I Recently had a DB6500 Blow out with no warning and im down to 1 speaker in my Suburban so I decided im going to purchase another set of speakers for the rear. My current gain is set to 18.36 volts using the method below I can safely go to 22.36v! The gain on the amp will only go 18.36v without going over the 22.36v needed and the next level will take it to 28.52 my question is will that be too much for the speakers or will I be ok? The speakers I plan to purchase are the MMC6500 The amp Im using is the Alpine F-545 125w RMS x 4
Using this method with a DMM
Voltage of the output = sqrt(RMS Power X impedance of the speaker)
Say the amp provides 100WRMS into a 4 ohm speaker:
Voltage = sqrt(100W X 4 ohms)
Voltage = sqrt(400W*ohms)
Voltage = 20V
Also what Crossover frequency should I put them at I had the Db's @50hz with the crossovers that came with them installed hoping that would be ok. What do you guys think?
