2 OHM speakers?

[RL Lemke]

My son turned the bass all the way up, then the volume, then played Rap crap. Now my front door JBL speakers rumble like they are torn.

I went to Best Buy to get replacement, higher quality speakers and was told that their 4 & 8 ohm speakers would not work well with the JBL 2 ohm system.

What is the collective wisdom regarding replacing the door speakers?

Also, the cut-out area in the door looks as if the speakers are 6x9 in size. Yet, Crutchfield also shows 6.5" speakers for the door. Which size is an easy replacement?

I found this write-up about the issue:

Impedance, most car audio speakers are 4 ohms, most home speakers are 8 ohms. The reason car speakers are usually 4 ohms is because in the early days of car audio it was difficult for amp designers (or powered radio designers) to make much power from the measly 12 volts the car has to offer from the battery. So they by using 4 ohm speakers the amps make more power with less battery voltage. Now there is starting to be a push toward the 2 ohm capable amplifiers for even more available power. Check your amplifiers rating to see what impedance the amplifier will be happy with, and buy speakers that have he recommended impedance. Running a speaker with an impedance less than your amplifiers specs recommend will give you more output power at the speaker but may damage your amplifier from the added heat caused by increase in current caused by the lower impedance, do so at your own risk...

Yah but you wanted to use a higher impedance speaker. That should work albeit likely with reduced volume. If you want to stick with your stock system there might be people around here who have replaced theirs and could sell you what you need -- though I thought I read somewhere that the front speakers basically have to be destroyed to be removed from the door???
