Boston Acoustics SPZ60 fronts - what to use for rears?

2736 Views 5 Replies 4 Participants Last post by  DblHelix
Buying top of the line fronts but I don't know what to match in the rear. Some forums say "all 4 must match" others "rears are almost unimportant" just filler sound.

I don't want to waste money yet I don't to degrade the sound of the fronts.

What would be the least expensive model that I could use as rears and still get a good match to the fronts?

Is there a rule of thumb that can be used on rears in conjunction with fronts?

dont use anything in the rear. what are you using to power the fronts? is the door sound deadened? front stage is what matters.
I was just going to Dynmat the speaker not the entire door.

I will be using an Alpine 9887 head unit with amp yet to be determined.

I still feel that I need some 'fill' speakers for the backs but nothing like the SPZ or even the Pro. But I want something for the rear passengers.

Are you are suggesting, Dynmat the entire front doors and put whatever in the rears?

Could I then purchase a 2 channel amp for the SPZ then run the rears off the 14watts from the head unit? What amp would you suggest and how much power?

Thanks for the response.

I have 4 Boston SL80's in my truck... Love 'em...

Enjoy your SPZ60's....
rears are 6x9 correct?

these are pretty good

these too

I would deaden the whole door. 2 layers on the inner and outter door skin. dynamat is decent stuff but there's better stuff out there for the money, such as raamat and second skin.


1 roll of raamat bxt should be enough for the front doors and rear deck.

As far as an amp goes, i'd amp all 4 if your certain you need rear fill.

mb quart dsc 4125 has been getting some good reviews over @ diyma.

amp does [email protected] ohms so it'll more than enough for all 4 speakers.

only cost 120, too.

I am running the SPZ60s in my Scion tC and they are definitely a nice sounding speaker.

The rest of my equipment right now includes:

Alpine CDA-9887

JL Audio HD600/4

Image Dynamics IDQ15 sub sealed

I will be swapping out the SPZ60s in the near future to go 3-way active up front and will be adding a 2nd sub and the proper amps to do all of this.

Also, if you care about sound don't run rear speakers, they just pull your soundstage back.
