My amp is rated @ 1ohm but if i wire a 0.5ohm(to try to get more output)to it after impendence rise would it be ok? BTW its a Planet Audio BB1250.1 amp
it is common in comps to wire amps WAY below the loads they are rated to be 'stable' at.
alot of times if you just burp amps, they will shut off (unpause the track w/ the volume already up)...sometimes if you start w/ the volume low and roll it up higher to the level you want to burp at, the amp will stay on and give you a full burp. (this allows the reactive load to take over)
i have see amps wired so low what something as simple as having 2 people in the vehicle at the time of the burp would shut them off....that little amount of volume change in the vehicle was enough to keep the impedance rise too low for the amp to burp
*disclaimer* please...dont wire your amp below its rated 'stable' load unless you really know what you are doing...that is a sure fire way to kill an amp!
what i usually do is overpower the subs by alot. for example a 300 watt sub with a 2 ohm resistance, the sub runs like at 2.2-2.5 ohms when u test it on a ohm meter. so i get an amp that puts out like 2 times the rms of that sub. then test the output voltage (and square it) on the amp going to the subwoofer and divide it by the actual resistance (like 2.2-2.5). this will give u actual power wattage ratings and i would try to keep that number as close to the rms rating of the subwoofer. be sure to test it using your cars resonant freq, this way u know ur getting the most power at the given frequency
