would like to add 2 bose spkrs to dash pad on 88 cpe plan to put spkrs only to pad and remote amps where ever they will fit under dash and either run anther spkr relay or tap in exhisting relay has anyone done this is it feaseable

 

huh? can you try this with some punctuation?

I will save you some angst, even if I am not 100% sure of what you are asking, but don't try modifying the Bose systems. they are not upward mobile, if you know what I mean.

you might want to try asking this over at the Audio/Electronics section.

 

You want to remove the Bose from the doors and put them in the dash? It sounds like a waste of time, but here goes...

The 4" speakers are probably too deep to reinstall the dashpad with them installed ot it. You could just leave the amps in the doors. There's room directly behind the stereo as well. I have both my component crossovers back there with room to spare.

The dash locations are solid plastic with a frame for a 4x6 speaker behind it. I did a custom setup to mount tweeters flush under it, and cut the plastic out under the speaker fabric. Then I modified the Bose pods in the doors to fit a 5.25" component sub. But you can't use the Bose headunit with aftermarket speakers.

 

no punctuation i have spare bose skrs and amps i want to ADD 2 more spkrs to dash

 

I'm sorry bogus, but you have to admit that's just TOO funny!

If I had to guess, I'd say this gentlman ain't from around these here parts.

i dont type well and hate typeing my wife who knowa very little about cars understood my question i joined this forum to get tips and shortcuts that arent in fsm not to get a bunch of smart *** comments if you dont like my typeing or dont have anything usefull to say then dont respond these are not my firs vettes igot my 1st in 1963 new i was 18 have since had many others long before the internet when i was younger ran quarter mile midnite drags and slolum no longer interestd in speed or soupeing up vets been ther and done it allrready these c4 vettes are the slowest ive owned but were cheap run on todays enviro **** gas (thanks to you calif *******s who started all this enviro crap) and are a lot more fun to drive than a ford taurus or any *** crap i have no idea nor do icare what your response will be ive blocked your responses out there are others you can answer my questions without the wise *** comments

 

dude... it's not about typing... it's about taking a minute and being concise in your message.

apparently, you are college educated, how in the hell did you get that degree without being able to write a complete sentence?

 

ok...this is the second time i've heard someone refer to a 'speaker relay'. what exactly is a speaker relay?

 

in the C4 Bose systems, they had amps at each speaker, and to fire them off, they used a relay.

this relay could wear, and cause the speakers to not work.

In the early C4, the relay was behind the DIC, IIRC... or was it under the passengers side dash? I don't remember for sure.

in the later C4, it was under the dash, near the steering column.

 

so it is the equivelant of an external remote turnon...right?

 

essentially, yes. It's the blue wire.

 

 

Bogus, I am going to try this one more time. My wife is typing this with periods, commas, etc. I am dictating. In college I paid people to type my reports; at work I had a secretary to type them.

Corvette Kid, this is for you. You are a follower, not a leader, and no I am not from a socialist country yet (though I have lived in 2 of them).

Now to my original post. If there are any double e's out there, please feel free to jump in. This is not a vendetta between me and Bogus. I will make this as simple as I can.
My wife's 88 coupe came with a factory Bose system. I have 13 spare Bose speakers and amps and 3 spare radios. I have had the dash pad off. There is not enough room under the pad to put a Bose speaker and amp. What I want to do is take the speaker out of the amplified enclosure and put the speaker under the dash pad where non-Bose speakers would have been, run wires from speaker to amplifier enclosure (which I will try and put somewhere up under the dash). My original concern was will the original speaker relay be able to handle the added load? If not I will add another speaker relay to run these 2 speakers. I will not disturb the original door or rear speakers. I am just adding 2 more Bose speakers. I had already talked to the guy that repairs all my other radios and TVs. He said that he didn't think there would be any problem using the existing speaker relay but he us not familiar with Corvettes and doesn't fix Bose because Bose is proprietary and does not give out schematics . (By the way, this is where I have been getting these extra speakers and amps for $5 each. We have become friends because he too likes pinballs and I have fixed a few of his boards for him. He has junkyards dump off radios and speakers buy the box load.)


