by NSXS: Correcto-mundo. In most cases (I've seen) with good-quality car amps you'll only get about 3 times the output power because of increased losses through wiring (internal and external to the amp) and some power supply sag when it tries to supply the extra current. You'll usually get more power by bridging at 4 ohms than by straight amp with 2 ohms, unless you're going to use two drivers with the straight setup. I always had room for the amps but not the extra drivers, so I preferred bridged.

Years (and I mean years ) ago, (before bridged amps were around) I used an op-amp inverter to invert one input of a stereo amp to achieve the same effect. Should have marketed that idea. Oh well.

MacGyver: thanks for the correction, we're all subject to the occasional brain fart, glad to see the edumacated among us aren't exempt.

Increasing the current makes your amps are going to run hot.

 

Don't sweat it MacGyver, I promise to (unwittingly) make a real mistake soon.

A friend of mine just bought a Profile, I think it a 100W x 2 , (bright blue, don't know model #).

 

Thanks. he can live with lower output, I was concerned that there may be a serious reliability issue going on.
