Cheap Logic 7 Speaker Upgrade

I am doing this as a supplement to my NBT Evo. I am going to see if a F series logic 7 setup will be a nice upgrade over the E90 logic 7 speakers.

I bought a F01 7 series amp for $230 and a full logic 7 speaker set up from a F36 for $250. I already have the amp installed and it is over powering the factory 4ohm subs. The speakers and subs will come in sometime next week. I know the F series 8ohm subs will fit but the rest of the speakers may or may not fit. I wonder how this setup will compare to a $1000+ bav sound system.

Here is the new amp installed. I added a noctua fan wired to the cd changer pre wiring.

I am guessing that amp is not even compatible with Logic 7
in a 3 series. Even in a 3 series stuff from a an e36 e46 and e90
are different. The amps are not the same.
You can't mix model years like you are doing the sizes and wirings
are not the same.

In a 7 series some of the channels came from the Head unit
in some years.

The amp was plug and play and I have been using it for the past three weeks. You need it to fix the NBT Evo call echo.

Center Speaker: PNP
Front Tweeters: PNP
Rear Tweeters: PNP
Sub Woofers: PNP
Front Door Speakers: Slight modification
Rear Door Speakers: Slight Modification
Rear Deck Speakers: Will not fit

Overall I would put in the 8ohm subs again but the rest of the speakers were a slight improvement. I have three extra tweeters from the F36 that I might install down the road.
