAT SEAT WHILE YOU GOT IT OUT PLEASE. GOOD VIDEO INFO BY THE WAY.

[@anthonybruno2147]

love the car i got one in red thanks for the video

[@johnlea553]

What was the speaker spacer you used for the front speakers? Or did the kickers come with that mount?

[@finallimit4780]

It was automatically included at checkout on Crutchfield.com. It's a Metra adapter.

[@benjaminkornienko3447]

Sup man, nice vid. However, got some problems with wiring. Connected the positive to the red one, and the black to the bolt, no sound. Any guesses what it can be?

[@norcalnights]

Did you fix this yet. Solved this on my car.

[@deathrejects]

@@norcalnights what did you do to solve it I grounded it but isn’t working it was last night I need a solid ground wiring fix

[@michaeldeihl5697]

What was the fix? I have the same issue

[@hawaiibruv4333]

Where exactly did you put the rear speaker ground to ? The spots I had them in always have had a whine to them , then after a few minutes the heat unit would say miswiring

[@as7792]

Grind/sand paint and ground. Doesn’t matter location. Check your wiring again

[@HonestyHz]

Did you fix your issue with the whining? I’m having the same issue and have sanded my ground location pretty well.

[@hawaiibruv4333]

@@HonestyHz sorry for the late reply, but I ended up hooking up a 4 channel amp. Everything I did still ended up with a whining sound. If getting a amp wired is a issue then I would suggest wiring new wires directly from the head unit to the speakers.

[@gelatoconnoisseur5389]

Why not just order the wiring harness instead of doing that? I have a gs300 and I put kicker 6.5 in the front and rear doors and they sound great

[@Donaldtrummp]

Sweet vid Btw all the wattage and ohms don't really matter to you unless you're running out to a aftermarket amp as long as you have a solid brand you're good to go kicker is more than solid & thanks for the tutorial I'm going to be adding a third 6x9 in the back window with a 6x9 behind the armrest total 4 -6x9

[@THEFHEAD1]

Did you have any signal interference? I can’t seem to get that noise to go away while the car is running.

[@finallimit4780]

If youre talking about that hum, its most likely ground/power issue. Sometimes grounded in a specific part of the chassis will cause a hum. But id say to purchase one of those filters that is wired with your power wire/ground wire. It takes out those noisy imperfections. I was going to do the same to mine in the future.

[@elduve4112]

Okay I know it may be a little bit of a non worry but I really don’t want to ground to a bolt. I feel like that would cause a fire.

[@robsnizzle7]

Not sure if you sound checked your rears but your not getting the FULL RANGE coming from your 6x9's this is due to the stock lexus speakers being an actual component unit which is why the rear plug is a 4 prong black/red (lows) the other two are wired to your highs (tweeters) I know for a fact because I bought 2 way 6x9's for my 05 and didn't get the full range, talked to a stereo installer and you have to bypass the STOCK AMP to get the full range for those type of speakers you've installed "OR" as I did I purchased an ACTUAL COMPONENET SET to get the full range. So my 6x9 woofer went to stock location, and the tweeter i installed into my rear doors.... sounds better anyways.

[@ewfabian]

What brand ACTUAL COMPONENT SET speakers did u get

[@HonestyHz]

He did bypass the stock amp tho lol

[@robsnizzle7]

@@ewfabian myself? I bought a set of infinity reference 6x9's (which I used the black an red wires for the 6x9 woofers), I used the cross over it came with for my woofers to eliminate any high frequency and used the wiring for the highs off the stock plug to the tweeters.

[@Papicodone]

@@robsnizzle7if I’m stock amp what setup should I go with component speaker for just the rear or do all speakers need to be component?

[@robsnizzle7]

The fronts are already set up in a COMPONENT configuration, if you ACTUALLY LOOK AT the REAR SPEAKERS they're SEPERATE UNITS. THAT'S WHY THERES 4 WIRES. I BOUGHT THE "INIFNITY KAPPA" series ($165 I believe) component set used the "BLACK N RED" wires to THE CROSS-OVER PROVIDED with the speaker set. I kept the STOCK CAR AMP TOO... I'm also running an after market deck.... which you'll need the TYTO1 (I BELIEVE that's correct) unit.

[@abdullahcfix]

Yo I bought the same mounting plate from amazon and the screws holding the speaker to the plate are touching the rear deck when i try to lower the speaker into place. Did you encounter this issue and if you did how did you get past it? Thanks.

[@mrpaiute9013]

Did you use the screws that came with the plate, or the screws that came with the speakers? The screws supplied with the plate adapters are ideal and are flush to the bottom of the plate adapters

[@abdullahcfix]

@@mrpaiute9013 None of mine were flush, so I ended up going to home depot and got machine screws with small nuts that were pretty much flush and it seems to have worked.

[@GlassNThings]

Installed a double din but the stock rear deck don’t get any sound? I rechecked my wires and they were all good. What could be the problem?

[@finallimit4780]

Bypassing the factory amp possibly? Bare metal ground? Maybe the speakers in the rear that you have?

[@terry6ster]

Great job u could show us how to unplug all plastics but wideo superlike!

[@hackerdeedline]

Hi! I enjoyed a lot your video! I would love if you explain me how exactly you wired the rear factory connector to the speakers because I did as you said in the video but it doesn’t work. Thank you so much

[@finallimit4780]

I cut the wiring harness and brought the whole harness into my room so i can wire things up. I then wired the positive side of the speaker to the Red wire (or whatever wire on your harness that gets voltage as your radio is on). Lastly, i wired the negative side of the speaker to my metal rear deck for my ground (has to be bare metal). My speakers didnt work either when i first tried them on, but eventually after messing around with power and ground, it worked. Keep me updated!

[@hackerdeedline]

Thank you for your help. It worked :)

[@ewfabian]

If someone was to use an aftermarket harness for the rear, what harness would they go with? Like part number wise and brand

[@mrpaiute9013]

Geez, I've only seen the front door harness, not the rear. Like the guy in video, I ended up using existing plug, you only need the red wire, the harness doesn't offer a ground, which is probably why the rear aftermarket harness isn't marketed

[@ewfabian]

@@mrpaiute9013 I used the stock harness too and ran the negative from the speaker to bare metal but I get this weird noise that gets louder when i press on the gas, also the weirdest thing is that after maybe 20 minutes of playing music, the back speakers stop working and everything sounds staticky idk, i need help lol

[@finallimit4780]

Possibly connection issues near the amp? Either from the radio to the amp may have wiring issues or the amp to all the speakers may have wiring issues. Maybe see if radio is even sending signals? Unless youve bypassed the amp like i did. My set up is from the head unit straight to the speakers. No amp at all for me.

[@josedanganan]

Help! Same issue. Did you ever figure it out?

[@4doorsupra153]

curious as to what's the purpose of bypassing the factory amp?

[@finallimit4780]

More control of sound. Better output of sound. Not so much that the factory amp can put out. Especially now that its almost a 20 year old car

[@bigheadbran1146]

Literally got the same exact setup besides head unit, I tried wiring both positive and negative to the rear speaker with the oem harness and i get 0 sound. Do I really need to wire to ground?

[@lexusluger3002]

Yes

[@ilgwent8061]
