comatosetaco Posted May 7, 2009 Report Share Posted May 7, 2009 I was wondering if anyone could tell me if either of these Memphis amps could be run at a half ohm on a daily basis. I have one memphis mcd1500 and one st1500d I just need to know if I can run either of them at a half ohm! Please let me know! Quote Link to comment Share on other sites More sharing options...
comatosetaco Posted May 10, 2009 Author Report Share Posted May 10, 2009 bump! Can anyone shed some light on this for me please? Quote Link to comment Share on other sites More sharing options...
raytard Posted May 10, 2009 Report Share Posted May 10, 2009 i personally wouldnt run anything at a half ohm daily, but thats just me (effeciency drop, extra heat, and current draw are not worth the extra couple of watts you get) Quote Build: http://www.stevemeadedesigns.com/board/ind...hl=avalon+build monster/rockford/kicker/stinger cables, pioneer source, jbl highs/amps, kinetik/shuriken batts, iraggi alt, dei security, dc subs(atleast for now) Team DC Link to comment Share on other sites More sharing options...
comatosetaco Posted May 10, 2009 Author Report Share Posted May 10, 2009 that is a good point im just too lazy to swap the wiring after every competition! Quote Link to comment Share on other sites More sharing options...
raytard Posted May 10, 2009 Report Share Posted May 10, 2009 maybe do a bolt terminal system where all you have to do is unscrew 2 nuts and swap a wire Quote Build: http://www.stevemeadedesigns.com/board/ind...hl=avalon+build monster/rockford/kicker/stinger cables, pioneer source, jbl highs/amps, kinetik/shuriken batts, iraggi alt, dei security, dc subs(atleast for now) Team DC Link to comment Share on other sites More sharing options...
CodyB Posted May 10, 2009 Report Share Posted May 10, 2009 (edited) Why not run both amps, or sell/trade one to match two of them and run em both?

Loudcav Posted May 10, 2009 Report Share Posted May 10, 2009 rumor is they will protect at 1ohm Quote Link to comment Share on other sites More sharing options...
comatosetaco Posted May 10, 2009 Author Report Share Posted May 10, 2009 Here is the situation I have to a t. Right now my box im running has two different sets of ports one for daily use tuned to peek at about 39 hz and one set for comps tuned at 45hz which needs to come up to around 50hz for the best performance. The box is right at 9 cubes and is built for 3 memphis m3 12"s with dual 4 ohm coils and has five four inch aeros that fire out the top of the box. The box works great and never tops out so I know I can feed it lots more power without a problem. My current problem with the system is that my amp is wired at 2.66 ohms so at best im probably only making 1100 to 1200 watts. With the class i normally compete in in USACi i can run up to 1800 watts at 4 ohms right now im at 750. I would like to have close to 1800 watts at 4 ohms and be semi stable at a .5 ohms load for comps that could be good for almost 5000 watt increase. Right now sealed up mic on dash fully legal with the 39hz ports in it will do 145dB all day long and 147.5 on the pass floor board usaci outlaw style. With the comp ports tuned to peak at 45 hz it will do 149.5 in the pass kick and never metered it legal. So if you would give me some ideas here I know it can do a lot more just need some suggestions. Quote Link to comment Share on other sites More sharing options...
