There is a flaw here, if you have a dvc woofer that is dvc 2 ohm, you can only get a 1 ohm or 4 ohm total ending resistance, if it is 4 ohm dvc, the ony options are 2 ohm or 8 ohm ending resitance, so what is your sub?

dwarren is right. Something is wrong. 4 ohms bridged is 4 ohms. You likely had your Kenwood wired at 4 ohms. When bridged to mono your stereo amplifier may have -behaved- like it was wired at 2 ohms; but the speaker load was still 4 ohms.

You are likely running into problems because you bought too large an amplifier for your alternator. Look into buying a new alternator if you must have 1000w.

I personally see absolutely zero reason to need a 1000w amplifier unless you plan to compete. You do realize you're only gaining 3db over running a 500 watt amplifier, right? 3db is small.
