Do you know the polarity for the front speakers for a 2019 Subaru Impreza base model?

[@jasonheiken6347]

They should make an aftermarket part so you could remove the ashtray and have a smart phone compartment 🧐. Great video!

[@ProvoBeastAudio]

That would be cool!

Hey friend. I got the Metra 70-8112 harness and mine does not have the brown and orange wires like yours has. Did you have to pin those ones in yourself? Thank you

[@bluesky-ud9wg]

Excellent Install!! Very impressed.

Hi, you skipped the part where you cut the giant X off the screen? How did you do this without leaving white marks

[@bryanbarajas681]

how did you end up taking off the x?

I used a small wire flush cutter.

[@brandonallgrim511]

im confused where did you route those two blue wires? it looks like you put the blue with the blue and white wires together just making sure. I also have a aftermarket amp

[@oz6708]

Thank you, much appreciate. Very helpful video.

[@chadw566]

With this upgrade on a nakamichi system, do you have to leave the amp installed? Or can you remove it and run the speakers without the amp?

[@ProvoBeastAudio]

With a bit of rewiring, sure, you can bypass the factory amplifier. We kept it in this vehicle per the customer's request for the time being.

[@osiris.y]

how do you bypass the amp? im asking because my amplifier does not work so i plan on doing that, thanks @@ProvoBeastAudio

[@javieralday7001]

Hello I connected everything and the radio turns out but I have no sound. I have the 6 cd changer in the trunk and used the harness of the plug. besides the purple grey and white wires for the speakers i didnt use the blue/white wire which is for the amp and im using a sony unit. do you have an idea of why it is not working? should i try the other harness or something else?

[@ProvoBeastAudio]

Blue white wire controls the factory amp. Required to be connected to the radio in order to trigger the factory amplifier to turn on.

[@joshhernandez2574]

@@ProvoBeastAudiocan i wire it with red or yellow cause my lexus harness dosent have a blue white wire

[@sodmodwatanabe]

@@joshhernandez2574you can, but be careful, wore it to cable where current exist only when you turn acc otherwise stock amplifier in the trunk will be turned on always

[@michaelsilveira3495]

I have this exact car, same color interior and put the same radio in and you make it look so easy😊 now show us how to replace the LCD read out in the climate control unit with the lightbulbs. I’ve done that it’s not easy. Maybe you have an easier way to do it.

[@stopmotionking241]

The Metra harness is different now. There’s no yellow, no orange, no brown. And my speakers are just making buzzing sounds. I’m so confused cause I follows this exactly as you did it

[@Zerd74]

Where do the RCA cables go? I wasn’t able to see in the video

[@KidFlazh21]

Into the stereo

[@sodmodwatanabe]

Dear @provobeastaudio , please tell why after installing this kit, front and rear speakers work but my original Nakamichi subwoofer not working. Maybe you know what I have to wire additionally to turn it on? Do you know which original connector pins/cables go to subwoofer signal?

[@soursalt5867]

Very helpful. Thank you

[@zenthspike]

Hmm the metra Amazon plug you linked below does not come with orange leads. Why is that?

[@dilippatel3268]

excellent video

[@lelishdepaso1639]

Thanks for the instructions. Got everything working. Only problem is I am getting a noise if the engine is on and noise increases with acceleration. Planing to use ground loop isolator. Which wires do I need to connect?

[@ProvoBeastAudio]

Sure, well it depends on your trim and parts used. If you have the factory amp (like we did) and using the harness adapter with the low-level RCA connections, then this ground loop isolator may help (two orders needed unless you buy a 4 channel): amzn.to/3KfDIYm

[@lelishdepaso1639]

Thank you. I assume this is plug and play and don’t need to ground and solder anything. I would just have to plug the 4 ends to the 2 ground isolators and plug the ends from the isolators to the unit

[@lelishdepaso1639]

@@ProvoBeastAudiothank you for the suggestion, got 2 of them and that did the trick. Sound is as clean as the OEM.

Do they make a radio with climate controls on it for this car?

[@Paranoid-loser]

Hey, I'm wanting to do an aftermarket amp in my sc300, I have the 12disc cd changer and ik the amp is under it, would it be plug and play to install a new amp or would it require a lot of work?

