RainStryke Posted November 3, 2014 Report Share Posted November 3, 2014 Well... it's going to be different for some people. It's not a one voltage fit's all... If you have a 12v system, you won't want to see it go below 12v... That's when your car is struggling to get the power it needs to operate properly... So that would be the danger zone, anything below the voltage it's built for. Link to comment Share on other sites More sharing options...
alaskanzx5 Posted November 3, 2014 Report Share Posted November 3, 2014 Most reputable brands are good down to 9v and up to 16v. However if your amp is rated to do 500rms at 1ohm voltage at 13.5 then anything below that you wont come close to rated power. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

Syphlyn Posted November 3, 2014 Author Report Share Posted November 3, 2014 Most reputable brands are good down to 9v and up to 16v. However if your amp is rated to do 500rms at 1ohm voltage at 13.5 then anything below that you wont come close to rated power. I always hear people say voltage drop will fry your amp...so if I'm dropping to 12 or so could that wreck anything? I'm wired to 1 ohm on a saz 2000d.

alaskanzx5 Posted November 3, 2014 Report Share Posted November 3, 2014 It depends on the install and amp. If that amp is rated for say 11v to 16v and you drop below 11 or close to you get into a higher risk area. Or if you mount it in an area where airflow is low you can overheat it specially if running low voltage (more stress higher heat). t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

Wicks Posted November 3, 2014 Report Share Posted November 3, 2014 In the manual for the SAZ-2000d, it states: Operating Voltage 10-18V. So you can safely operate it at 10V. But I would use an analog voltage meter that doesn't average if you're going to risk going that low. I would assume this has a regulated power supply. Keep in mind that a regulated power supply will want to output consistent power so at lower voltages it will draw more current which is even harder on your electrical which can in-turn cause your voltage to drop further.

Nikitaaa Posted November 3, 2014 Report Share Posted November 3, 2014 Agreed with most of the other posts here. Anything under 11 is unsettling and that's when I'll back down.
