Hey all, I've got an 03 max with Bose system. Just replaced the stock head unit with a pioneer avid-x920bt. Connected everything(was the Most complicated install I have ever done, with the parrot bt system that was installed, the installer cut the wires instead of using harnesses, and also I needed to integrate the steering wheel controls, gps antenna and microphone as well as run a cable for the iPod - took 4 hrs - 3 hrs longer than I expected)

Anyways, now that the system is all hooked up, even when the h/u is set to full volume, it is not that loud. The hu only has 2v pre outs. Could this be the issue? Should I just replace everything Bose and toss new speakers in the doors? Or can I change the gain on the amp somehow?

 

Nah, it's not the 2V preouts. The preouts are there when you need to connect the HU to an external amplifier. Did you bypass the Bose amps?

I would just tear out the Bose stuff and go aftermarket. It'll sound better in the long run!

 

Thats def. the best way. Just run all new wires from the back of the HU to each speaker so you dont have to deal with Bose BS. Thats what I want to do, just need a little help

 

What help do you need? That's what I am going to do, I know how to do it, but wanted to know if there was an easier way. I do have a set of component speakers I got for free with my hu. They might suffice until I buy some type rs with an amp

 

running wires isn't too bad. probably the hardest part would be snaking the wires through the door grommets. it was a royal pain in the *** for me to snake several runs of 14 gauge through mine.

 

FAIL.

It Is the 2V Pre outs. what he needs is 4V. like Bose intended for their external amps.

just ebay the SPLIT-4004 by audiopipe.. its a 18 channel splitter for 20 bucks that ramps the Voltage to 4V. for everyhting. its pure win.

 

The 2V preouts are for connecting external amps via RCA interconnects. It has nothing to do with the Bose amps. And the last time I checked, stock Bose amps does not have RCA signal input. And even IF he used some 4V preouts, he won't see anywhere NEAR those rated volts unless he maxes out his headunit.

I have 5V preouts on my Eclipse deck, but do I see a constant 5V? No.

 

It's not the 2volt pre amp outputs, I have a clarion eq that bumps it up to 8 volts and mine still isnt as loud as the bose unit

 

Yea, I saw that was going to be a pita. What I ended up doing was splicing into the wiring loom that runs along the doorsills. I just connected my crossovers there, and cut off the stock bose plug in the door. Connected the speakers directly, and it saved me from fishing wires.

Also, My 5 1/4" speakers(they were free, I didn't choose them) didn't come with 6 1/2 adapter plates so I ended up ghetto-rigging it using some 6x9 adapters and double stick tape. Also used the tape(the foam kind) to mount the tweeters in the stock location, which worked AWESOME.

I do think the problem is the preamplifier voltage(yes the stock Bose doesn't have rya jacks - the harness that crutch field supplied converted the factory harness into some RCA jacks for pre-amp inputs), im just going to scrap the Bose system and buy a Polk 8" sub and amp next paycheck and be done with it. The free pioneer speakers in the front sound great even without the sub, but I def want that extra thump
