HiFi system upgrade

Want to upgrade my sound system and there are 2 options that I wanna go with but can't pick one. Should I go for bimmer tech alpha or bavsound? What do you have guys?

I think they both use relabeled Audiotec/Fisher Helix DSP/AMPs

In the case of bimmertech its the Helix 86dsp
and in the case of bavsound its the Helix BMW7.
86dsp has one more channel which means you could
go active on the front doors.

BMW7 has more power especially for the under seats.

I think they both give you a tune and some sort of mounting hardware.
To get more out of it you will need new speakers or the Front doors
and floors. The biggest problem I have with bavsound is they don't list
the power rating on there speaker or at least this use to be true.

You might want to get quote from Unexpected Creations for the same stuff.

The helix match speaker set for the fronts is a more reasonably priced set
for the fronts. Than offered by bavsound or bimmertech I believe.

Thanks for all the detailed info. Yeah, prices kinda high, the main point for me was easy swap, but at this price I might just go to the sound shop so they will do everything for me with their speakers but I'm just afraid they gonna put some noname brand speakers that I never heard of.

Buy a set of BMW Individual Audio speakers off eBay and take them into the shop. Also, get some sound deadening material as well. The IA speakers are top shelf and will fit. It's really hard to beat the quality of the BMW IA speakers for the money. The only thing I'd probably at some point is ditch the BMW IA under the seat subs and get a better option that is more "mid-bass" oriented.

Just make sure the set comes with the special cross over & harness for the front door speakers.

As far as a better amp, the helix is a great option. A little pricey but for plug & play it's hard to beat.

Don't go to some hack shop that will push there stuff on you
and don't know there way around a BMW. You would be better off
on the track you were previously on.
There have been some horror storys here of people that have done
that.
I would at least call Don and get his opinion.
Also he might know somebody closer to you that is good .
He is in Edison NJ.

The plug and play packages generally don't come with a proper power
connection to the amp/battery . Check on it.
