Prius C Aftermarket Stereo

Being new here , i was reading some post about aftermarket audio system , my question is : is there a how-to remove the factory head unit on the prius c ? thanks in advance.

 

Hey Everyone

Just wanted to add the Axxess brand ASWC steering wheel control module is easier to install and program than the PAC SWI modules. No resistor required either, and it auto programs, wire it up, plug it in to the radio, turn the key to ACC and the module is programmed.

As for a kit, use a Metra 99-9999 universal single/double din panel, needs a little trimming to fit but it works great as an interim kit until an actual kit gets released. If anyone needs one pre-trimmed we can help you out.

 

Has anyone tried the Axxess brand ASWC steering wheel control module. Do all of the steering wheel buttons work properly? Where do i get wire harness? Model number please? And is the metra 99-9999 the only temp rig. Cant deal with lousy stereo and cant be sloppy .Thanks. Wharfe, What are you gonna do to protect speakers ill probably match what your doin to protect my speakers

 

Thanks Wharfe , i will try that over the week end . i'll keep you post on how toufgh the screws were...

 

Well. I decided to go with a jl 700/5 amp its 80x4 rms and 300x1 rms. Wonder if ill need a cap. I have hat imagine 6.5 speakers up front alpine spr-60 in rear and 10 jl w3. hopin all fits ok. All being shipped as we speak. Do all aftermarket decks need the antenna part from metra or just the clarion?

 

The Metra 99-9999 has to be modified to fit, it is essentially a 12 X 12 piece of ABS plastic with gridplate on the backside, and a pre-cut double din opening in the middle. It makes life WAY easier due to the double din opening already being cut. You have to grind the edges to fit *behind* the OEM radio trim.

When done it's not perfect, but it's much better than leaving the gap between the aftermarket radio size and the OEM radio size.

Theoretically you could trim the 99-9999 to perfectly fit flush with the OEM radio trim panel, but that would take a lot of work to get perfect, so it's way easier to leave it behind the OEM radio trim (this means it doesn't sit flush with the face of the OEM radio trim).

Hard to explain thorugh type, easier to see in the below photo (not resized so apologies for the hugeness of it). Look at the edges around the radio trim, you can see the 99-9999 sits *behind* the OEM trim.

 

Well I installed my stereo today now I have a warning that says hybrid system problem park vehicle immediately . I don't get it . I got out and looked at the back seat and my power cap was inactive as well . Tried hookin stereo up direct same error. Unplugged stereo ... Same deal . Even reset battery . The Power cap works... maybe a bad surge. ? Had the cap and amp grounded together in a distribution block. Maybe that was it should've grounded amp and cap separate? Anyway will dealer have to reset something cause I'm not sure what happened.

 

Update on my scenario did some reading and found out that the 12 volt battery was drained down a lot and charged it up and now all is fine thank god lol

 

i'm pretty new to stereo installations only installed one before and took me hours does anyone know what harness i should buy for the head unit? thanks!

 

Wharfe, I have a question for you. I found a brand new Alpine KTP-445 (without U) for $56 with taxes and it seems like a good deal. I also found in internet that this unit with some rewiring should be compatible with most of the HUs too. I want to put it together with my original HU and a set of PolkAudio components in the front and coaxial at the back. Does this thing drain a lot of power from your battery? Can you see any difference with your MPG?

 

Thanks. The last question. Is it should be powered directly from the battery, or you got the power from some other location? I don't have the amp in my hands yet, but in the box it looks like the power wire is tiny.

 

Thanks a lot for all your help!

 

Today I ordered KTP-445U. Im going to install that to the factory HU, and connect SPR60 & SPR60C. Any tips on installing Power pack. Thats where I'm most nervous about installing.
