looking to upgrade my factory speakers with aftermarket infinity would like to know what size speakers will fit in front and rear door
2001 quad cab

thanks

 

I too am in need of some speakers for my truck.

 

I up graded mine about 6 months ago with infinities. I'm positive they are 6x9's in the doors and 5 1/4's behind the seat but thats in my regular cab with 4 speakers. The front doors should be the same but I dunno about the rear speakers.

 

i used infinity 3-way 6x9's in the front but i have a reg. cab too so not sure about your back speakers.... the speakers were 100x's better than stock, great mid and highs with pretty decent bass too.

 

The infinities I used were alot better than the stock ones!

 

the front can also use 6.5" in the front with an adapter thats what i did and the rear doors are 5.25" iirc

 

Where are you fellas purchasing your infinity speakers? I have the tweeters as well as front and rear doors and I would like to upgrade as well.

I know the front doors on my reg cab dually were 6X9, and the speakers behind the seats were 5 1/2. I would think they are the same for a ext cab, just in the doors instead of behind the seat.

 

Check with Crutchfield. They have always listed correct size for my various vehicles. They have good service but be sure to price check.

 

Thanks guys, my tweeter and door speaker went out me. So I need some speakers. I too would like to know where to find the tweeters.

 

i got mine from best buy

 

They sell the tweeters there? I'm thinking the tweeters might be dealer only....maybe?

 

Nope, Crutchfield is wrong on our trucks. They call out the 5 1/4" for the front speakers IIRC. I have even sent an email to tech support to correct it, but they haven't fixed it yet.

The quad cabs have the 6x9 in the front, and 6.5 in the rear.

 

thanks guys
the front door looks like it can take a bigger speaker was it hard to remove the door panels how many clips did you break

 

Its not how many will break but how tight they fit after you try to reuse them. Best bet is to replace the clips.
I put 6x9 in front and 6.5 in rear doors.

 

thanks guys