In summation:
1) Will the speaker relay handle the additional current or should I add ganged relay (one relay feeding another)?
2) Will these amplifiers cause any interference problem with the CPU
3) Will these amplifiers cause any interference problems with the digital dash circuitry?

In conclusion
1) If you don’t know the answers to any of these questions, don’t reply
2) Bogus, you are knowledgeable and helpful, but you can be an obnoxious ******* at times. I appreciate you taking the time and trouble to put some valid and helpful input
3) I try to help people too but I don’t post “I don’t know and good luck” and interrupt or hijack a post.
4) If I knew how to type and had the interest anymore I should be posting on C2 and C3
5) When I do post I know what I am talking about. I just don’t have the obsession or interest any more that I used to.
6) MoJo, this post should be on the general site. This audio site is a disaster.

PS by wife. Sometimes I have short weekend trips for work and I need to load up the back of my car. You can’t hear the rear speakers because there is so much stuff in there. When my husband had the dash pad out, I noticed speaker thingies and asked him why there were not speakers there. He explained why and showed me one of the big speakers that come with it and why it wouldn’t fit. Ever since then he has been toying with the idea and is going to work on this. I love driving my Vette to work until the weather gets bad and he keeps it in perfect running condition.
PPS My husband has a very short fuse at times. I am just his typist for the night.

 

how do you plan on wiring these amps? running new wires from the battery? or tapping off the stock amps?

 

First off IMO Bogus is one of the most knowledgeable and helpful people on the board.

I would say add an external relay, the relays tend to have problems as it is with the factory bose speaekrs, let alone some extras. My other big concern is where do you plan on picking up signal from. I deffinetly think it can be done although this is the first I have heard of someone trying to accomplish this.

Best of luck to you, and let us know how it works out

 

Now that I have a better picture of your plan, I can't see why this won't work, but I have concerns.

The amps are not that big, so they won't take up a lot of space, and if it was up to me, I would consider putting them into the knee bolsters and run wire up to the speaker.

My only concern: Bose systems require porting and very scientifically designed enclosures. Putting a driver up there without some kind of enclosure and port would compromise the sound quality of that speaker.

Essentially, Bose is all about taking junk drivers, junk amps, and putting them into rather expensive enclosures. I really cannot imagine this sounding quite right when done.

For all of the hatred I direct at Bose, they do put a lot of effort into the imaging, as such, adding two more, unfocused speakers, could really damage the soundstage. Besides, it might do bad things to the input impedence of the head unit - meaning - more load. Much like taking a stereo that is designed for 8 ohms, and putting a 16 ohm speaker on it, it will make it work harder. This could lead to damage to the output section of the head unit.

Now, much of that is guesswork, but it is rather educated guesswork.

If you want to do anything to the Bose system, I would suggest taking 4 of enclosures you already have, send them back to Bose, where they will upgrade the amps and speakers, all for $75.00 each.

This thread explains where you can get a different GM head unit that has a CD player in it that will a) fit the early C4 dash and b) adapts to that version of the Bose. I think you can find these heads for about $100.00, complete. Check with landpilot for more info.

I suspect this combo would actually sound pretty good, and maintain that "factory" look.

Thoughts?

 

I have to challenge you on your preconcieved notions about emissions.

If you ever visited LA 30 years ago, you would see exactly why this was necessary. Don't you remember the noontime night in Pittsburgh? Or the day the Cuyahoga River caught fire?

These are some of the upsides to the 'smog *****'. I don't agree with all their methods, but I sure to like breathing, and drinking, the results.

 

im going to tap off my my power window switch if i had a 99 fsm i would give you the wire colors

 

bogus i lived in la in early 50s if you put enough people in a phone booth you are going to grt a smell la has a unique situation with valley and air currents but eviro has become an ant american religion now its costing the average american billions in bogus junk science icould go on but as you know i hate typeing and wife wont take anymore dictation
