    I just picked up a great used Crest Audio LA 910 amp at a garage sale. The owner said it was bridgeable, and there is a switch for bridged mode. It puts out 325 watts/channel with 4 ohms per the sticker on the back.

    I have an SVS CS+ and would like to maximize it. Was thinking I could bridge the Crest to get the most power. Does anybody know if the Crest can handle that load with the 4 ohm SVS driver??

    Thanks,
    Troy

    Troy.

    When you bridge a power amp you get a significant increase in power output. The trade-off is that the amp will not handle low impedance loads as well. If your crest amp is rated for 4 ohms(minimum) in the stereo mode then in the bridged mode 8 ohms would be the the lowest impedance it will safely handle.

    If it is rated for 2 ohms minimum in stereo then it can drive 4 ohm loads in the bridged mode.

    All SVS drivers are 4 ohm.

    Hope this helps.

    If you can bridge it i would, as a rule especially in sound reinforcement type situations I have found that you should have about 1.5 times the rms power your sub can handle and about 2 times what the highs can handle being output by your amps. Lots of headroom keeps things clear and undistorted, distortion blows speakers way before overpowering them does-trust me ive blown enough pairs to know.