[@KaiPonte]

Any idea what size screws are holding the trim in place?

[@osiris.y]

Quick question what if you’re trying to bypass your amp and use the amp build into the radio can i connect those speaker wires from the radio harness and run them to the speakers itself ?

[@Meezy420]

I did this and it works. I was lazy tho I only wired to subs nothing else but a lot cheaper than buying an amp that’s for sure

[@osiris.y]

@@Meezy420 yeah I ended up doing it and got new apeakers

[@brett7989]

Hi we have the Japanese import 1991 soarer . With the v8. It has this stupid stereo that has the heater stuff in it. If we get rid of the stereo and put one in like u have done we would also have to buy the lexus heater unit like you have which is easy to buy. Would you know if it would be hard to wire the heater unit

[@sodmodwatanabe]

If the heater controls are integrated, you will not be able to control heater. I would just modify stock stereo system

[@adventsociety5382]

How much would this install typically cost. Don’t have the time right now to do myself

[@ProvoBeastAudio]

Parts we used are linked in description for current price. Labor depends on your local shop.

[@PaulNguyen-q7u]

what sc are you working on? Mine is 1999 sc400. on the back of the stock radio there are 4 connectors. and I see is that the male connector from the Metra 70-8112 does not fit to any of them. Can you help.

[@ProvoBeastAudio]

You will need the Metra 70-1761 if the other doesn’t fit.

[@lalito._.01]

I wired everything correctly but still have no sound, maybe i have the rca colors mixed up?

[@ProvoBeastAudio]

No, sounds like you failed to hook up the blue / white amp trigger wire. Your factory amp isn't turning on and consequently have no sound. Hook up that wire in the harness adapter to your new radio's amp or accessory wire, and it should turn on the factory amp.

[@lalito._.01]

@@ProvoBeastAudio turns out it was the amp wire, for whatever reason it was being pushed out of the connector. I had to hard wire it into the factory cable

It's underneath the cd changer in the trunk

Do I need a new amp if I’m having a whining noise ?

I’d recommend to bypass the amp if you have a ground loop issue, or trying using a ground loop isolator.

Hey man wondering if you can shed some light on a situation I’m having in a 2009 Acura TSX while installing my aftermarket radio my constant power cable made some contact and all I heard was the spark and now I have no constant power all fuses are good in the car and under the hood any info would be greatly appreciated thanks in advance

[@ProvoBeastAudio]

Fuse somewhere. There is a fuse box under the hood and in the cabin of the car. Look in both places.

@@ProvoBeastAudio can you do the speakers

[@Mister_Y]

How do I determine if I have an amplified sound system?

[@ProvoBeastAudio]

If you have the 6 CD changer in the trunk l, you have the amplified sound system.

[@Mister_Y]

@@ProvoBeastAudio I do have the 6 disc changer in the trunk but was always uncertain if mine was the amplified system because looking at the factory head units, some are Nakamichi, which as I understand are amplified. My head unit doesn’t display the Nakamichi logo but my vehicle does have the 6 disc changer so some confusion there. Wondering where I would look, if the factory amplifier was mounted in a specific location to determine, assuming it wasn’t built into the head unit.

[@chadw566]

There in an amp mounted directly under the cd changer. The cd changer implies your car is amplified. It's most likely a pioneer amp as the nakamichi systems had it advertised on the center console

[@osiris.y]

its under the cd player @@Mister_Y

[@LostCauseLearners]

did you get whine when the cars running?

[@ProvoBeastAudio]

Nope. If you do, it may be a bad ground, harness, or radio as your culprit

[@Paranoid-loser]

Really would have appreciated it if you would've gone step by step instead of fast forwarding through the complicated parts

[@ProvoBeastAudio]

If you have any issue, just send us a message on Facebook and we can point you in the right direction. When videos are too long, people skip too much missing important info. So trying to find the right length between video length and explanation is always a difficult balance.

[@pasasungur]

So there 2 plugs empty?

Yes, you may not use every factory harness depending on what trim level you have.

Hey bud I need some help with polarity for the 2019 Subaru Impreza base model front door speakers

[@ProvoBeastAudio]

Use a 9v battery and see which way the factory speaker pops. If it pops outwards, whatever wire is in the positive side of the battery will be your positive wire
