Johan Gustavsson Posted January 29, 2013 Report Share Posted January 29, 2013 Hello! I have plans for purchasing two LVL 3 15" and a DC 3.5K amp, should i go for subs with dual 2 ohm coils or dual 4 ohm coils? With dual 4 ohm i get to run the amp in 1 ohm and with dual 2 ohm it get's down to 0.5 in the theory. Is 0.5 the way to go because of the impraise? I will mostly play music but i wan't to be able to go loud also. The car is a BMW E39 540i/6 Touring. Any thoughts? Quote BMW E39 540i/6 Touring Bassrace competition car with Impact and DC Audio.

08tahoe Posted January 29, 2013 Report Share Posted January 29, 2013 (edited) get two D1 subs and you can wire them to 1ohm. edit: ok i just checked dc's website because I didn't know if they made d4 lvl 3 subs, but they do so yes you can get two d4's and wire to 1ohm. You can also wire at 1 ohm with two d1's. And NO don't wire at .5 Edited January 29, 2013 by youngsticky Quote Link to comment Share on other sites More sharing options...
Johan Gustavsson Posted January 29, 2013 Author Report Share Posted January 29, 2013 OK, any reason not to wire at .5? Will the power be enough from a 3.5k for two lvl3 15 wired at 1 ohm?

Azagtoth502 Posted January 29, 2013 Report Share Posted January 29, 2013 Lower impedance builds more heat, dirtier signal, taxes the electrical more. But kids today want them LOUDS so.......

bdog Posted January 29, 2013 Report Share Posted January 29, 2013 only wire at .5 ohm if your willing to blow your amp..not saying your going to but it might happen Quote REP Link to comment Share on other sites More sharing options...
08tahoe Posted January 29, 2013 Report Share Posted January 29, 2013 You will also void your warranty on your amp if you wire at .5 Quote Link to comment Share on other sites More sharing options...
Johan Gustavsson Posted January 29, 2013 Author Report Share Posted January 29, 2013 (edited) I know what it takes to run an amp at .5, but i don't have any experience loading DC amps at .5 so i wanted to hear your thoughts. So will the 3.5K amp and 2 x lvl3 15" d4s be good or do i need to get an 5.0K?

srool Posted January 29, 2013 Report Share Posted January 29, 2013 The 3.5K is capble powering 4 lvl 3's. they're 900RMS each. I'd say go with more powerful subwoofers and not more powerful amp. Quote Link to comment Share on other sites More sharing options...
CJ18 Posted January 29, 2013 Report Share Posted January 29, 2013 If you are wanting to power 2 Level 3s with the 3.5k, I would go with Dual 1 ohm subs and wire to 1 ohm.(I would also add the Level 4 upgrade to the Level 3 subs). If you wanted to drop down to .5 ohm(this will void your warranty and requires a stronger electrical system to properly supply the amp), then I would run a pair of Level 4s.

corey0928 Posted January 29, 2013 Report Share Posted January 29, 2013 Idk why anyone is saying powering 2 level 3s with a 3.5k is a good idea. First of all of he's not sure about dual 2 or dual 4 should he really be going double the rms rating with the amp? Why not a dc 2k for the pair Quote Link to comment Share on other sites More sharing options...
