My subwoofer amp, a Profile BAJA 100 a CC special, at one time powered one rear deck mounted TC sounds 6.5 inch midbass driver playing the role of free air subwoofer. The amp at 75 watts per two channels and 150 watts bridged proved good enough for powering that driver setup
Over the weekend I took a 6X9 speaker box and placed two 6.5 inch Audiobahn AMD60 onto drilled sides of the box and then mounted the box below the rear deck opening. These free air mounted driver each have a 3ohm rating. I wired each plus and minus terminal directly to the amp. Did I just described a parallel circuit or a series circuit. Parallel I think. When I began to play the stereo again I was really happy with the additional 3dbs of sound. Yes I still could bottom both drivers but the added bass was a plus. Then it happened. While playing some bass heavy music the bass output simply dropped. What had happened. It seems that the heat sensing circuit breaker tripped for all I had to do was turn off the stereo for a while letting the amp cool and the sub amp came back on. So I pose this question. Should I wire the speakers in series so that the amp sees 6 ohms or should I get a fan to mount on the amps heat sinks to circulate the heat better when the amp sees 3 ohms from drivers wired in parallel.
Lastly what is the cheapest 1 ohm stable amp on the market for I ask this question because I plan to add two additional drivers in the future mounted in another 6X9 inch box mounted on the other side of the rear deck in free air form.
I also was consider whether buying a JBL b300.1 amp would fix my problem but I have not decided yet.
If I wired the speakers in series I will resolve resistance issue but will I not also at the same time lower the spl output of the two driver combination?
All comments are welcome.
