Need help, installing an Alpine Powerpack KTP-445U and Bypass the Factory JBL Amplifier!!!

I need the steps for installing an Alpine Powerpack KTP-445 amplifier in a 2012 Prius Five, with the Toyota Entune Headunit and the JBL Green Edge system and the Factory JBL Amplifier.

THE REASON IS THAT THE PREMIUM JBL SYSTEM SIMPLY SOUNDS TOO MEDIOCRE, AND YES IT'S LOUD ENOUGH JUST NOT CLEAR ENOUGH, AND JUST UPGRADING THE SPEAKERS WON'T DO THE JOB BECAUSE OF THE PRIUS SYSTEM POWER LIMITATIONS.

1. I figured I need the Wiring diagram for both the Headunit( For the Amp Remote wire).

2. And The Wiring diagram for the Factory JBL Amplifier( For the 4 channels peaker wires)

3. And the biggest challenge so far is finding a way to bypass the JBL Factory amp in a way that let's me keep All the Entune Headunit Functionality intact.

And yes, I'm aware of the 30 Amp MAX Draw on the Priuses, that's why the Alpine Powerpack that I've chose, has a Maximum current Draw of 15 AMP.
So it's within the Prius safety limits.

I will upgrade the speakers with 6x9 Infinity KAPPA 93IX in Front and 6.5 62IX in the rear doors that have a 2.5 Ohm Impedance.
The Speakers are Rated as 2.5 Ohm Impedance,
And the Alpine Powerpack supports both 4 and 2 Ohm loads in the 4x45W configuration.

I'm prety OK when it comes to DIY as long as the instructions are solid, and I'm not afraid of a challenge so PLEASE HELP!!!

 

Damn typos!!!

 

If someone with TIS Subscription can PM me the downloaded PDF Diagrams for the HeadUnit and the Factory JBL amp, I would appreciate the help a ton

 

Hi guys so I took some pictures of the JBL Green Edge Amp, with the Power Pack next to it,
I thought the 3rd Gen Prius has 3 connectors on the JBL Amp,
But after I removed the plastic cover from the Factory Amp, I was bummed to find that it has ONLY 2 CONNECTORS, since I bought all 3 harnesses on eBay, from the 3 connector model(2 white and 1 blue color)
Mine only has 2 white color connectors

 

Yes I agree, but the LC2I is a more affordable solution since I decided to better run the KTP-445U Bridged at 2x90W RMS at 4 Ohm load,
And I actually ended up buying(found a good deal on OfferUp) a pair of
Alpine Type S-S65 80W RMS 4 Ohm, 88 DB, 70Hz-22KHz , 2 way Speakers, Instead of the Infinity Kappas.
I'll definetely need some solution for a Ok LOW END(Maybe an Under Seat Powered Subwoofer (since I need all the trunk space I can get, but that is definetely for another day.
My budget is pretty tight, so I'm Not trying to go all Audiophile level, just get a entry level of decent sound quality.
I also must retain the Factory Headunit, for better or for worse

 

I'm not sure that your math is correct,
If you have 2 Amplifiers of 1200W RMS Each, (which I highly doubt), totaling 2400 W RMS Total Power Output then,
If we use the formula I=P/V, then
2400WDivided by14V(Roughly,13.8V to 14.2V in Prius Ready Mode)= Roughly 171.5 Amps,, Not accounting for other factors.
And, if the 30Amp Draw limit it's not a real thing, then I can get the Subwoofer I want, (But I think it makes sense that it is a real limitation, because the Prius doesn't have and a Traditional Alternator, and it's all about efficiency, then the big load will drain the HV battery pretty fast, just trying to charge the AUX 12V Battey), and the ICE will run Non Stop, but maybe I'm wrong.

 

I rried to send you a PM, but every time I click on the "Start a conversation" link under your profile, it gives me an error message.

I Can't send any Pm to you, it gives me an error every time I've tried to send it.

Please post some picture with the 30 Pin Connector Layout, if you can.
I posted here the Pictures of the JBL GreenEdge Amplifier and it's 2 connectors.
There's 2 wires of each color, in the 30 Pin connector,(One for Squaker and One for the Woofer)
I need to know which wire of the same color Is the Woofer, in total 8 wires.
Before I'll the factory harness.
Please!
