I know this should be in the audio forum, but there is a whole lot of NO traffic there, plus I wasnt sure if any other volvos shared the same stereo as the R's.<br>First I have an 04 SR with the HU-803 sound system, and am planning to do a sub install of two 10 inch JL Audi W3 subwoofers custom mounted in the sides of the trunk (so they dont take up space) and I was wondering how difficult it is to do the wiring for these cars. The boxes will be made by a professional, but I can save like 400-500 dollars by doing the wiring myself, my brother has wired cars before, but I am a little hesitant. Any thoughts?

Line out converter wired into rear subs on decklid there is your audio signal for the amp.<p>Battery is in trunk, power goes to that, ground someone on frame. Remote turn on is available in drivers side fuse/relay panel as apart of the towing/wiring option. Car turns on, as will your amplifier. <p>Thats about it.

yea that seems awfully simple, maybe the shop doesn't realize that the battery is in the trunk. If it really is that simple, ill do it myself to save $50! I'll ask the shop tomorrow or something, but seriously, to build the boxes and install everything costs a freakin arm and two legs!! my eyes almost fell out when I saw the quote, luckily most of it is a birthday gift woot woot!

does using the line out converter in the rear deck lose any of the bass sound? my brother thought you might lose some of the sound quality because "its not meant for a subwoofer, but rather the rear deck speakers"? maybe i misunderstood him.... would there be benefits to wiring to the HU?

Re: (chinaonnitrous1)

I have not been thrilled with the way the sub sounds from the rear speakers... especially w/ one of the optional settings (3ch/dolby), the bass does not hit when it should...<p>Folks have suggested tapping the line out for the front speakers from the amp under the pass. seat. Power/signal are found in the back as others have mentioned.<p>Just curious, which fuse did you folks tap exactly? I actually hit up the Haldex fuse for my 07, but if I turn the car off and pop the trunk, the sub does some funky stuff (think PWM through a 10" 800W sub <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0">)

Re: doing a sub install myself? (2004volvos60R)

I have also been researching putting a sub in my R and i came across this: <A HREF="http://cgi.ebay.com/ebaymotors/Volvo-Stereo-Radio-Factory-HU-to-Aftermarket-Amp-Cable_W0QQcmdZViewItemQQ_trkparmsZ72Q3a1205Q7c66Q3a2Q7c65Q3a12Q7c39Q3a1Q7c240Q3a1318Q7c301Q3a1Q7c293Q3a1Q7c294Q3a50QQ_trksidZp3286Q2ec0Q2em14QQhashZitem200311116936QQitemZ200311116936QQptZCarQ5fElectronicsQ5fInstallation" TARGET="_blank">http://cgi.ebay.com/ebaymotors...ation</A> it is a rca cable that is made with a DIN cable in. i have not taken the radio out of an R in a long time at work but i thought i would post this maybe someone else knows seems like a good option to the line converter <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Re: doing a sub install myself? (97GLTbrick)

I have a straight tap off of my rear speakers into a mono sub. The bass knob is generally a 'hair' up from being turned all the way down for me. It is impossible to tune the HU850 <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/mad.gif" BORDER="0"><p>No EQ, just two or three knobs - WTF!<p>I've been toying around with the gain/loudness/freq. for a long time now and it just does not want to be in that 'good' range... It's livable, but my discerning ears know better.

If you're replacing all the speakers and adding your own amp then that would be the cable to use if keeping factory head unit.

Re: (97GLTbrick)

The LOC isn't really that bad of an option. With quality parts (LOC, amp, sub, etc) you can integrate it into the system with good results. Just turn the bass on the deck down a bit so you don't strain the cabin speakers and adjust the amp to compensate. I've done it many times (granted not with an R) with much success.

so to clarify, a line out converter is the only option since I am not replacing the HU? whether its taken at the rear deck, amp under the passenger seats, or front speakers, its the only way to integrate it?
