Neil plays it down but he really knows his stuff and is so talented. He worked on my car many years ago and it still performs perfectly. 😀

Love the channel!

This Z4 has the base sound system same as in my car, this system does not have an external amp from the factory. Z4s with better factory sound systems do come with an external amp which is mounted where you mounted the crossovers. To hear the sub properly don't you need to open the ski hatch pass through?

Hey joe bloggs, well if it didn’t have an external amp at the back then what the hell did i wire it up to 😆 funny you should bring this up as my next video is another z4 which does have the larger amp mounted where i put the crossovers but im also installing a DSP so took the factory amp out, as to the ski hatch, bass is non directional and is more about pressure, but there could be some small gains in opening the hatch, thanks for watching and commenting.

@@creativecarsounds4484 The base sound system in the E89 which is what this car had and what mine did, does not come with an external amp the amp is built into the head unit. Which is why it sounds so crap! You can tell if it’s a base system as there are no subs behind the seats in the bulkhead as per this car. What you showed on the left is the ULF or MULF Bluetooth combox and USB box. Only the upgraded sound systems option numbers S676A or S677A come with either a 245w or 650w amp respectively in both cases it’s mounted on the right where in the base sound system there is a blank space. In my car I upgraded the system adding a MMI CarPlay box and taking the feed from the speaker wires at the back of the head unit feeding it to an AudioControl LOC LC6i and from there feeding it to two amps one mounted on the right where you put crossovers powering the 8 speakers (I upgraded all speakers and added the door tweeters) and the other amp power two subs I mounted in the rear bulkhead in the same place where the factory subs are in the higher end factory options.

Bet your car sounds good, the recent Z4 I’ve filmed but not uploaded sounded great after the upgrade, its strange that you don’t think that the far left small box in the video with the heat sinks isn’t the amplifier as it was the last connection point on the audio network and the heavy wires that came out went straight to the speakers, it also had voltage increase when the volume changed, the Audison SLi4 connected to those wires and gave the exact signal needed for the sound system, found the part details BMW E89 2012 Z4 HARMAN BECKER AMP AMPLIFIER ACTIVE SOUND CONTROL UNIT E70 E71 X5 X6 9286863 B165 *218 maybe this car didnt have the full basic setup as the unit was made by Harman, must have been some sort of 1 up from basic

@@creativecarsounds4484 It is strange, my car has two boxes on the left but both are much larger than the little thing which you connected the amp to, no idea what that is in your customers car yet I am 100% certain the base 6 speaker system has a built in amp in the head unit with no external amp. Is the car UK spec? Yes mine sounds great but probably not as great as if I put a DSP amp in but hey ho it’s an upgrade for another day 😃. Look forward to your new Z4 video. 👍

Yeah its a UK spec, you should definitely add a DSP the difference is amazing, the next video will be up in about a week, its much better than this one, i think you’ll enjoy it 👍
