ninjaturtlesM35x Posted July 15, 2009 Share Posted July 15, 2009 i couldnt find any sub install's on harman kardon cars. i dont know much about systems iether. i do know that open air subs suck. i know that with the same power a sub in a box would do allot better. anyone know if/how i could just put a new sub and box attached to the stock wiring? i dont need allot more knock.

jeepr Posted July 16, 2009 Share Posted July 16, 2009 That's strange, because if you look at the Subaru website and go to the Legacy and then features & Specs and interior, they say "9-speaker Harman/Kardon® audio system with 7-channel amplifier/equalizer, subwoofer". And there is a picture with red marks of the locations of things: speakers in doors, something under passenger seat (which I think is the amp) and something in the back deck, which I assumed is the subwoofer.

Chad W Posted July 16, 2009 Share Posted July 16, 2009 The sub is installed in the rear deck. It's a weird design and really has almost no out put. It can be easily replaced with a typical 8" woofer that is less 3"3/4 and has a 4 or 8 screw pattern. If you wanted to replace it with a sub in a box you'll want to make sure that it's 2 ohm (parallel 4 ohm voices coils on a DVC) and has a high efficiency rating, or it won't make enough sound to get out of the trunk. Keep in mind that infinite baffle can be great, if well selected and baffled. Also they don't need much power to be effective. Link to comment Share on other sites More sharing options...
bravonoj Posted August 3, 2009 Share Posted August 3, 2009 Chad, would it be safe to say that the 8" HK Sub would be easily replaceable with one of the Pioneer 8" shallow subs (2.5 inch mounting depth), or even one of the Dynaudio Midbass drivers? Would it be just a matter of tapping into the stock wiring? thanks! Link to comment Share on other sites More sharing options...
Chad W Posted August 3, 2009 Share Posted August 3, 2009 I think the pioneer would work, but I think that has a 6 hole pattern which means that you may need to add mounting holes. If you pull out the sub there is also a 1/4 thick metal plate that the sub mounts to. If you pull the sub out and separate it from the plate, you can use that a guide to would drop right in. You could also use a grinder to open the plate up to accept any subs that are a bit on the wide side. Right now I'm keeping my eyes out for a old JL IB84.

RIPjeep2002 Posted August 6, 2009 Share Posted August 6, 2009 Let us know. I am looking into taking out the HK thingy, and put in a small 8" sub that can be run off the stock amp. Anyone else find any shallow subs that can work? Link to comment Share on other sites More sharing options...
ninjaturtlesM35x Posted August 7, 2009 Author Share Posted August 7, 2009 I have nothing constructive to add to this thread, but I just wanted to point out that the OP has an awesome username. THANKS MAN i dont really care if the sub is shalow or mounts. i didnt want to replace it with another open air. i would idealy like to put a conventional sub in the back and use the hole for the stock sub as a port or something.

bravonoj Posted August 7, 2009 Share Posted August 7, 2009 on the same note, if you were to do a sealed box in the trunk, note that with the sedan, the HK Amplifier has 2 sub outputs; the outback uses both, the sedan only uses one - thats another set of power for a DVC Sub in a sealed box - just a thought.....

Chad W Posted August 7, 2009 Share Posted August 7, 2009 When I get a chance I'm going to try to tap into the second output and put it on my subs other voice coil. Ideally a sub with dual 2 ohm voice coils could maximize the output from the amp. Also, it is possible, though I have no way of knowing other than to try, that the channels could be bridged to a single four ohm voice coils.

ninjaturtlesM35x Posted August 8, 2009 Author Share Posted August 8, 2009 wow.. why is that? does the wagon use a different sub? excuse me if this information is already out there. how much power is there available to run a box off the stock wiring? Link to comment Share on other sites More sharing options...
Chad W Posted August 8, 2009 Share Posted August 8, 2009 Wagon uses a larger dual voice coil sub. There is definitely enough power to run a regular sub off the stock amp, just look for something with max efficiency, not maximum power handling.

bravonoj Posted August 9, 2009 Share Posted August 9, 2009 dont know if I posted this yet but my newly replaced HK Stock sub has also started to make whistling noises when only turned up halfway. I have left a message with my dealer to order a replacement, if the new one also exhibits issues like the last two, then I am going the aftermarket route and will try the Pioneer 8" shallow sub and see how that works out.

Chad W Posted August 10, 2009 Share Posted August 10, 2009 BTW this is what I have in there now: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=290-357 It's a decent improvement, but not ideal for use with the stock amp, because it can only be run at 4 ohms , not 2.

Chad W Posted November 20, 2009 Share Posted November 20, 2009 Rear deck removal isn't hard, just take your time. Search around, I think I've seen a tutorial on here once or twice. Link to comment Share on other sites More sharing options...
markc0220k Posted November 20, 2009 Share Posted November 20, 2009 i did search and i'm still searching it (both audio and walkthru section), but couldn't find it. my sub is coming next week. Link to comment Share on other sites More sharing options...
Chad W Posted November 22, 2009 Share Posted November 22, 2009 I don't remember where I saw it... Do you have any experience with audio/interior work? I would just say to take your time and don't force anything. You need to remove the parts of the rear seat on the side that don't fold down. They are held in with a bolt on the bottom.

bravonoj Posted December 2, 2009 Share Posted December 2, 2009 try emailing or calling Crutchfield. They have terrific detailed instructions on teardowns for car audio. I think they might even email it to you but you may have to pay 4.00 or so for the "handling" but well worth it if it is a hard to remove item.
