greg662 Posted December 28, 2011 Report Share Posted December 28, 2011 I have been out of car audio for lil over two years but plan on starting another build here soon.My first purchase is going to be my sub 2mrow and i am wanting to run it at 1 ohm.After being on the site again for a couple of days i have been reading on ohm rise due to the box and this and that.so my question is should i buy a dual 2 ohm and wire it down to 1ohm and hope for no rise or should i buy a dual 1 ohm wire it to .5 and expect rise? if more info is needed about the system just let me know.

Noobtastic14 Posted December 28, 2011 Report Share Posted December 28, 2011 I am a believer of "Impedance Shift" not Impedance Rise. Now, how you wire it more depends on the amp you are running and the electrical you have to back it. For example, at one point in the jeep we had it wired to approx. .35ohm but with x6 rise it was closer to 2ohm once the coils warmed up. The amps didn't have any problem as long as we warmed up the woofers for a song or two before really hitting it. Some amps will kick on and instantly go into shot circuit protect from your wiring. So yeah, depends on amp, charging system and how much rise you are going to get. -Drew Quote I am a United States Military Arts and Crafts Professional.

Noobtastic14 Posted December 28, 2011 Report Share Posted December 28, 2011 this is another one of those threads where, if you have to ask about it, dont do it. Agree'd Its also one of those things that needs a, "go out and do it, and tell us how it went" response. Every car and every setup is different so there really is no straight response. -Drew Quote I am a United States Military Arts and Crafts Professional.

ALPINE408 Posted December 28, 2011 Report Share Posted December 28, 2011 well it will be on a AQ3500 with a dc power 270 alt and two xs power D3100 get the dual 2 wire it to 1 ohm and be happy and you wont have to worry about shit blowing on you Quote Have you ever had your woofers blown?

audiofanaticz Posted December 28, 2011 Report Share Posted December 28, 2011 If you want more power after rise, buy a bigger amp.. Quote Link to comment Share on other sites More sharing options...
ALPINE408 Posted December 28, 2011 Report Share Posted December 28, 2011 If you want more power after rise, buy a bigger amp.. YUP YUP!!!! this is what i do and why you will see crazy shit like 7k's and 12k's on a pair of mayhems or dc xl's i dont have to worry about ohm rise i got more power than i will every need on tap Quote Have you ever had your woofers blown?
