Well it finally happened. I tripped the thermal protection circuit switch again of my CC special profile Baja 75watts per channel amp playing some old 70's bass heavy funk music while it was 90 plus degrees with 70% humidity here in NYC but only this time the amp was damaged to the point where I had to replace the heavy load, two audiobahn amd6 midbass drivers rated at 3ohms wired in series used in freeair mode, with a lighter load, one tc sounds 6.5" driver mounted in a sealed box firing thru the rear deck hole because the amp made a rumbling sound a low and high volume when powering the heavier load. I thought that this rumbling sound was a blown driver but after removing the heavy load and testing it at home it was discovered that neither driver was damaged any further. So what kind of damage could my amp have gone thru where it makes a funny rumbling sound under a heavy load a sound that it does not make when under a light load.
One thing must be said though and that is I must decide quickly whether to purchase a single channel 1ohm stable amp from JBL (the Bp150.1 or Bp300.1) or go with a 1ohm stable two channel amp from Kicker, or MTX to be used in bridged mode. Within another post a discussion on what was better a 2 channel amp bridge or a one channel amp with equal power was made. Is it true that a 1 ohm stable two channel amp is not 1 ohm stable in bridged mode. If this conclusion is correct then I will go with the one channel amp. My only concern with the JBL amp is that the bass boost is only 6db and the max input voltage is 4v while the profile baja is 18db and the max input voltage 7volts (I think) The reason I must quickly decide is because I need more bass for if it is not thumping (figuratively what I feel thumping is I am not driving with a happy smile on my face down the road. For a freeair load in the trunk gives deeper lower bass than a small sealed box can and I like my bass sloppy and lose not tight unlike my preference in women which is the reverse.
