I just bought 2 Alpine MRV-1505's. Each one will be dedicated to one 12" L7. The only problem is that the L7's are dual 4's and the amp specs don't list whether the amp can handle a 2 ohm load in bridged mode. I didn't know if they don't list any any RMS ratings with anything over .3% THD or it just can't handle the load. It's an older amp so I'm hoping some of you have had experience with them before.

My wife will never understand why, lucky for her!

Not likely. I know of not even ONE Alpine amp that was ever one ohm stable... looks like 4 ohms per channel is what you're stuck with!...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

It is rated to handle a 2ohm load per channel in stereo mode. I'm not looking for 1 ohm stable, just 2 ohm in bridged.

Two ohm bridged *IS* one ohm stable... It ain't gonna work!

You kept the receipt, right? Take them back and get 2-ohm stable mono block amps instead.
