I wanted a bit more juice out of my amp and more umf from the speakers so after reading online that it is 2 ohm stable i decided to hook my speakers up the same as you would with subs to turn them to 2 ohm parallel to get more power. so 2 subs 1 channel or in my case 2 speakers 1 channel. after pumping it nicely for 10 mins it went dead. I felt the unit and it was really hot you almost cant touch it. once cooled down it starts up again but now it makes ghosting music like as if its like a singer on the far end of a long hall way without the echoes. that was probably the cause. are speakers not ment to be hooked up parallel only subs or amp was the amp about to die and felt like it at the time. Please let me konw what i did wrong dont want to blow up another amp. thanks |

New member Username: Estima04Post Number: 10 Registered: Aug-12 | Thanks joe so when bridged it must stay at 4 ohms. I mustve done option 3 but I cannot find where it says bridged 4 ohm I have some questions and may sound ignorant please dont take it that way and with no disrepect a sound enthuisast wanting some help specs of my amp Details: option 1 50 watts RMS x 2 at 4 ohms option 2 65 watts RMS x 2 at 2 ohms option 3 130 watts RMS x 1 bridged output stereo or bridged mono output Tri-way capable (Tri-Way crossover required) requires 10-gauge power and ground leads � wiring and hardware not included with amplifier Bass Engine� features: selectable 80 Hz high-pass/low-pass crossover, 18 dB/octave tuned Bass EQ (8 dB bass boost at 50 Hz) MOSFET power supply STAR Topology (minimizes internal noise and prevents ground interference) speaker- and preamp-level inputs gold-plated screw terminals blue power LED 8-11/16"W x 2-5/16"H x 10"D 1-year warranty 1. what I was trying to achieve was the 2nd option, can you show me how that is achieved. 2. is hooking up any speakers in parallel regarded as bridged and must stay at 4 ohm and not the case with subs? 3. the saying goes a stupid question = a stupid person I hope you guys dont feel that way about me here comes the dumb question, i thought that as it can handle a 2 ohm output at 65w X 2, speakers in parallel is 2 ohm so it should be ok and another 2 in parallel in the 2nd channel but i guess thats not how you do it? Thank for your patience |
