TRTC360 Posted February 25, 2014 Report Share Posted February 25, 2014 shit I wired my 3.5k at .5 on bone stock electrical and played it like that for a little. My hifonics highs amp protected from low voltage before my dc ever did.

Wicks Posted February 25, 2014 Report Share Posted February 25, 2014 All manufacturers will include a specified input voltage range in their user manuals. Review the manuals of all your equipment. Note the highest MINIMUM value of all the equipment and don't go below that while using an analog voltage meter. If you use a digital display voltage meter then its most likely an averaged value and therefore you'll want to increase your allowable lowest voltage since the averaged reading will miss some peak drops.

Nikitaaa Posted February 25, 2014 Report Share Posted February 25, 2014 Snow posted a topic like this a while ago and got nothing but "low voltz is bad and smoke amps" or "it causes clipping yo," Until someone proves that staying on the low side of the amplifiers working voltage is harmful to the amp, I won't be scared of dipping into 11s. Even high tens. There is a low voltage protection on amps for a reason. If 11s or 10s hurt the amps you would think most manufacturers would raise the protection voltage higher than 8 or 9 colts. Again, if someone can disprove this with factual evidence, im all ears:) 2007 M/T Honda Civic Coupe EX (4) Sundown Audio X-8's (2) Ampere Audio 3800.1's (3) Stinger SPV-44 Batteries (1) Mechman 240 3:1 Ratio 4th order sealed from the trunkTEAM NWSPLBest termlab scores to date in Honda trunk:151.7db legal (official) IASCA trunk 3 classBest termlab scores to date in my walled Subie:152.9db legal (unofficial) IASCA advanced 2 class155db outlaw Link to comment Share on other sites More sharing options...
Wicks Posted February 25, 2014 Report Share Posted February 25, 2014 A manufacturer will give a specified range to operate their device in. As long as you stay in that range, then the product should work as advertised for its specific design life. Keep in mind, as I mentioned above, some voltage meters may not pick up peak drops so the amp could be subjected to lower voltages then the user realizes. Most modern amplifiers will have regulated power supplies which means that if the voltage drops, the input current will rise to allow the amplifier's power supply to stay constant. With increased current comes increased heat (P=I^2*R). Heat loss would increase with the square of the current. Increased heat inside of an amplifier will take an effect on the aging of its internal components, specifically the electrolytic capacitors. Therefore in general, its best to keep the amp as cool as possible. Of course, if an amplifier is rated down to 10V, it wont blow if you run it at 9.9V. The manufacturer will have some design margin in the product for reliability. But the further you push the limits, the faster the device will wear out and fail.
