Totalnoob Posted January 7, 2015 Report Share Posted January 7, 2015 OK in general how much more watts could I run if I run more power at a higher ohm load with the same electrical due to the amp being more efficient. For example if I am currently running 2k watts at 1 ohm without dropping below 13v with my electrical...what kind of power could I possibly run at 2 ohms. Like could I get another 2k amp and strap them to 2ohms for 4k of power and run it ok (not dropping below 12v) Or maybe just run a 2k amp at 2ohms to one voicecoil and the other amp to the other voicecoil at 2 ohms so each input sees 2ohms because the sub is dual 2ohms. To get a little less current draw more like 3000watts So basically how much more watts can I run going from 1ohm to 2ohms with the same electrical without dropping below 12v. I know it is probably impossible to tell but I am hoping some has experienced this on here to just get an idea. Link to comment Share on other sites More sharing options...

It depends on the amp, but usually it's not that big of a difference, around 10% difference if not less. Thinking is the root of all problems... You ALWAYS get what you pay for.

Miguels Posted January 7, 2015 Report Share Posted January 7, 2015 Strapping amps at 2 ohms don't work that way. You would strap at 4 ohms so each amps sees a 2 ohm load. my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
Aj11 Posted January 7, 2015 Report Share Posted January 7, 2015 you won't see a big difference..now going from .5ohm to 2ohm, or 1ohm to 4ohm would be a big difference. most good amps have a 97% efficiency rating or more at 4ohms jvc deck stinger 1800 front hc 2000 kinetic rear 2 runs of 1/0g big 3/4 ct 60.4 2 ct 1400.1 ct EXO 15 d1 lots of deadner type r comps front stage 6 kicker tweets rear stage lots of great stuff coming soon ho alt more bats ct comps for front stage more deadner sweet amp rack lots of L.E.D lights new deck (thinking 80 prs, or flip out) Link to comment Share on other sites More sharing options...
Miguels Posted January 7, 2015 Report Share Posted January 7, 2015 I agree. The efficiency is not far off maybe 5% difference.

Aj11 Posted January 7, 2015 Report Share Posted January 7, 2015 if I'm not mistaken a 1500w amp at .5ohm draws almost the same current as a 3000w amp at 1ohm. even tho the watts are way different. if that comparison helps at all jvc deck stinger 1800 front hc 2000 kinetic rear 2 runs of 1/0g big 3/4 ct 60.4 2 ct 1400.1 ct EXO 15 d1 lots of deadner type r comps front stage 6 kicker tweets rear stage lots of great stuff coming soon ho alt more bats ct comps for front stage more deadner sweet amp rack lots of L.E.D lights new deck (thinking 80 prs, or flip out) Link to comment Share on other sites More sharing options...
kirill007 Posted January 7, 2015 Report Share Posted January 7, 2015 you won't see a big difference..now going from .5ohm to 2ohm, or 1ohm to 4ohm would be a big difference. most good amps have a 97% efficiency rating or more at 4ohms Please don't post this misinformation.

That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
