2000 Z3 "behind-the-seat" speaker

I know most everyone says just disconnect them but if I were to replace them anybody have a recommendation?
They are the 4" speakers w the "U" shaped grill

Are you keeping the stock HK amp as well, or upgrading it?

Upgrading the whole system:
Alpine CDE-143BT head unit
Alpine MRV-F300 amp
Polk kicker & tweeter speakers.
Kicker 10CVT65 subwoofer

So I was looking at just doing the whole thing & replacing the 4" behind the seats.
Don't want to spend a lot, keep it under $70

That amp won't support the additional speakers behind the seat. It has 4 channels, but you have a subwoofer.

You will use 2 channels to drive the front component speakers and you will bridge the other 2 channels to drive the subwoofer. That will give you 2 50-watt channels and 1 100-watt channel for the subwoofer. The Kicker can handle 150 watts, so you're a little under-powered there.

See Figure 12 of the Owner's manual:

Doesn't the head unit push anything?
What about keepin the stock amp to push the sub?

Looks more & more like I'm just gonna DC those speakers

Sure. I wasn't considering using the head unit to drive the behind-the-seats speakers. I actually had mine set up that way for a while, but decided that those speakers just added noise rather than fill. So I just disconnected them and I think my system sounds better.

You can replace the 3-inch speakers, but it's tricky. You won't find any speakers with the giant ring mount so you will need some type of surface mount that will take away some seat room, especially if you have the seat-tilt mod installed. Personally, I don't like the look of any aftermarket speakers I've seen back there.

This article offers a great explanation of what is involved.

You know, relocating those to the door panels at around knee height would be ideal for better imaging.
A good 3 way crossover for the front channels, with bass blockers for the 6.5's in the kick panels would probably sound great if coupled with a bass improvement mod.
That could still be done with a 3 or 4 channel amp.
