jonathancullen89 Posted June 16, 2008 Report Share Posted June 16, 2008 alright i dont know what to do, i can either wire the sub(dual 4) down to 2 ohms and wire it to one of the channels on the amp. otherwise could i wire it to series and bridge the amp? here are the specs of the amp 4 Ohm RMS Power: 2 x 150 Watts @ 13.8 Volts 2 Ohm RMS Power: 2 x 300 Watts @ 13.8 Volts 4 Ohm Bridged RMS Power: 1 x 600 Watts @ 13.8 Volts would running it bridged with an 8 ohm sub give me the 300wrms i need for the level 2? wouldnt it be more efficient. i need somebody's advice, thanks. john 1992 cavalier build 1992 blazer s10 kenwood cd hifonics hfi2500d 6 soon to be 12 12" hifonics hfi12d4's shit ton-o-wire Blurred Vision Audio Team SMD feedback/refs. clicky!- Link to comment Share on other sites More sharing options...
ISO Posted June 16, 2008 Report Share Posted June 16, 2008 yes 8 ohm bridged would be 300 whats. 8 ohm bridged is the sum of the wattage of your 4 ohm stereo numbers.

jonathancullen89 Posted June 18, 2008 Author Report Share Posted June 18, 2008 alright got the amp and got everything installed today! big difference going from 25wrms to 300rms lol. now i have another question. when installing the amp i had to turn the gain up quite a bit in order to make the sub loud, there is no audible distorsion and i turned the gain down a little after i could start to hear it. but right now my bass boost is on about +10, gain is almost 3/4 of the way up, and bass knob is at 50%. ive never had to turn an amp up this much, is it because i am running it at 8 ohms? the subwoofer is deffenetly louder and sounds alot better after i added more power but i just dont understand why i had to turn the amp up so much. any ideas? thanks 1992 cavalier build 1992 blazer s10 kenwood cd hifonics hfi2500d 6 soon to be 12 12" hifonics hfi12d4's shit ton-o-wire Blurred Vision Audio Team SMD feedback/refs. clicky!- Link to comment Share on other sites More sharing options...
