Know what you mean with small bikes. Wife had a bucket bike when I met her. Basically a cheap low cc bike for organised car park racing. Don’t need to be doing 737 take off speeds to have a good time 😀

Other way round do it is to get something like an AVSS type thin walled high temp insulated wire and twist it together. It won’t take up as much room in the door connector garter. It was a tight fit from what I remembered . eg. Automotive Wires AVSS 24 22 20 18 16 14 13AWG Speaker Audio Cable OFC Oxygen-free Copper Thin PVC Insulation Car Wire https://a.aliexpress.com/_m0jAYWX

I think so , was a Jaycar speaker wire. 79x 0.2 strand.

Your thinking and logic is good. I have my 8s doing most of the bass range as they do it well and articulate the bass lines nicely with a reasonable amount of authority.

That’s looking good. Good combo of specs and ideal sealed box sub. 11mm one way xmax spec good too. If you compare to the focal that one really wants to be in an infinite baffle set up rather than a sealed box. With the dual voice coils you could go the other way with a 1 ohm parallel load depending on sub amplifier. More recently there seems to be a number of class D amps that are 1ohm stable. You just do the old I R / V ohms law and work out maximum current and then wire gauge that’s suited. But I suspect 2mm2 will be more than large enough at your target power levels. With the depth also allow room for the rear vent. If the gap is too small the sub won’t preform as well as it could. Think of it as additional spring loading if it’s too close to the back wall. One trick you can do with the enclosure is to stuff it. Has the effect of making the enclosure 20% larger to the sub if you are tight on volume. If you can fit it looking like an excellent choice. At the high end price wise ( JL audio ) I’d skip that and use a stereo integrity bm11 . Similar box size requirements and shallow depth. Bass wouldn’t be as tight as alpine but can go down to 20hz with 0.4 box and 3 inch depth.

See if you can find one with a qtc of around 0.5 which in a sealed box should be around 0.7 qts . Best combo of response and low end imho. Cabin gain will help bring up the sub bass region below 50hz can be anywhere between +6 - +10 db. Your plan for back corner are ideal as usually will play +3db louder than other locations . Important when running an 8. With QTS value if you haven’t already picked up on it a value of 0.5 is very tight bass but not so good on extension , 0.7 considered the best combo of rhythm and low end extension. 1.0 and above is considered boomy and flabby bass, but ok for hip hop genre where the overhang can work quite well. There is quite a good online simulator for TS modelling of speaker response for a given speaker Loudspeaker database. And cabin gain can be modelled via a tab in REW if your interested In going that far.https://www.roomeqwizard.com/ Edit, had forgotten about winSD modelling software, worth a look. https://www.subwoofer-builder.com/WinISD.htm

Score, Decent poly capacitor on the tweeter and good power handling, tweeter on a gimbal so you can align them better in relation to front. .Looks like a quality coaxial speaker.

Tidied rear armrest wiring and put all trim back into place. Tested USB C adapter with iPhone 16 which is USB C. Charging came up straight away . Phone also came up as USB entry on snapin adapter. Turned off CarPlay and tested , USB audio and Spotify app via USB c adapter , all working correctly. Charging is faster too via USB c adapter. 15 watts so more useful. So now I can run my 256gig thumb drive with quite a few lossless encoded albums off the usb b , Anything lossless audio wise on the iPhone can be played via usb c, handy for Apple Music lossless. Otherwise wifi CarPlay for anything else. Parts used.

Ran loom through car using factory route. Was out of earth points behind left rear seat bolster so added the larger earth comb that is used in BMW F3x and F8x . Suspect it’s for models with more factory option. I found the earth sockets seem to be a one way item so rather than taking them off a sandwiched the two combs together and added two earth connections after crimping on BMW connectors. Routed two 12 +ve cables to fuse box. Turned fuse box over and removed lock tab and pulled connector for fuse area 124 - 129. This section is associated with Idrive items such as hk amp fan , dvd stacker , tv module , telephone cradle , usb hub ( fuse 129 ) . Crimped on two new leaf contacts and click inserted into positions 124 & 129. Put connector and fuse box back into place. Ironically those fuse positions had fuses even though the car didnt those options. This fuse block run off terminal 30b so is power runs when the car is occupied. Power is tuned off when car is locked or after 8-20 mins if car is left unlocked such as when left in garage. So no worries about parasitic draw. The USB C has a backlight on pin 3 of its connector. The closest source for a light circuit is the rear console armrest led bunker light. The connector for it is behind the rear seat air vent trim. Used a pin removal tool on mqs socket. Crimped a new one with positive feed to USB c adapter.

G20 USB C retrofit. Adding power to G20 USB c charger retrofit. This involves running power from rear fuse box to centre console. Also replacing the primary earth point comb behind rear left seat bolster with a larger one with more connection points. Ill also take the opportunity to run a power and earth feed for a factory usb hub. Undecided on the retrofit at this stage. But will make it easy should I go that way. Ordered connector parts via BMW dealer. Roughly $40 for comb / earth pin connectors and battery box insert connectors. Found some red / black 0.5mm2 cable ( correct colour ) via Repco. Used 0.75mm2 for brown earth because handy gauge to have size and had to buy a 20m reel. Both single g20 USB c adapter and usb hub only need 0.5mm2 cable for power and earth. The wire for the backlight of the USBc is a 0.3mm cable and I had the correct colour from a spare second door loom that I had during the door speaker part of this project.

Decided not to put in a rear console / back seat USB BMW port. But I did put in a universal pd / usb charger. This one has up to 65 watts for USB c and 18 watts on usb b. Handy for rear passenger for charging devices and also will charge work laptop if needed. Was going through BMW TIS wiring diagrams and this is what I’ve learnt. Terminal 30b feeds all 12 volt outlets. 30b is enabled when the car is considered occupied and will run until car is either locked or will stay active for 8 -20 mins if the car is left unlocked after parked. After that it powers down. Was thinking about this as don’t want parasitic power draw from usb charger. For the rear console charger my car didn’t have a rear 12 volt outlet. In the factory wiring the rear outlet ifs piggybacked off the front hidden 12volt outlet. However with the f30 / f80 wiring looms there is almost no provisioning of wiring for accessories that went in the cars original build sheet. I needed to run wires for this. So , got some 1.5mm2 wire left over from adding the boot 12 volt outlet. Wrapped it in Tesa tape and rather than pull console apart to route I just used curtain wire to feed it from rear of console to dashboard. I popped the rear console trim down, drilled a 30 mm hole and mounted the charger. Works well for quicker charging of phone / tablets / laptop.

I wonder if the conversion it would detract the driving experience a bit. DCT is a bit more refined from SMG so you don’t get those brutal power shifts when you’re fanging it or the ability to manually blip throttle on down shift. Noticed this going from e46 M3 smg to f80 m3 dct. I thought the smg was a bit more fun.

Mate brought one of these. Best part of $240k . Remember getting a drive. These hide their weight and amazingly quick. 550 plus hp for that price ! GLWS.

Welcome Have a turbo six, although probably can’t offer any advice on the mod front. Have a cheater exhaust system which makes more noise when the exhaust flaps bypass part of the rear muffler. But to me it doesn’t sound great from the drivers seat in that mode. Owned a few of these over the years . Might be 37 years or so with BMWs. Roughly 800,000 kms of smiles ( mainly ) .Guessing this is a long way towards addiction.
