Base Audio upgrade/improvements
Hi all.
My BMW base audio system is not great.I want more clarity and loudness, not huge on base. I am wanting to upgrade my system speakers ie, 2x front door speakers, 2x underseat subs with the below: 1.Vibe Optisound Bmw mids and tweeters and crossovers (I have the A-pillar trims for the tweeters) 2:H&K underseat subs 3.Vibe 4channel LOC 3.Phase Linear 4channel mosfet amplifier 4.Vibe or JBL rear panel Coaxial speakers 1.What is your opinion on these components. Will they work with the least amount of hassle. 2. The H&K subs will they be a direct replacement for my base subs and will this old school Phase linear amplifier be able to power this without issues 3.Can someone provide me supply with the colour code for the wires I would need to cut into at the radio plug for the LOC connection Many of the components listed by members here are not available in Cape Town or just cost a fortune. I have the amp, the h&k subs and tweeter covers and most of the wiring. Any advice and guidance would be greatly appreciated.[/QUOTE |

First things first, there are no magic speakers that will instantly transform your sound, no matter what the advertising says. The best value is going to be used OEM Hi-Fi or H-K speakers being sold by those who believed the advertising.

So sourcing a good used set of H-K mids and tweeters and running them via the LOC and amp is first choice. Would I need additional magical items to run them?

Ok
So HK mids and Tweeters Base audio 6.5 woofers Phase Linear 4 channel amp ( is it the 60x4 rms version? So what I’d do Run front speakers and underseat woofer off phase linear but channel 1 & 2 running door speakers and tweeters. Set Low Pass filter to around 120 hz Channel 3 & 4 running underseat woofers Set HPF at 120hz Rear speakers , no change to amplification and run off idrive. Change speakers if desired , you want 4 ohm here. Cabling Loc between L & R front speaker outputs from BMW ( assuming the Phase linear only has RCA inputs with 2 volt max ) At the moment the front underseat woofers are in line with the front speakers. The doors are connected via the woofer connector. These need to be split apart. Run phase linear L&R front to door speakers ( connector point is at underseat woofers ) Underseat woofer change. Don’t go HK with amp . Won’t produce enough power into 8 ohm. Hifi or aftermarket 4 ohm or better still two ohm if the phase linear can run two ohm. Can be done via a Technic PNP bmw base audio conversion wiring set. Alternatively aliexpress has bmw underseat woofer connectors if you’re up for building your own harness. Amp , find location like left trunk floor where factory amp is installed. Run fused power connection of suitable gauge wire to amp. You’ll also need a power on circuit. Run this to the rear fuse box. You want to find a point in the fuse box that only comes on with ignition. Get one of those fused piggy back accessories fuse. Base audio will either power the current speakers either directly from idrive or if you have ASD this wil be the amp If you have any info on the post here. https://technicpnp.com |
