hey, im going to try and repair my rear amps (90se)
-capasitors- are they the 2 large black and gray battery lookin things??
if so
the front ones read 1000uf? so do i just buy the same ones from radio shack?

are the rears the same?

any tips..? (i searched fooooorever) any info will help

thanx in advance

If you need to ask those questions, you probably SHOULDN'T try to replace the capacitors yourself... They carry a charge, and if they're large and 1f, they'd probably hurt a LOT if you got shocked... That, and they're normally polarized, and reversing the polarity will cause them to pop... Possibly violently, they usually contain a corrosive material and smell REAL bad when they do pop...
Also, how do you know it's the capacitor?

ChrisCheezer

-it doesnt sound to hard, and a friend of mine said it wouldn't matter what way you put them in..
- i like pain..

-cuz it buzzes and pops when it comes on and sometimes it just doesnt come on and it just buzzes

chris..get new friends...or get friends that knows wtf they are talking about.

ChrisCheezer

***!




damn... but it sounded sooo easy,
now i need to find new friends too!?!, eeef, this is going to cost me alot

Taegost

I thought friends were free? Oh, wait... I work in IT, I should know better then that
If it's buzzing, it might be that either A) The input or pre-amp is messed up and not sending the signal to the rest of the amps and the rest are picking up white noise, or the noise dampeners... Could be one of the chips is not working right... It's something before the amps though, or one of them, which doesn't help much...
And no, I don't want to help troubleshoot

if you don't know what you're doing, please send them off for repair or let someone who DOES know what they're doing replace it.
if you have to ask what a capacitator is, then you don't know what you're doing.

yeah what Matt said. Send them to me...I am no expert on electronics like Matt and Craig (and a few others) but I have rebuilt several Bose amps.

$25 each if it just needs the caps.

ChrisCheezer

25 bucks?!?! no max.org deals? hehe

aight.. i thought about it, i guess i wont be doing it after all

Michael

that is a .org deal. Research it a little and a lot of places want close to 100 an amp. The cheapest I found a while back was a little over $50. So yeah I would say half off of the cheapest I found is a deal.

Taegost

It might be cheaper and easier to just replace them completely with aftermarket stuff

Michael

It would be better thats for sure but not cheaper. Can you find good speakers for the door (6.5) rear (6x9) and a decent head unit and amp for $100? Heck you cant even find really cheap speakers for that. That is what it would cost for rebuilding 4 amps.

Honestly the best thing would be to buy some good speakers, amp and head unit...only problem is you are talking at least $400-500 for cheap (but can probably live with) stuff.

A capacitor is an acid (much like in your battery) incased in metal. When hooked up backwards, the explode sending metal scrapnal and acid all over the place. In one of my electronics classes, we had this plexi-glass enclosure where we could blow them up on purpose, tons-o-fun.....but I'm willing to bet watching your car burning down will be more painful that the metal/acid. But what the hell, you need to save $25, and you like pain.

LOL!!! WTF are you smoking? ACID? uhhh, no. electrolyte, yes. most of the time they're a salt water or light oil base, NOT acid... you're thinking of batteries, son.

Taegost

Yeah some of them are corrosive, but not acid
We used to blow them up in school too... But not in a controlled environment... We got real good at getting them to the point they were about to pop and tossing them at the freshmen

ChrisCheezer

i went into the car parts shope (speed shop) to get a headlight bulb (xenon white), cuz my right one blew out..
-i came out with a new set of lights and new 6x9's rear speakers.. they sound great! 280 watts i think there 3 way.. and they have a huge 50 ounce magnet on them.
installation was a snap
the speaker set was selling for 100 bucks... i got them for 52.99 (w/tax)
*they sound much better then the bose and i never have to worry about amps for the rears again... im just looking for a nice little 100W amp for them (and with my luck it will blow out in a week or 2)

my advice for ppl with blow rear bose speakers or amps.....
Get a nice set of after market's.. pop them in.. (25 min installation)
and get on with ur life! heheh

peace

when you pull the bose out, can the aftermarket speakers just hook right up to the same wires? My sister just emailed me that the bose in her 89 gxe went out and she wants me to fix them.

Michael

so you already had an aftermarket head unit. Just for those reading this and dont know that...you can not just replace the rear speaker and by pass the amp IF you dont have an aftermarket head unit.

DonQuixote

OK, I think I posted this on another bose amp repair
thread, but all the posts I read only talk about the
small caps...I have my front amp open, and I see two
larger 820uF-16V next to the coils (C19 & C?).
Do these stay good?
