[QUOTE="adulbrich, post: 8360387, member: 661255"] What kind of amplifier do you run and why? [B]Please contribute to the poll![/B] I am going to use the statistics in my English paper. Why did you chose Korean or Brazilian? I've run both, but only have my experiences and opinions. Main reason I'm not running half bridge anymore is I can't afford to upgrade to the next level. Big gap in price/power for next Brazilian amp up. I plan to wire my M4a lower in the future when my electrical is better & I need/want more power (will get new subs or re-cone). For those who don't know Most amps people run are Korean. Korean amps are half-bridge and only use half the rail voltage inside the amp. They are less efficient than Brazilian amps, but are "more reliable". They can be wired lower than "equivalent" Brazilian (full bridge) amplifiers. Half bridge components are commonly over-built. When you wire lower, your amp sees less impedance. More current is allowed to flow. Beefy Korean amps have strong enough internal parts to handle the extra current flow. Brazilians are not "over-built" and cannot handle excessive current. They make their power by putting out a higher voltage, because they use the full rail voltage to drive the load. Also, they are more sensitive to voltage fluctuations. They don't like low or high voltage. The argument is that full bridge will never do rated power because of impedance rise.
