strapped amps

I would bet you are sitting at 2 ohm strapped. I don't see them holding up that long at .5 strapped.

That doesn't sound right at all. .25 ohms is really low for daily, unless your imp rise is like 4x. Have you clamped to see output power and imp rise?

havent officially clamped yet but on burps my voltage can dip down to low 10's

Have you tossed a DMM on the sub wires to see where you are sitting at for a nominal load?

well im not extremely familiar with how amps react when strapped together but i am posotive that my subs are dual 2 ohm/each sub is wired

in parallel to 1 ohm/and the two subs together are wired in parallel to .5 ohm final load

no but all my wires going from the subs to the amps are 4g so it shouldnt increase too much from subs to amps

Well the reason we are asking and I would say perhaps taking a look even pulling a sub out to check it over is because .25 per amp is very very low and if you dip into the 10s on a burp you would have a very good chance at killing the amps during daily play. We are not saying it's not possible, but something just seems off a bit.

well it just seems like they should be louder at .25 each. when i had one m3a on both subs at .5, my voltage dropped to 12.2.

if i have two m3a at .25 on the same setup then it should be dropping to like 8.7 volts or something. it doesnt add up. the wiring says .5,

but the performance says 2 ohm

If you are truly at .5 ohm you are limited in power by your electrical not the amps possible power. Adding amps/power is not always the answer in order to get more out of the setup. If you drop much further in voltage then you are you will end up with some pricey fog machines.

if i am indeed at .5 strapped then what would you say is a safe working

voltage to try and stay in?

You need to rewire the subs in series/parallel for a final load of 2 ohms (1 ohm each amp). Use a DMM to see what the nominal load is to check your work

above 12v is always good to shoot for

A good rule of thumb I like to follow (for daily) is not to drop below battery's (ies) natural resting voltage.

Which depending on what you have is normally between 11.8-12.5 in most cases.

ok then, ill stay above 12.65 until my other alternators get here. that way i wont have to take the subs out of the

box when i do a spl contest. i can fit two big alts on my truck and maybe three with some mods to the inner fender.

these amps should last this way for a few years if i can keep the voltage above say 13. btw does anyone know about

how many amps these draw at .25 ohm
