I have 4 speakers one pair of speakers are 150w and the other pair of speakers are 120w could someone tell me what speakers are louder because I don't know ?? my amp is 100w?
There are too many factors and variables to consider when it comes to speakers. Yet, the general rule is the lower wattage speakers will be louder than the higher wattage speakers because they require less power to drive them. Then the other things to consider is the actual construction of the speaker and if they are mounted just on a surface in a car or whether they are mounted in an enclosure. Then I don't have enough information about the amp. Is it set up as a four channel amp, or are you going to run the speakers in series or parallel front to back? Personally I would add a second amp so there is an amp for each pair of speakers. You can purchase all sorts of extras at car audio stores such as faders between the two amps, or a crossover device with performance controls such as bass, midrange, and treble. Yet, if you are determined to stick with what you have, and your amp is only two channel, then run your speakers in parallel going first to the high watt speakers.
