im new to the car audio scene can someone please explain how ohms are related. like i know but not in depth, so whats the diff between 4 ohms and 2 ohm or whatever?
The low resistance you run at ( Measured in OHMS ) the more current you are drawing from you electrical system. Usually meaning more power that an amp can give to the subwoofer.
So if ur running at 4 ohms lets say ur amp is rated for 400 watts RMS, now you use the same amp with a 2 ohm load and it will be rated about 800watts RMS.
not quite... look at your amps specs. It will tell you what ur amp is rated for (rms) at different loads. Usually 4,2, and 1 ohm(if stable to 1 ohm) what amp to you have? sometimes it doubles but not always.
You dont change it like a switch. Its the load you have hooked up to the amp. If your sub is 4ohms then ur running a 4ohm load on the amp. If you get a dual voice coil 4 ohm sub you can wire the sub in parrellel and get a 2 ohm load. Or run 2 subs 4ohms each in parellel and have a 2 ohm load.
and these rating are just for guidlines. Normally subs arent exactly 4 ohms more like 3.5 or 3.75. so the ratings are just to show you the amps rating at certain points.
actually im in the process of buying a new setup, but whats the definition of continous power that just means how much power is being fed to the subs constantly right? thanks for your help I must be gettin annoying lol.
no its fine i like to help. I've gotten so much help on the forum i can share the knowlege i do know.
Its like the amount of power the woofer can handle at a constant rate without damaging it.
like a warenty issue it shouldn't break with that much power.
Its usually 50-70% of the peak power and since all the frequencys going to the subs are mostly sin waves it is the average power of the signal going to the sub.
How much are you looking to spend on a system and what are you looking for...
really loud , good quality, low bass, tight bass???
