What do u guys think of farad cap brands, i remember sum1 saying that it shouldnt matter much, i found a 1 farad cap a walmart for $73.56 and was wondering if i should spend the $150 on the rockford .5 cap, or buy the $130 1.2farad power acoustics one or if the $73.56 one at walmart was fine, i mean technically its just a capacitor, that has a voltage guage on it, so... its not producing sound, only providing power to help the amplifier produce the sound right? and as long as it doesnt mess up it should be good? or no. Thoughts please.
