beadgc23 Posted March 15, 2009 Report Share Posted March 15, 2009 I'm planning to install BA Components (front door) & Coaxials in a V70 T5, but I don't necessarily want to destroy the original speakers to do it - they're all working! I've noticed that there are several UK sources for adapters for fitting aftermarket speakers, but zilch over here. Has anyone come across a US source? Or alternatively, want to sell me a dead/dying set of original speakers to cannibalize? Link to comment Share on other sites More sharing options...

This was for the 850's, but I believe there was one for yours as well.Thinking about giving it a try. Want to go 6.5" in the rears and 5.25" up front with the bass link in the cargo hold.lol Link to comment Share on other sites More sharing options...

There's a company called "BlueSpot" that do a set for c$50 + shipping, that may be the way to go. I'm surprised that no-one in the US deals with them.Just can't handle the idea of hacking perfectly good speakers apart when someone may need them!I'm planning to go 5 channel amp + low profile sub in the tyre well...trading skills with a fiberglass fabricator. Not looking for boom, but I'm a sound engineer in another life and the stock speakers are beginning to seriously bug me, especially those dash tweeters.

beadgc23 Posted March 16, 2009 Author Report Share Posted March 16, 2009 Problem sorta solved - I spent today installing an old pair of Boston RC620's in the front doors and dash, temporarily connected to the head (sc-816) until I get my amp organized. They were a perfect fit - the stock speakers are attached with glue & 4 catches to the standoff, and once the adhesion was broken I was able to rotate them off the mounts and screw the Boston component Midbass drivers onto them. They are 6.5" drivers with a 2.5/8ths mounting depth for reference - any deeper and they wouldn't have fitted. Tweeters went into the stock dash mounts once the volvo tweeters were unsoldered, I'm going to fabricate plates out of plastic to hold them. Neither the 6.5 volvo drivers or tweets were damaged during this process! Door panels were treated with Video Gaffers tape (I've always found this to be superb at killing resonances, and a steal at $20 a roll. Doesn't smell, either...) Everything looks 100% stock, my secondary goal.The Boston crossovers were quite bulky, but were eventually slotted in to the right of the head unit, up against the left hand side of the glove box and held there with adhesive velcro strips.I didn't replace the factory wiring - it looks like 18 ga cable which is more than ample for a run of this length (I'll spare you the math - 18 ga is fine for 4 ohm speakers up to 35-40ft or so). There's some incredible garbage propounded about speaker cable and I'd invite you to google "speaker cable myth" if you'd like to know what real audio engineers think about it. Suffice it to say that Monster and their ilk have pulled a Bose-style marketing scam on the audio buying public, and I'm quite sure that if I'd been talked into spending $500+ on speaker cable for my home theater I'd be VERY motivated to hear a difference. Rant off!I fiddled around a bit with connections, and found that the HU was quite happy with the xover/6.5's/tweets paralleled off of the L&R door speaker outputs (approx 6 ohm load as I calculate) Overall, the volume level was a little lower than stock (RC620 has an efficiency rating of 90dB at 1W) and dynamics are what you'd expect from a low current HU, but having said that, speech reproduction is excellent. I've always found (I'm a sound engineer BTW) that if speakers can reproduce speech well, then everything else above 90 Hz or so is probably going to sound good too. Bass is sensibly attenuated below 70-80 Hz, leave that for the subwoofer.I may not bother with the rear doors, but concentrate on the amp & sub. I should stress that I'm looking for a system that plays absorbing music and that allows me to assess my recordings while I'm on the road - I'm sure that the SPL junkies would have different priorities.

Black 850 Posted March 16, 2009 Report Share Posted March 16, 2009 I am interested in a similar project for my 850 wagon. Print as much info as you can.Thanks - David. Link to comment Share on other sites More sharing options...
beadgc23 Posted March 17, 2009 Author Report Share Posted March 17, 2009 The speaker sizes are different, that I know (51/4 fronts in an 850). Search around, there's way more on 850 installs than V70's. I can say that the factory speakers have a lot more boomy bass than aftermarket units IMHO, so if you're not going to install a sub right away you may want to consider leaving the rear door speakers in place for a while as a stopgap. Oh, and the rear pillar tweets really mess up the soundstage - disconnect them!Downside of quality components - now I can hear exactly how lo-fi my favorite podcasts sound.
