Opinions on Polk Audio Speakers?

[MZ-N10]

the best plan is to follow toms suggestion and just try the speakers on the stock deck. theres alot of people on here that are car audio junkies, so hopefully they'll chime in soon.

i wouldnt suggest you changing out the rears unless you absolutely have to. the rears require you to take off most if not all the interior panels.

To me not only is the sound system a good upgrade, but the VX is waaaaay bad for speaker boxes. After upgrading my brothers 1991 celica way back in the day, I had a chance to see a real manufacturer speaker box desing. This thing had hard plastic and molded "live sound" boxes with wadding, etc. and port openings- 4" front and 6.5" rear. I ripped them out of the car when we had to part with it (died a horrible SCCA rally death with almost 300,000 miles. lol) I am attempting to turn, twist, etc them to see if I can find a way to install them in my truck.

The point is- before you even go shopping for speakers, I would research how to either dynamat, sound box, etc. the new speakers that will be installed. In the back, there is absolutely nothing for sound. Just a metal bracket to hold the speaker which is basically a freestanding, suspended, open-air speaker setup. Even if you did a sound setup before aftermarket install, you would have better sound, and would only have to trim slightly for a deeper, slightly larger diameter aftermarket speaker. I personally hack- sawed the rear metal bracket in two pieces vs. one so I could have 4 6.5". In the front, the tweeters are fine, but the thin plastic/thin metal door with no box leaves much to be desired as far as a place to mount the bottom speaker.

Oh yeah, good luck if you decide to do the rear. My advice- whatever you do, do it all at once, and schedule plenty of time for the job.
