So I have two Alpine 10: 1042 dual voice coil 4 ohm subs that require 500W RMS. If I want to run both of them in a 4ohm setup to get the best audio clarity and hard hit (from what I've read) I will need a single channel amp that will distribute 1000W X1 at 4ohms? I've been trying to do all my research for awhile on power distribution but I just had that quick question. Thanks guys/gals!

 

well my question is dose the set need 500rms or each sub need 500 rms

but if you wire each 4 ohm sub's voice coils in parell you can wire the subs in series that would give you a 4 ohm load over all

if the set takes 500 wats RMS then a 500 watt AMP is what your going to want

some people would get a 2 channel amp and bridge it others would get a mono block amp and run it that way its kinda like 12 or a dozen its whichever you can get your bang for the buck out of

 

Each sub requires 500W RMS

 

You could get an amp that can put out 1000 watts RMS and is stable at 1 ohm (doesn't have to be that high - a good 500 WRMS amp would do). Wire your subs parallel so you present a 1 ohm load to the amp. Probably get those subs to hit pretty hard with that configuration.

Here are a couple of wiring options for you, one is for a 4 ohm load, the other for a 1 ohm load.

An amp that is 1 ohm stable is going to cost more than one that isn't...

If each sub can handle 500 watts rms, I'm assuming 250 each voice coil... Each voice coil is 4 ohms, wire 1 voice coil to another in series, (8 ohm) then wire the 2 subs up to the amp parallel (4 ohms)... If you have a 1ch mono amp...

2 channel amp? Find a 2 ohm stable one... or one that can bridge to 1 channel 4 ohm. Or a 4 channel 250watt rms amp would work too...

As noted, as ohm load decreases, distortion usually goes up...

Thank you everyone for your posts. I got the HiFonics brutus 1606D amp and will be wiring the subs to a 1ohm configuration.
