you really dont need the instructions. I would suggest NOT using them for the back. unless all you like to listen to is treble then it is going to sound like sh*t

I was just going to order them saying it is for the rear so I can get the GM speaker adapter plugs. I think I need those for the front to install them, correct? If I order it saying that it is for the front, I don't get any accessories.

Like I said before, I have new 6x9 5-ways for the back.

you will get the speaker adapter plugs whether u order them for the front or the rear....

Incidentally, Crutchfield'* "fit guide" is notoriously bad for our Bonnevilles. Although Crutchfield is generally great for other car audio things, especially installation kits and instructions. But I think you can do way better than to just trust whatever a Crutchfield rep on the phone tells you will fit or not.

My Bonneville SE came from the factory with no rear speakers, so I didn't have the plastic mounting rings that the factory 6x9 speakers attach to. Crutchfield phone guy told me I needed these:

Short version: No, those won't go in our cars. You can see the one that does if you scroll that page down a bit, and also on page 2 of this thread that chronicled my install:

My 6x9 Boston Acoustics speakers did not fit into the stock plastic mounting ring, because the metal speaker basket was slightly wider than the hole in our plastic mounting rings. This might be along the lines of what your Crutchfield rep was saying. Although ten minutes with a Dremel tool widened the opening so my BA'* dropped right in.

I wouldn't put round speakers in the back where you have oval 6x9 openings, when you can just get 6x9 speakers in the first place. Doesn't seem to be any critical need to put a smaller round speaker in an oval hole.

I got the front speakers and a new headunit today in the mail. I'll hook it up and see if the Pioneers fit up front tomorrow. You guys better be right :P

On a side note, I ordered the speakers from the Scratch and Dent section, and I see nothing wrong with them. Also ordered the headunit from Outlet and it seems fine too. ~$50 savings doing it this way.

One reason to put a matched rear speaker in with the front it to match the "voice" of the speakers. Many people will run a component set up front and a matching midbass in the back for rear fill.

Round speakers will have slightly higher sound quality then an oval or square driver too. The cone will flex less, and the output of sound is more uniform. Noticable in the common application? probably not, but if you have subs, there'* no need for extreme lows from the rear speakers.

I put the 5.25'* in the front doors and they fit fine. Crutchfield knows a lot, but not everything.

Also installed the 6x9'* and the new headunit. iPod adapter coming soon!
