Question about Phase Linear UPA424CS Car Audio Amplifier
I bought this for Subs and thought I read bridgable on the outside but no mention of bridgable on outside or in. 12 kenwood 10" older subs. All4 channels of amp available.
Can I bridge 1&2 for 1 sub and 3&4 for the other? Will it damage the amp.
Each channel has either the "+" or "-"in a circle. Are these indicaators of bridging campatable?
Thanks from a rookie!

1) If you bridge on a non bridged amp your sound will be horrible as they sine waves comming out of the two teminals will be different... I suggest removing the bridge. 2) The gain knob is to adjust when the amp will reach its max volume with respect to the sterio;s volume. 3) the LP filter is a Low Pass filter and its purpose is to eliminate the higher frequencies that do not sound all the well when played over subwoofers.

SOURCE: is it not bridgable
This amp isn't bridgeable. It's a mono amp (only one channel). You need two independent channels to bridge. Some mono amps are bridgeable if you have two identical amps but I don't think Kenwood recommends that with this amp.
