Hi, Newbie here, I am on a tight budget here and am trying to hook up a amp to an existing Bose head unit that has no output jacks. I have to know how to make this work and what wires to connect to harness to head unit and plug into the amp with rca jacks. Hell I don't even know if this is possible. Thanks to all that can give me advance...

It can be done. You need a line-output convertor. I haven't used one in many years, but the Navone was a really good one. PAC also makes a few. The wires you will need to tap into will depend on the vehicle.

really, it depends on the vehicle. with a LOC you need to snag the signal at the speaker or find the factory amplifier and a wiring diagram. Bose systems use external amplifiers, sometimes mounted to the speakers themselves. You can buy an interface for your Bose head unit from PAC and other OEM integrators. Those end up working out the best for newer vehicles.

The other trick is where to get a remote turn-on signal for the amp. unless you can get one from the LOC, factory interface, or factory wiring you need to come off of the radio ignition wire, and add a fuse and a switch. you want to make sure to turn the amp off whenever the head unit is off.
the rule is:
amplifier off first, on last.

Thanks for the super quick replies. My son has a 2002 Acura RSX that I am trying to do this in. Are there big name local store that might sell the line output converters. Thanks

Agreed. props to Crutchfield's customer service. If you don't know what you're doing but insist on DIY - they are the only internet based shop to see. A reputable local shop is even better.

why a switch if you tag an accesory wire?

because you may want to turn the head unit off while the car is on. without the switch you should NEVER turn off the factory head unit - which is just stupid.

if you don't turn the amp off when the HU is off you'll send damaging thumps and pops to the speakers/subs which will destroy them.
