Starting a thread to document the audio install of my new to me, 2015 V60 R-Design. Prior to this I had a 2006 Audi A4 Avant, all of the audio equipment was previously installed in the Audi and I hope to use it all again in the Volvo.
I plan to do a few cosmetic mods to the car, but nothing much as I am very happy with the look of the car, will just tint the windows, maybe lower it around an inch and add some wheel spacers.
The car came stock with the "Volvo High Performance" system, which is 3 way in the front doors, what I assume to be coaxial in the rear doors and a center speaker. I read somewhere that the High Performance system was 12 speakers, but I can only identify 9 (3 per front door, 1 per rear door and center). Not that it matters, the front door speakers will be replaced with Scanspeak tweeters, Infinity Kappa 20MX mids and Stereo Integrity TM65 MK2 for midbass, rear doors will simply be disconnected (although if I can figure out how to mount a pair of small speakers in the D-pillars, then I will use the MiniDSP to run differential rear fill). The subwoofer will be a Stereo Integrity SQL12 (not pictured):
Amplification will be an Alpine PDX V9 (sub, midbass and mids) and a PDX V4 (tweeters and hopefully rear fill). Processing is via a MiniDSP 8x12 with Dirac Live. I have had the MiniDSP for around 2 years now and upgraded the firmware to run Dirac Live last summer, adding Dirac was a game changer in the Audi. Where previously tuning was manual tweak, listen, measure, tweak, measure, listen etc. for hours on end, with Dirac I enter my crossovers, take 9 measurements and load whatever house curve I want, the software then automatically adjusts everything needed to match the target. I can go from having no tune to a decent sounding tune in about 15 minutes. I'm watching that thread about the Android based head unit, I was spoiled with a Kenwood 9906XR in the Audi and using Android Auto was excellent, was also half wondering this morning if I could update the Sensus unit in my 2015 to the later Sensus from the 2015.5 model and later years.
Over the past weekend I decided to remove the door card to take a look at what I will be starting with, if anyone knows how to disconnect the exterior door pull from the door card please let me know. I could not figure it out and did not want to risk breaking the mechanism. I'm used to a simple hook in the Audi that just popped right out. Back to the speakers, the tweeter in the sail panel just pops off with 3 clips, grip the housing towards the front and rotate it away from the door and it will pop free. I do not have BLIS so just needed to unplug the tweeter. Replacement looks a little harder than I expected as it looks like the tweeter is somewhat sealed into the housing. In the picture below you can see the cross hatch pattern where it looks like the 2 halves were melted together. Since I don't want to demolish this, looks like I need to order some new tweeter housings:
If anyone knows how to get the tweeter out without demolishing the housing, I'm listening.
Onto the factory midrange, this is screwed to the doorcard with 3 T25 torx screws and on a little plastic mount, hopefully as long as there is enough depth (99% sure there is) then I can simply make my own mounting plate and install the 20MX in this location:
The midbass is mounted to the door itself, again with just 3 T25 torx screws, located directly beneath the mid. Looks like plenty of depth to mount the TM65's so no major concerns there:
Here's where things get a little confusing, at least for me, hoping some of you more familiar with Volvo's can help. So, the molex plug boot is in a sort of Z shape, getting 3 sets of wire through is going to be a massive headache first because there is little room between the door and the body and second because fishing 3 sets of wire through that boot will be problematic to say the least. Because of this I had hoped to tap into the stock speaker wiring inside the car and utilize the existing wire through the boot, I don't run huge amounts of power, so the stock wire should be fine for me and I will just splice my own wire into it inside the kick panel. But, at the moment I cannot figure out how it's wired (not yet pulled the molex plug, hoping I can get lucky). So, here is the wiring for the tweeter and mid:
The wires are the exact same color, even the plugs are identical. Here's the wiring going to the midbass:
4 wires, no clue why. I am going to try to find some wiring diagrams, hopefully that sheds some light on things and ideally I can use existing wire through the molex. Once I figure that out and can determine how to get a power wire from the battery to the trunk, I plan to remove the passengers seat to tap into the signal there to feed into the DSP which (along with the amps) will be located under the floor in the trunk). In the Audi I had a subwoofer mounted inside a suitcase, while it looked very stealthy and I got many compliments on it, it took up more cargo room than I am willing to sacrifice. The SQL12 will fit in a sealed enclosure from 0.8 - 1cf, which is OK for a subwoofer of that capability.
Last picture is a quick measurement with REW of the stock system, all the EQ is flat (has a 5 band in the head unit). In all honesty, it does not sound that bad other than the complete lack of anything below 35Hz.
If I did not already have all the equipment and plan to compete with the Volvo, I would be seriously tempted to just add a subwoofer and call it a day. I'd be lying if the thought has not crossed my mind, however one of my biggest complaints with the stock sound is that it does not get that loud and is missing some of the dynamics that you get with a really well set up system. It's good for what it is, but coming from what I was used to in the Audi, it's lacking.
Over the next few weeks I plan to pick up some of the supplies I will need, power cable, speaker wire, sound deadening etc. and get started. In the meantime, if anyone knows anything about that tweeter housing, disconnecting the door pull from the door card or getting wire through the boot/molex into the door, please let me know!
