I have a 98 Z i am assuming I have a monsoon system. I replaced the HU with a Pineer premier, and I want to change the front 4 speakers ( 2 in door , 2 in back seat pillars) the 2 speakers in the hatch are in good shape still. Ive heard the stock speakers have a 2 ohm load, and most aftermarkets have 4 ohm load, how can I installed aftermarket speakers without losing half the power though the extra 2 ohm load?

If you use a 4 ohm speaker in the front doors with the Moonsoon system, the
sound output from the 4 ohm speakers
will be less than the 2 ohm speakers so
when you turn up the volume, especially
bass driven music, you stand an excellent
chance of pushing the amplifier into
"clipping"....clipping will damage the
speakers sufficant to require their
replacement.
Either go with the OEM 2 ohm Delco
or get a different amplifier friendly to
4ohm speakers.

check that Ls1tech theread, and the otehr sticky theread there. A LOT of us have been running 4 ohm speakers to great success,

THANKS ALL
