Rick, sorry to take so long to reply. Been chasing around doing Christmas. I just went and checked. I have a Patriot and a Ragin' Cajun in there. I figured why get two of the same speakers. Let them each do their thang.

So far, works great. I can tell the amp is a little heavier though. Haven't tried to see how loud it will get, although I think these are more sensitive speakers and should be more efficient than the stock Jensen's.

Just to close this ancient argument, Prolux is more correct. But we are also measuring two different things. Perceived volume and wattage are not the same thing.

Multiplying amps does not add their wattages as decibels. Sound pressure is not linearly additive. If you add 20 pounds to 20 pounds, you have 40 pounds. If you add 20 decibels to 20 decibels, you do NOT have 40 decibels. This is why traffic noise doesn't add together and kill you. If you combine two 100 db sound sources (two loud amps), you get 103.01 db, or about one-third of a perceived doubling of volume. Not 200 db. If volume were additive, the Rush concert I went to last year would have vaporized the audience.

Two 25-watt amps do not equal the audio output of one 50-watt amp.

There's a neat calculator here: http://www.sengpielaudio.com/calculator-spl.htm

you don't understand DBs each 3+ db is double as each 3db- is half
