Ok.. I've started this on my 2005 Prius. I'm intimately familiar with how the dashboard comes apart and goes back together, as well as how to remove seats. What I don't understand is why you went to all of the trouble to remove both seats, all the trim, the GPS box, etc., when you could have simply removed the passenger seat and run the very long Metra cable under the passenger door trim, and then up behind the ECUs on the right side of the dashboard, behind the glove box and over to the radio? It took me 10 minutes to remove the seat, trim and dashboard, to do that. What am I missing? Thanks for the video though.
Hi, that’s probably a better way to do it. Just didn’t have familiarity with that side of the dash and door. I had previously removed all seats to install sound deadening on the floor so that’s how I knew how to access the JBL amp. Also I wanted to remove the JBL amp and I’m not sure if you can do this without removing the carpet. Thanks for watching and hopefully your comment saves a viewer some time !! 😁
Mr. Dishes, I have been looking for this tutorial all over youtube, google and ask jeeves. You have finally delivered. This is by far the simplest breakdown I have seen that even a baby can do. I too completed this same project in 11 minutes and 8 seconds.
Easy Gen 2 Prius sound system upgrade without much hassle: Buy an Earstudio ES100 Bluetooth DAC Amp ($100 or less). I mounted mine on the side of the center console using Velcro. I drilled a small hole in the side of the console to connect the cable to the auxiliary input. Connect my phone to the ES100 via Bluetooth, and instantly have a much better sound system. The JBL amp is not great, but it's not terrible. What is terrible is the quality of sound that comes out of the FM section and the CD player. I also replaced the front speakers with Focal drivers and bought a decent 3.5mm cable (Audioquest Big Sur). What I've yet to do is reverse the front and back channel wires at the amp so that the you hear the back channel (which has better bass) up front. When replacing the drivers in the doors - add some dampening material while you have everything open. Cheers
I have an 09 with the jbl system. I wired in the steering wheel control and the correct bypass but added an amp the correct way on the bypass. I have put a lot of amps in cars and subs. The 20 pin harness behind the stock radio that I need the 4 wires out of.. illumination, accessory, power and ground to my new head unit. Idk which wires are which and I’m debating buying the “jbl adapter harness” for the radio as if I am keeping the amp, but only using that harness for the 4 wires I need for the radio to turn on. Is this what I need to do to solve my headache or is that the wrong solution??
you'd probably need this to connect the output of the amp to the main speaker harness, if you kept the speakers stock, or wanted to reuse the main speaker harness for new speakers.
@@samitobasi4668 are you currently using a analog to digital conversion module to send the head unit audio to the JBL amp? if so, the bypass will definitely improve quality as that unit degrades quality.
@@samitobasi4668 every time you pass the signal through another device, the quality degrades. so if your chain right now is this: head unit amp -> digital conversion module -> JBL amp -> speakers adding the bypass harness lets you remove the two middle devices from the chain, making it this: head unit amp -> speakers
If you have the stock JBL stereo - you can't even do the bypass because the stock JBL stereo outputs in digital to the amp which decodes it into an audio signal. If you have an aftermarket stereo - without bypassing, you have to convert the analog signal from your aftermarket stereo to the digital signal for the JBL amp, which seriously degrades audio quality. With bypassing, your audio quality is as good as the amp internal in your aftermarket stereo (this will at least be better than using the JBL amp because you don't have to do the unnecessary analog to digital conversion to feed the JBL amp). Most internal amps in modern head units from reputable brands (i.e. Kenwood) sound nicer than the stock JBL stereo with JBL amp.
Hi, I have connected video card in my Prius 2006 model. It's working fine I can watch videos songs. Now I want to bypass parking brake which I don't know how to do because i don't know which wire is the parking brake at mfd. Does anyone know which wire is that for brake?
For the rear tweeters, there is a passive crossover somewhere between the bypass cable and the speaker. for the fronts, its the same signal for door speaker and tweeter. I didn't put in a crossover for these, although I should (I blew the tweeter before). Instead, I have separate signal coming from my head unit for sub and full range speakers, so I set my head unit to cut off the low end to the full range (IDK, around 80-100Hz?) and the sub picks up the slack. Probably loosing some bass but it sounds pretty good.
FOR ME, THIS DID NOT WORK. The cable used in this video does not work in my 2009 prius with a JBL amp. The model of my amplifier is 86280-0w460, if you find this model number of amplifier under your passenger seat, please double check the wires before committing to this.
Sorry you went through this time suck! I know how long it can take to rip out your carpet. Didn't know the JBL amp is not the same for all of the Gen 2 years. I did some more research and 2004,2005 Priuses have JBL amp model number 86280-OW240 instead of what you mentioned. For the 2006-2009 models, you need the "AXABH-TY4" harness: www.metraonline.com/part/AXABH-TY4. I'll update the video description and add some in-video corrections mentioning this, thanks for bringing it to my attention!
@@alexanderdishes5384thank you for this video Mr AD.. I plan on upgrading the head unit to a Seicane unit for our Prius.. it works with the JBL amp... After the head unit.. i want to replace the speakers.. what drop in speakers do you recommend?
The JBL amp is *alright* if you have the stock head unit, because the stock head unit outputs digital, which the JBL amp converts to analogue when sending to your speakers. However, let's say you have one of the older Gen 2's without the direct 3.5 aux line and you want to stream music from your phone with the stock head unit, you have a few options: 1. tape deck to 3.5 mm converter plugged into a bluetooth receiver (crap quality), or 2. Radio bluetooth receiver (crap quality), or 3. replace your head unit with an aftermarket one that connects to your phone through bluetooth or apple carplay. Solutions 1 and 2 are garbage. The apple carplay head unit upgrade is better, but you will find you need to use an digital amp interface (like the Metra 70-8117) to connect your new head unit's analogue audio to the input of the digital JBL amp, which then converts it back to analogue for the speakers. The digital hop in the ADC -> DAC chain is unnecessary and lowers the quality of the output signal, and introduce a new potential source of failure in the system. The Metra 70-8117 unit I first tried quality control issues; only 50% of the time I started my car would the amp turn-on signal be successfully sent from the Metra to the JBL amp, meaning 50% of the time I didn't have sound. The replacement Metra didn't have this problem, but caused a constant hissing noise out of all speakers even the gain turned all the way down. Sound also suffered heavily from distortion at higher volumes. Using the bypass harness allows you to connect your high quality analogue preamps in your new head unit directly to your speakers, yielding the cleanest, loudest sound achievable with an aftermarket head unit (outside of installing a standalone amp of course) with modern features like Apple Carplay.
@@alexanderdishes5384 yea cuz i wanted to put a dedicated amp for some subwoofers for my gen 3 Prius but I don't know how to only attach it to the bass channel only, and i dont think there's alot of prius audiophile RUclips channels 😂 so idk what to do accept go hire a whole car audio guy

Thank You more Prius DIY maintenacne and improvement videos coming Soon
Thanks so much for this video. It really helped me out. I could never have done the thing without you.
Brilliant !
which type of head unit are you using in your Prius ?
Thanks for watching! Kenwood DMX907S. It is pricey but has flawless apple carplay support, and the amplifier sounds terrific.
@@alexanderdishes5384 thank you very much!

@@KONIXMUSICI do have one of those cheap 9inches android head unit so do you think by installing this bypass harness would improve my sound quality?
@@samitobasi4668 are you currently using a analog to digital conversion module to send the head unit audio to the JBL amp? if so, the bypass will definitely improve quality as that unit degrades quality.
@@KONIXMUSIC yes I do actually but is the equalizer in the android head unit is better than the amp?
