    rules for bridging speakers

    i have a 2 channel amp for my 6x9s and 6.5s. how do i bridge them. if one speaker each speaker is 30 rms do i set each channel to 60 rms if its on the same channel or set it to 30?

    You can't bridge speakers.

    You can connect them in series or in parallel.

    If you connect two 4 ohm speakers in series, then each speaker will get half of whatever power your amp deliverers into an 8 ohm load.

    If you connect two 4 ohm speakers in parallel, then each speaker will get half of whatever power your amp deliverers into a 2 ohm load.

    For example, if your amp delivers 50 W RMS into 8 ohms and 140 W into 2 ohms, then with a series connection each speaker will get 25 Watts and with a parallel connection each will get 70 Watts.

    A parallel connection is the preferred way to connect multiple speakers if they are not identical to aviod the impedance of one affecting the other and vice versa. Impedance is not constant and varies with frequency - the impedance of a 4 ohm speaker at resonance can be as high as 60 ohms.

    the amp is pretty crappy and doesnt say much about it anywhere so all i kno is that it has high pass/ lowpass and is 200 watts per channel. 2 channels, stable at 2 ohms.

    Assuming it's 200 Watts into 2 ohms, you'll blow your speakers. They will each see 100 Watts. What brand is it?
