Question about DHD NTX-2009 Car Audio Amplifier
How do i allow my dhd ntx2009 to play @ 2 ohm? do i alter the wiring to the speakers or do i alter the wiring leading from the amp into the speakers? or am i totally incorrect in the above,SO WHAT DO I DO? WHO COULD HELP?
Hi, To get 2 ohms you don't have to do anything with the amp. Simply use 2 ohms speakers for each of your output. From your other post, I gather that you have bridged it to 2 X 500 (from the default 4 X 250). If say your RMS Power at 4 Ohms is about 320 W x 4, just using 2 ohms speaker would give you roughly 600 W x 4 RMS, imagine what you get with X 2 (bridge) setting if your speaker are rated @ 2 ohms. Also from your other post, you are using "12 inch pioneer svc 800watt subs", how many ohms? So it will be the speakers determining the ohms. If your Pioneers are rated 4 ohms/800 watts, then you would need four, 2 wired in parallel as explained by Buffalo12980. Good luck. PS But of course, the amp will run hotter and auto protect may kick in more often.

What is the output impedance of the unit - factory specs? use calculations for resistances in series or parallel to get what you want. for example if the amps output is 8 ohms and you have two 4 ohm speakers wire the speakers in series. if your output is 4 ohms and you have two 8 ohm speakers, wire them in parallel to get 4 ohms. another way is if you have one 8 ohm speaker and you want it across the 4 ohm output, find a wirewound resistor that'll take the wattage rated at 8 ohms and put it in parallel so the output sees a 4 ohm load.
