I dont think Studman is any longer among us, his last post was back in 2006...

Anyhow, most of the info on replacing the BOSE with aftermarket HU and keeping the BOSE amp + speakers came from him. I do have some questions after reading all his posts and I am hoping we have a new electronics guru in the house that could help me.


Background: 2000 with Bose system, wants to replace ONLY the HU and keep rest of the system.

From what I read this is what I need to buy: PAC ROEM-NIS2

Does that confirm? I also read in more recent posts that other companies are selling a similar interface connector. It seems like the PAC has dropped in price ($50) so quality is main concern: is there any better interface on the market or PAC is the way to go?


Studman's write up about connecting to the PAC:

Can someone clarify this statement for me please? It seems like his first attempt was to run straight from new HU to bose amp but failed. Then he got the PAC and run RCA from new HU to PAC and also failed. The third attempt is what seems to have worked and what I want to clarify how to do it: he ran the speaker wires to the PAC, so basically his HU had RCA outputs as well as speaker wires? Is that standard on all aftermarket HU? I am shopping for a JVC XG-700, how do I find out if I have RCA + speaker wires? And also important, it seems like the PAC can receive RCA or speaker wires, does that confirm?


Thanks in advance and I appreciate any inputs.

Well the easiest route to go is to get a metra 70-7551, and a HU that has at least 2 sets of outputs with at least 4 volts output each.

 

He is still around. PM Him. I know he is very busy with work right now.

 

this is a different approach and i'd have to read a ton about it for then decide which way to do it.

I felt like the PAC route was pretty simple as well and a better quality over them METRA. One of the downsides of the pac was price, but it has gone down, apparently, so no reason to really not go with the PAC.


Does that make sense or the metra has something else that I am missing? Because i thought the PAC was also plug-n-play

 

Really? i searched for his posts and the most recent post was dated back in 2006...


I'll try shooting him a PM!

 

Explain to me how the quality is any better with the PAC over the metra? The metra simply takes the high level inputs and converts them to low level for the amps, the metra takes the low level signal and has wires already in them to plug into the pre-outs which are low level already. The pac requires additional soldering AFAIK. The simplest way, by far is getting the metra 70-7551 and wiring it to a deck with good outputs.

 

Maybe the PAC is a better product than the Metra?

I have no idea which one is better, i just read 300 posts about these things and it gave me the impression that the PAC was better. I havent used any of them, i just want the best solution for replacing the Bose. And if the most labor involved is soldering, then it's all good, because that is a piece of cake.

 

Thats because the Metra has only been around about a year now, the PAC was around for like 4/5 years before the Metra came out.

I've used both and by far prefer the 70-7551.

 

Kewl, so that's why there are many more topics about the PAC than the metra.


So if I buy a (2) 4V HU with the METRA then all works better than the speaker-wires going to the PAC?

I was going to buy the JVC XG-700 but the outputs are 2.5V. The other possible options were the Kenwood DPX-502 and the Clarion 675, but they are 2.5V and 2.0V....


What happens if I use 2.5V instead of 4V?

 

Bborges I recently replaced the HU in my 2k with Bose setup and used the OEA-4 (model C4NN03) by Scoche which I purchased through Crutchfield for $40 (I don't know how to post links: Item #142C4NN03). After playing with the gains for a while I detemined setting them at max gave the best sound. The sound was similar in volume if not better than the stock setup. All the instructions were included with the piece. Very simple to install IMO

 

Interface/adaptors/etc ... such a waste when there is a much simpler and cheaper method. Either using a 7551 harness or do the work to a 7550 and make your own. Odd that some would find the PAC or any other interface superior ... Ive been doing this method since 3rd gens were NEW and havent had a problem...

 

i have nothing against the metra 7551, i just didnt find much info on it compared to the PAC..

Seems like the metra IS the way to go (and cheaper) but i cant find a double DIN mp3 with 4V+ rca outputs as recommended...

I asked this before and got no reply: what happens if I get the Metra and use it with 2.5V output (keeping the bose amp + speakers) ?


Any suggestion on a MP3 double Din with >4V RCAs?


Thanks

 

It will work fine, but have lower output.

 

ECLIPSE AVN FTW!! 5V outputs!

 

Right on! Not only it costs $1000+ but I already have my Garmin GPS that I paid $500... so yeah. I have to really be rational about this and stay AWAY from any Eclipse AVN, though they are sexy and great products.


If it wasnt for the fact that I use my garmin in the car and in the bike, I could totally sell the garmin and get the eclipse, but i need it on the bike.

 

He didnt say which ... AVN2210 MKII would work perfectly.

 

Sorry I missed the war here. While either unit will work, the PAC has been around for alot longer. Pearl96Max's way works just as well, so it's dependent on your situation. For those who lease the car, the PAC kit is the way to go.

Don........... what's going on? Haven't talked to you in forever.

 

Holy **** Jeremy lives !

Whats up bud? Gimme a call ! Havent heard from ya forever.

 

I tried buying both the PAC and the METRA.. the store canceled the PAC order and I only received the METRA... when in full volume it sounds awesome, but in lower volumes I can hear some humming/noise... so I definitely want to try the PAC to check if clears the sound.


Thanks for jumping in!

Did you ever get the PAC? I"m getting ready to do this, just curious. And why the heck does Crutchfield try to give me a different one, and when I search it says the 50 fits and the 51 doesn't. You'd think they would know by now.

 

I just went through this with crutchfield......you can request the metra 70-7551 instead of the 7550.....they actually sent me both when I requested this.

Nismos14 helped me out in another thread (thanks again nismos!).....he said that the stock bose system uses a low level speaker output, and not preamp RCA outputs. Thats why they assume that the 7550 is the best direct replacement.
I got my alpine 9885 last week and is sitting in my room waiting to get installed. Just looking for someone to install it in the north shore MA area, if anyone know of a quality installer?......

 

Sorry to revive a year old post, but I just installed my Pioneer AVIC 710 and of course have the 2.2V output problem so I also installed the PAC OEM 2. The problem i have is that it literally has not changed a thing, maybe made it a bit quieter. I have fiddled around with all the adjuster screws and all I can do is turn the volume down. Waht the hell is going on ???????
