    Question Can i pun an additional oem sub under driver seat? Help

    I have an 02 wrx and the next move i want to make with it is better sound. I currently have a stock, 6 CD changer hooked up to a stock OEM sub. I want to rip out the 6 CD changer, sell it, install a new head unit (for mp3 play back, frontal aux jack for top quality ipod playback, and for looks) and really want a little more bass so my idea is to install a OEM sub under my seat to give my car a little more "BUMP" and a unique audio set up.

    ****please tell me what you think, past experiences, and suggestions good or bad, i really need so ideas!


    Thank You

    You would be better off spending your money on something other than an OEM sub. I've heard good things about the Infinity Basslink, but there are many other good options out there in just about any price range.

    Really you gotta ask yourself how much "BUMP" you want your car to have. The also depends on what type of music your listening to, what door speakers you have installed and your amps. Car audio is a hobby of mine so here is what I would recommend from my personal previous set ups and my experience with installs.

    #1. The speakers in your front doors are probably THE most crucial aspect to setting up even a decent sound system. You want to go out and get a good compenent set. I recommend Focals or JL audio for top of the line stuff. If you want a step down from that go with Boston Acoustic. You also want to get an AMP that's going to either max out, or come close to maxing out the max handling voltage of the speakers you buy. NEVER OVER unless you really feel like replacing your new speakers. Your rear speakers aren't as important cause lets face it, you're the one who spends the most time in your car, not your passengers. And if you put in new back speakers then you have to get a bigger AMP and spend more money.

    #2. I'm very partial to JL Audio subs because I have used other brands like Rockford Fosgate, Alpine, Sony Xplode (if you buy it...i will personally come find you and punch you repeatedly in the face), and Panasonic. They are all sub par compared to JL. Depending on if you listen to mainly fast hard rock, rap or a mixture of both should determine on what kind of subs you get. If you listen to rap/hip hop a lot get one or two 12 inch subs depending on how much bump you want. Two 12s is a lot of bump though. Even if you listen to them in a store you wont notice how loud they really are until you get in your small enclosure we call cars and crank up the tunes. For any other applications I sugges that you go with two 10" subs. The 10" subs still give you that bump if you listen to a mixture of rock and rap and if you listen to hard fast rock the smaller diameter of the speaker is able to be pulled back faster so you get a more clear and exact sound.

    #3. Your amps are obviously important. You want to make sure you get amps that will push as close to the maximum the speakers will handle but never more. As stated in point #1. you dont want to be replacing your new speakers. Get a nice 4 channel amp for your door speakers. Depending on what subs you go with 1 or 2 channel amps can be used depending on how performance youre looking at getting. The most cost effective is just go get a 1 channel amp and if you have two subs just run an extra set of wires.

    Well thats my little blurb on car audio. If you have any questions let me know.

    Man I'm glad I have an easy job and can take 20 minutes out of my day to type this!

    Definitely want good front door speakers. What do you think about Infinity Precision Perfect or MB Quart components? I went to car toys and listened to them both, and IMHO the MB Quarts sounded MUCH better. I've also heard good things about CDT component speakers. How do you think these stack up against Focal or JL components?


    And I believe you mean you want an amp that is near the max wattage of you speakers, not volts..

    It is generally less powerful amps that damage speakers, not more powerful amps. This is -- again, generally -- because at their current limit, amps will clip. A less powerful amp is more likey to reach this limit during "normal" listening (ahem!...) than a more powerful amp.

    I'd still sell off the factory sub and talk to a specialist in your area about a discreet setup that'll better fit your music needs.

    Keep in mind if you are doing the install yourself I suggest to get some speaker spacers for the front speakers. Its very shallow. I got focals, and I love it. From my experience in the past MB quarts tend to have too much highs and lows, and not mids for vocals.

    awesome.

    Thanks a lot for all the suggestions that really helped! WHat do you think of me taking out the oem sub and replacing it with a Boss Audio BASS600 8-Inch Low Profile Amplified Subwoofer.

    Once I get the Boss Audio sub in my car I'll let you know how it sounds.

    Got it.. installed it. Sounds above and beyond what the OEM sub could do. Much louder, deeper, the response is about the same. It's not quite as clear as I would like, but I have a feeling this will sure up as the sub gets broken in.


    So I would say, with the Boss Audio sub currently costing $127 shipped brand new, the Subaru OEM unit should cost about $35-$40 brand new. Any more and you'd be wasting your money.


    Fits perfectly under the seat BTW.



    I will post up pics of the size comparison and instillation later on.




    A word to the wise. Make sure you get all the levels adjusted on this thing just how you want them BEFORE you secure it underneath the seat. It comes with a volume control remote, but it's more of an ON/OFF switch than a volume control. The gain adjustment is extremely sensitive with the 4 volt amp outputs from my head unit. Probably not so much if you're using a line converter. But none the less, you're going to want to fine tune the gain before you get it secured under the seat.

    Thanks

    I would love to see some pics of it and there is a circuit city by my house that does instillations, should i drop the car with them, with the parts or should i do it myself?

    Personally I wouldn't pay someone to do it. It took me all of a bout 30 minutes to install leisurely (not including finishing work).

    Are you working off of the factory radio, or an aftermarket HU?

    To install any additional speakers to your head unit (since it doesn't have any amp outputs) you're going to need a line level converter. You splice the desired speaker wires and wire them into the converter box. Then you plug RCA cables into that box and run them to your sub. Then all you need is power and ground cables (8 gauge or larger for this unit). And also a remote wire that comes from the HU and tells the amp when it should turn on.


    That's about it. It can be a little confusing the first time, but if you follow directions and use some DIY common sense you should have no problem hooking it up yourself.



    One consideration is that high quality audio cables don't come cheap. But I'm sure it's a lot cheaper than someone would charge you to have it done.
