Where Is The Amplifier

[cagrikeskin]

Hi. I have a problem about my sound system. I have a Z4 E85 2006 2.0 My business CD suddenly started to play bad. I have sound quality loss. I thought it's a problem about amplifier but I can't find where it is. Some models have it next to the battery at trunk but I don't have there. Do you have any idea? Thank you.

Do you have the upgraded sound system then? If not, there is no amplifier and it will be in the Business cd unit itself.

If you have one it will be either in the battery compartment or on the rear bulkhead.
