    So say I have a sub that is 150w rms and 300w peak and is a single 4ohm and I have an amp that is 150wx2@2ohms and 300wx1@4ohms, will I be fine bridging the sub to 300w? Someone is telling me that it will be fine. I was always told to only go by the rms and not the peak, is this not true?

    You can't bridge a single 4 ohm sub. If you mean't then amp by mistake then you will over power the sub. What is the sub + amp make and model?

    Yes, bridging the amp will give you 300RMS and as long as you set things right you wont blow up the sub.

    You can simply set your gains so that you never give the sub too much power. Also, if you know what you're doing and the sub is in the right enclosure you can give it more than rated power and be fine. There is a reason why my 6.5" subs see double their RMS power and live to tell the tale. :D

    Yeah I ran a sealed 12W7 off of 1000/1 then switched to a slot ported and should run about 500/1 but I am still running 1000/1 to it. Just turned the gain down.

    sorry about that I mean the amp.

    the amp is a Cadence TXA 150.2 (using this for testing)
    and the sub is a Kicker CVT 6.5"

    What I am planing to do is put it under the passenger seat, since it's about 2.something" mounting depth, that gives me somewhat of a better chance of response.
    Although they have a 2 ohm and a 4 ohm, the person that is trying to sell me one of these subs only has the 4 ohm one. They are 150w rms and since I doubt I will be putting it in the right enclosure, I don't want to over power it.
    I usually set the gain to 12 o'clock on all my amps, I don't like to risk blowing out a sub.
