Ok the situation is this.

I've gotten sick and tired of the bose in my beater 95 maxima not working. I've had the scosche adaptor for over a year now but hadn't gotten around to installing the headunit.

I went in there today to install it and discovered something, someone did a GHETTO bose retrofit onto this car. What that means is that the speakers all appear to be bose (except one perhaps, it has a larger magnet than the others) but instead of the bose amps being on the speakers, they put them right behind the bose headunit.

What this means is that there is a giant clusterfvck of wiring, the stock harnesses have been mangled to ****, etc. The wiring is so jacked up that it was impossible to make heads or tails of how this retard who installed this crap had things run. So what I did is I basically pruned things down til I was back to the stock harness - bose amps were no longer in the picture.

Since I won't have the BOSE amps to mess with, I got to wondering if I can just hook my aftermarket headunit directly to the BOSE speakers. But then I got to thinking that the Bose speakers might not be the correct ohm rating, and I don't want to burn up my headunit.


So, what ohm rating are the stock bose speakers, and can I just hook my aftermarket head unit up to them safely if I just hook it up directly (pretending they are just like any other regular speaker out there).


It has been literally like 6-7 years since I really messed with car audio so my memory is hazy. Most speakers are 4 ohm, right? If the bose speakers are 4 ohm then I should have no problem I think. But if the bose speakers are 2 ohm then I am going to be running the head unit's little amp twice as hard, correct? If the bose speakers are 8 ohm, then the headunit would only put out half of the wattage it should, right?

I don't really care about having super sound quality, so if I can use the speakers in the car right now I'd like to unless it will cause me problems.

 

1 ohm, they test out at around 2 though. If you use a metra 71-7551 and a high voltage headunit you should be fine.

 

70-7551?

 

what would I use that metra 70-7551 for? i looked it up and it just looks like it converts the nissan harness to RCA jacks - for what purpose?

how do I know if my head unit is a high voltage head unit. it's a 7 year old Panasonic DF-100.

 

fvck. Read the post wrong. Carry on with the 71-7551.

 

Actually, I believe i was mistaken, metra 70-7551 is correct, and I'm not sure how you would be able to hook up such an old deck to the bose without replacing the speaker as well. I don't even think it has any pre-outs? Does it?

 

It has one preout. preouts just send an unamplified signal to an external amp though, correct? I don't have an external amp so I'm confused as to why we are discussing preouts?

I just realized you probably meant "high voltage preouts" when you said "high voltage headunit."

I'm not trying to use preouts i just want to hook up the normal speaker signal wires (the purple, green, white, and gray wires) to hook up to the bose speakers just like normal speakers (because they are withOUT the bose amps, the bose amps are no longer installed) and I'm wondering if I can safely use my head unit to power the bose low impedence speakers.

 

Ah... I don't know how you got the bose speakers to work without amps, they should have fried the oem headunit or any other HU by now. You need to replace the bose with some cheap 4 ohm coax's to work with your hu. Thats about all you can do to remain cost effective.

 

the stock amps were in there and a stock bose headunit, but like i said they were ghetto retrofitted - the stock amps were in a different location than the actual speaker was, just connected by wiring. tonight I tore the stock amps out and the bose head unit because the bose was driving me insane. I was thinking i would probably have to do just what you said, get some cheap 4 ohm coax speakers, but i was hoping i might be able to avoid it. guess it's time for a trip to best buy.

 

Yea, or wal-mart, get them even cheaper.

 

Get yourself new speakers.

Since the original Blose speakers, amp and HU were installed in a mess and worked in crappy manner, just get rid of them. However, do not remove the existing wiring from center console to four/six speakers.

The common aftermarket HU will work with 8ohm or 4ohm speakers without any problem. Also the connection would be clean and easy. It's lousy to use adapter here and converter there.

Best wishes to your audio system.
