I'm new to this modification. I acquired a pair of 2007 roll hoops and I want to connect them in my 2005. Does my vehicle have a wiring harness in it like the 06 and up?
What exactly do I need for a wire harness, I would like to keep this as clean as possible. I couldn't find anything on modifry. Hardtopguy or lucid is what I read about but I'd like to know if anyone has done this to an 05. Thanks. Any links to this project would be great

 

I believe theres a harness you need that goes between the roll hoops and the radio because its prewired on the radio side already.i think its the same oneas if you were hooking up the headrest speakers

 

Yes! I know honda does not sell this separately. Does anyone make an aftermarket plug and play

 

I don't believe anyone makes a "plug and play" setup for speakers, but rear speaker outputs exist behind the radio for the addition of OEM headrest speakers. You should be able to connect the roll hoop speakers to these outputs. Check out steps 55 and 56 on page 11 of the PDF linked below..

I know you didn't ask but I'll throw my 2 cents out there anyway. Do yourself a favor and don't bother w/ the oem headrest speakers. They sound like shit honestly, and I disconnected them. You're much better off putting your money towards good component speakers and an amp for them if possible. The soundstage is terrible w/ the oem rear headrest speakers.
