how do i get a dual 4 ohm sub to take a dual 2 ohm load?

Question

i have a sub that has dual voice coils, and each coil has a 4 ohm load. my amp is mono, but has two channels and gives its best output at 2 ohms x 2 ( 2ohms per channel). a total of 2200 watts rms. i don't know what the max output of the amp is. but my sub can handle the 2200 watts rms. how do i get the 2ohms x 2 from the amp wired to the sub?

Answer 1

You don't.this is about impedence matching. based on a pire chart (E=IR)you should be able to fiure it out. going lower than 4 ohms would tend to put more amps into the load tending to burn that circuit so you'd have to put resitance in there somehow with a resistive load back to ground in the loop. got electronics? as u can figure u might send 4400amp somewhere where u don't want it But watts are different altogether anyway.

Answer 2

Your amp can't be mono and 2-channel both. If it's a 2-channel amp, it's probably not well matched to the sub, and there's nothing practical that you can do about it. However, if it's a mono amp that just has two sets of terminals, then it's probably designed for a 2-ohm load like you'd get if you wired your sub in parallel. What's the make and model of the amp?

Forget about wiring in resistors; it's pointless. Adding resistors in parallel will make the amplifier put out more wattage, but every bit of that extra power will be used solely to heat up the resistors. Your amp will be working harder and less efficiently, but the subwoofers won't be getting any more power than they would without the resistors in the system.

Answer 3

Maybe learn some basic electronics before you select components? Yes, there is a cure...........wire a 2 ohm resistor in each channel sub wire. In parallel. that means solder a proper size wattage 2 ohm resistor across the terminals of yer sub and connect the wires as usual. one resistor required per channel. No plug in wires...........solder everything,,,,,,,,,,Pushing that much pwr your first short will fry your amp. Insulate well. Those resistors will heat up. Make sure they have ventilation.

Answer 4

bridge your amp to one channel running the subs in series this should take your amp to 1 ohm stable
