Can I run this amp with this sub, how do ohms work, help/recommendations...
I have a Bazooka EL150.1A amp that it says puts out 100 watts at 4 ohms and 150 watts rms at 2 ohms.
Max Power: 250W
Output Power: 4 Ohm 100W x 1 @14.4
VDC: 2 Ohm 150W x 1 Frequency Response +-1dB: 20Hz - 400Hz S/N Ratio (A-weight): >90dB THD with 22k filter: 15Percent
Low Input Level: 200mV-4V
Protection (Short, Thermal, Overload): Yes
Variable Hi-Low Pass: 40Hz-400Hz
Crossover Frequency: 85Hz Crossover Slope: 12dB/Oct
How does that work? I don't see anything on the amp that would switch it between ohms...
Does that have to do with how you wire your sub? Can someone please explain to me how you would wire your sub for 2 ohm, 4 ohm and 8 ohm.
I have an Audiobahn dual voice coil 500 watt sub. It was wired like this.
left voice coil positive - amp
right voice coil negative - amp
left and right voice coil, negative and positive were jumped together.
I do not know the ohms of the sub, I looked couldn't find it on the sub and don't have a multimeter. It looks like this:
I'm assuming it runs at 4 ohms.
What did that jumper do? Bring it down to 2 ohms?
Well when i got this sub it was used so naturally i wanted to try it out. It was wired the way said above and i hooked it up to my Bazooka amp, of which I know it is a mono amp and puts out 250 watts max at 2 ohms.
I turned it on. OOhh sounded good. I turned it up a little louder. It started to crackle. So I turned it down. And then no sound what so ever.
What the heck...
So i hooked my amp back up to my boston acoustics sub that was in the car (200 watt sub) sounds great, so its not the amp.
I took apart the box and sub and found the wiring like above.
I took off the jumper and found out i think one of the voice coils is shot. Cause if i plug it into my stereo in my room (8 ohms) on one side it works, on one side it doesn't.
What caused that voice coil to burn out?
I cranked it up on the 8 ohms 500watt system in my room (hooked it up like a normal speaker) and it works fine...
Will this other voice coil blow if i hook it back up to my bazooka? What do I need to properly run this sub. If a bigger amp is in order no problem.
Can somebody give me rules of thumb for this stuff?
I didn't find this info. in the stickies.. so if i get helpful results that may help others, could we sticky this?
