lc 3 headunit convertor to rca

hello? what info do you need to answer my question?   thanks

Does it have any info such as XXX watts per channel into X Ohms?

I wish it said something like that I should probably find a manual or something but BOTH my crossfire and my jensen amp put it in wording like that

just says 2-channel bridgeable and dont run mono bridged mode in 2ohms speaker wiring (I assume) configurations

I think its: "75x2 rms at 2 ohms stereo, and 150x1 at 4 ohms bridged. What is the LXA300 RMS output...2 x 75 watts RMS per channel (2 x 100 watts peak) 150 watts RMS bridged into a 4 ohm load" If both of my subs say 275w, this is per channel right? So I can add way more watts? Added watts:     2 speakers x 200/each?   RMS         or      2 speakers x 100/each?         or      1 speaker x 50each? In fact, isnt it a little worse to be under powered than to be overpowered. I'm told you should get an amp that is nearly double the power of the speaker?
