1990 Sierra 1500 Speaker specs

TrAvIs 05 · September 29, 2005

I just got a new CD player and it works great but the speakers SUCK. I need to get new ones but i need to know how many to get, what size(s), and where they are all located.

Does anyone know if Sony Xplod "4x6" speakers will fit? If not will these Pioneers fit right?

Yup, either set should fit fine.

They ought to fit good. There are four speakers, two in the dash and two just at the corners of the seat in the plastic panel that goes up onto the headliner. That panel is a pain in the *ss to remove. You have to take out all the jack storage housing and then go after the screws because it's kind of shingled in there. And there are these annoying clips that you don't want to break.

You can do it, it's not so hard, but be VERY patient and have a few skinny flat screwdrivers around. There are more clips on that dang piece of plastic than you can count.

One thing, the benefits of better sound will be WELL worth it. Just take your time.

Don't do this:

That kind of depends on the trim level. If it's a W/T or Cheyenne, then there could only be a couple of small grills covering the speaker holes. Those come off in about 8 seconds with no tools.

Xplods dont fit. I just went and bought some 4x6's at Walmart and the magnet is really big and it like sticks half an inch out of the dash hole. I'm getting the Pioneers today and if they fit in the dash then i'll go through and do the panel ones too.

Yeah, the xplods from the top of the speaker to the bottom of the magnet are bigger than the stock ones. The speaker hole in the dash aren't deep enough. Even with the little spacer that comes with it it still doesnt fit.

Also, i have to take off the seat belt to get those panels off don't i?

Yeah, if you have those panels, I'm pretty sure the belts have to come off.

You might want to look at plates. They sound a bit better if amplified, but they can do fine off just a head unit and give a bit more room for mounting.

If memory serves, there is more room on one end of the holes in the dash, and the bigger end of the plate can be swapped into the deeper part if need be.

I've used Boston Acoustics 4 x 6s as well as Infinity plates in the dash of my '92, which should be identical to yours.

The rear speaker holes should accomodate just about any speaker you want to put back there...Nothing but empty space behind there. Lots of room.

Ok, can i splice speaker wires or do i NEED adapter(s) and stuff? Here's pics:

The wires from the old speakers are light green and dark green and they don't have lines or anything on them so i don't know which ones positive or negative and the wires that came with the Pioneer speakers one set is white and one set is gray and one on each set has a line on it and the other doesn't. How do i know which ones connect to which because there aren't any instructions with them. The plastic thing don't fit onto the new speakers so is it possible for me to just cut and strip the old wires and splice them to the new ones and just clip the new ones onto the speaker?

Ok, so i spliced the front and they work now but i have no idea how to get to the back ones. I took out all the jack parts but i can't remove the bottom part of the storage thing i have no clue how to do it. Also, i don't think i have a tool to take off the seat belts either.
