    upgraded speakers, no amp?

    I recently added a new Alpine deck to my car, and it carries the standard 50x4 internal amp. From the last car, I've got some nice Boston speakers (FS60 front, RX47 rear) that I'd like to add to the car, but I don't want to mess with the amps yet.

    Will the speakers sound any better than the stock (non-upgraded) ones on the Alpine internal amp? Will they even work? Boston says that the FS60s take 15-150 watts, and the RX47s take 12-120 watts.

    If I go that route, will I end up just unplugging the stockers and plugging the Bostons in? I know the front has the X-over, but beside that.

    Also, will the FS60 fit without moving the window rail? I've got the mounting brackets from the old car, but I don't know what they had to do to make it work.

    First off, what size are the bostons? Front/rear sizes. 5-1/4" or 6-1/2" will fit up front while only 5-1/4" will fit in the rear. More than likely your old brackets won't work with the door panels and new ones will have to be bought/made. IA performance makes a great set of spacers. You can email them with the mounting depth for the bostons and they'll tell you if it will work.

    Also, the frpnt speakers dont have a crossover...the tweeter just has a filter capacitor.

    6.5" up front, 4" in back.

    Why wouldn't the brackets work? They're from the last car (a '04 WRX Sedan) I had these speakers in.

    Oh, I didn't know the brackets were from a WRX. So then 4" would work in the rear as well.

    The rear should have no clearance problem. Only thing to worry about on the front is the plastic tab on the backside of the window. Easiest thing to do would be to take off passenger side front door panel (~4 min), undo the speaker and bracket (~2min) and install your new speaker and bracket (~2min). Then see if the window will roll down all the way. Remember to use short taps of the down button do if anything does rub, it will not break. If the speaker does rub on the tab, it can be shaved off.

    Anything would be better than the stock paper cone speakers IMO.

    Right, see, I know that it can be done (these were in my old WRX). The question is, does anyone know if it will need to be done? I don't want to spend the time ripping my door open and stuff only to find out I need to take it to a shop (which I will if the window rail needs work).

    I don't know how oftten I've replied to this exact same topic.

    The best location/option for aftermarket speakers is to mount directly against the door panel, aka the plastic, not the door itself. You need to seal the speaker with a little foam and then dynamat to create a seal. Use the grill/mount to create a space between the door and speaker to prevent the cone from rubbing against the door panel and then, once it's alll done, re-install the panel and see if it rubs against the window. Either way, even if you end up taking it to a shop, you'll have saved a lot of money by doing this part yourself, rather than paying someone (like me) to do it.
    Those fools, EVO vs. STi??? That's like comparing ....wait a minute...there's no comparison. The Suby's still working!!! The evo...well... I hope he got the extended warranty.

    Ok, now, I know you've installed this speaker into this door

    I need a diagram or something to get that. Mount the speaker into the door panel where the stock speaker went, and seal it in with some foam or something?

    The speaker is mounted directly against the back of the panel, then sealed. once accomplished, the panel is placed back onto the door to see if the window rail will need to be spaced out.
