Well I am thinking of spending 700-800 on upgrading the sound system in my car. So far ive searched all over, this site, bimmerfest and DIYaudio.com.


With my budget i think i will be limited to an amp, front speakers and maybe a processor (if needed).

I will be able to install it myself. For amps JL XD600/6 but it is OOS and i just found a MB quart NAU 660.....

Not sure if the MB is a good amp or not. its cheap and a 6 channel, and its available. If its not a good choice lmk, il steer clear.

can you guys toss out ideas for front speakers?? also when hook up my I fone and use it as a MP3 i have to turn the volume up on the phone all the way.

Once you turn up (car radio) to the point where its pretty loud, bass, etc etc there is a bit of "feedback" or distoration?? any fixes to this??

Replacement of the OEM amp requires a 6ch aftermarket amp with balanced-inputs.

$500 can give you an XD600/6 and the DLS R4 component set for the fronts (if this is an E90) at eBay.

I do not know if that MB amp accept balanced inputs, but I do know that the XD600/6 for sure does.

ok, any ideas on the hiss/feedback/static issue?? if you use the cd player or radio it doesnt happen.

I have not experienced any hiss in any of my XD600/6 installs so far.

You should also be picking up Technics Harness

Because it means not cutting wires to install the amp plus a buffer relay
for the remote turn on signal.

[Rival]

you mean a wiring harness?? In past cars you just mate the same colors on the harness to the same colors on the CD deck and your GTG??

and you explain a little further?

Technic makes a plug and play harness
This means you don't have to cut any wires .
It plugs right into the amp plug/wiring harness where the old Hi Fi amp goes.
It also buffers the turn on signal with a relay.

Plugs right into the amp connector for Hi Fi he also has other
types for the other systems. Also everything is labeled.
There are multiple pictures of it in that link he gave you for his sisters
upgrade, with only tweeters and a XD added.

Thanks for posting this! This is my third post so I can PM and/or start my own thread. I am looking to upgrade my 2008 335i e90 with Top HiFi and dying to get started.

This harness does not apply to top Hi Fi because of the Fiber Optic connection(the one in entry 13 but Technic has Top Hi Fi solutions to I believe.) between Head Unit and Amp. The Top Hi Fi is harder to modify.
There are other solutions for that system all the solutions are listed in the audio table of contents thread.
