That seems like a lot of effort to go to just to listen to The Archers?

Not sold on losing boot space to a speaker (unless you can open the boot and use the bass for an extra 20bhp of boost), but I do agree that replacing the interior speakers with something less primitive (and lining the doors with dynomat) can only be a good thing.

Seriously the boots are huge and the sub box is like 8" square it looks really funny in there as its so small! I'd loved to have put the sub in the car (glove box area but that's full, as is behind the dash) or above the wheel arch area (the void that is rarely useable) but that would require a lot more work!

Oh how I'm enjoying the new audio... It wasn't all that bad before but is so much better now. Below are the OEM speakers the mids are rated at 30W and the tweeters at 20W for anyone interested.

 

So I visited Mark and the team at Oxford Car Audio (OCA), it was really funny (probably not for them) when I arrived their alarm was going crazy and they couldn't switch it off (alarms hey, who actually hears them and does anything!). 

 

Having discussed different options over the phone and email I was unsure exactly which route to go...

 

In the end I went for JL Audio C3-650's in the front doors.

Sound deadened the inner and outer door skins and went with MDF rings in factory placement.

I already had a few amps (I'll come back to those later!) but I wanted this to sound fantastic, I'm getting older, have two children and lots of other things going on so this needed to be a place I can enjoy. To help with that OCA supplied me with an Audison BIT 10D. Having had the old kit fitted very poorly by a mobile fitter local to me I didn't want anything to whine or go wrong, the BIT 10  has a time on/off delay so there is no popping as the car checks what speakers are there and functioning - these skoda are clever! It also use high level inputs from the RNS 315 Amundsen+ Nav and does this de-equalisation thing, it then lets me control each speaker (both tweeters, mids and sub) individually for crossover points, time alignment, levels and a 31 band eq... It's like having an audio mixing desk in your car! I'd highly recommend the Audison Bit10d!

 

To power each speaker I had a few old amps that I'd bought over the years. An old Alpine MRV-F340 powers the fronts, its a four channel amp so a channel per speaker, I was hoping to use my first and well loved Rockford Fosgate Punch 120a2 to power my alpine 8" sub but all the years sat in my garage hadn't been kind so so when we powered everything up it sounded aweful so out came a new Alpine MRV-M500 - a completely over powering amp for the sub but leaves loads of headroom and opportunity to upgrade my sub if I ever want to in the future (not that I can see when I'll be able to afford it or need to, the 8" sounds sweet).  

 

So it's all in and sounds good but I think I'll be spending hours if not days tweaking it to perfection...

 

I need to head back to OCA to get a couple of little things sorted (the controller for the bit10 keeps falling down and I want to check a few settings) otherwise great job and really friendly team, I just wish it wasn't an hour away!!!

Hi how did you connect sub to back of unit thanks

So Oxford car audio did an awesome job. They took the high-level signal from the headunit (rns315)  to the audison bit 10d (dsp), which then de-eqs the factory signal sends the time corrected/eq'd signal to the amps, using rca cable running each speaker active :)

 I'm (still) planning on doing something very similar - it's the clever bit on the stereo that scares me. Does it throw warnings with the Bit10d?? Did you have them coded out? 

I was planning on getting on the stereo this week, but had given up with lockdown as I wouldn't be able to travel to a coder...

Carista throws up a fault code but nothing visually.

Found the Bit 10 on amazon for £210, so now ordered... build may have to wait until I've got time off in September, though 😞

Install (or not install, yet!) going on here: 

 

anyone know where i can ge the code for the columbus radio?
