Stereo Problems

[michaelroy]

Hello All

I'm new here and need some advice if anyone can help.

A few months ago I heard some cracking through the speakers, my car has the premium stereo system with DSP I think.
I searched online and found that there is a common problem with the amp becoming submerged in water caused by a the positive battery cable opening.

I have fixed this so no new water gets in.

The amp has been taken apart dried out and cleaned.

Today I connected the amp back in and the original stereo and the stereo powers up but still no sound, I have checked fuse 47 & 50 and both are OK.

There are no LED's on the amp itself so i cannot tell if it actually powers on.

I have bought a new stereo and this was the same result.

the amp is part number 086496064 which seem to be about £1000 new or £400 second hand. Is it worth it? are there any direct swappable amps that would replace the potential dud one?

I know i could rewire all of the speakers to a new amp but want to see if the original can be fixed first, read something about might need programming is this true?

Thanks all

I had this problem caused by a leaking battery my amp was covered in white acid residue it still worked just when I turned it up to loud it would crackle or go onto one side of the speaker channels. I did the same got a new head unit plugged it all in and no sound so the bme amp would need bypassing. I took it to a stereo shop they looked at it and did some rewiring. I was told the problem was bmw had over engineered there audio system having lots of speakers driven by the amp in the boot. I alkready had a monoblock amp which only gave me sound to some speaker and not the subs behind the seats. I had to get another 4 channel amp to get all 10 speakers working in my car 6 in front and 4 behind the seat. You can pick up a used amp cheap on ebay maybe check with audio shop first to see what channel amp you need probably be same scenario as mine. Think I paid £60 for my alpine amp and subwoofer off ebay

well i upgraded my DSP carver system because the OEM head unit is a relic and I wanted bluetooth.

new head unit has superior sound quality - pioneer X8700DAB, DAB radio - superior sound quality to normal radio, bluetooth (2 devices at same time) and a lot of other nifty features. It cost roughly £170.

I then had to get a new amp as you cannot upgrade the DSP carver system head unit without upgrading the AMP and head unit, I got an alpine one for £400. New wiring kit, and some passive crossovers as the DSP amp does all of this for you, another £50ish or so on top of the amp.

Then had to get fascia, harness, converters, etc.

All in it cost me about £1K for the full system installed and the sound quality I would say is now ridiculously good. I sold my DSP amp on ebay for £200. So I managed to recoup a small amount back.

If you value sound quality then I would highly recommend doing what I did. If your happy with the current system get another amp off ebay for £200.

I'm using the stock DSP carver speakers everything else upgraded and the difference is like comparing a set of £30 headphones with £300 headphones. I'm amazed at how big the difference is which shows that the stock amp and head unit aren't that great.

If anyone near Glasgow wants to hear my system and are local I would gladly show them.

However it was still very expensive IMO. I should of just got an aux in added and then used one of those £20-£40 kits off amazon that plug into the ciggy lighter and convert bluetooth into aux out.

However I will get my moneys worth as I do like my music.
