help me understand.

Chyea! so i wanna look into a nice audio set up for my car but im not 100% sure on what exactly to look for or how it all works really. So im looking to see if anyone can explain or direct me to a website or something that can explain how car audio works. preferably starting from the basics.

Something for example would be this:

T2-250.1:

Continuous Power @ 14.4 V:

175W x 1 @ 4 ohms

250W x 1 @ 2 ohms

what does it mean when it says 175w x 1 @ 4 ohms? (Are ohms not resistance and why is there more on something with less watts?)

thanks for any help.

It depends on which sub you'll be running. Simply put with less resistance, the amp will put out more power. Hence the rating at 2 ohms and at 4 ohms.

so the 4 ohms with the 175w just means that theres less power? and the 250w at 2 ohms means theres more power? is it even nessacery to measure your system by ohms, or should you just go by the watts?

or

is there subs/amps or whatever that come like 100w @ 2 ohms and then a different one that can be 100w @ 4 ohms?

ohms are very necessary because some subs run at 1ohm, some at 2ohms, some at 3ohms..so depending on how many subs you get and what ohms you have to get a amp that will play at those ohms...for example lets say you have 2 subwoofers that are dual 4ohms..meaning you can wire them eiter down to eiter 1 ohm or 4 ohm...so you have to find a amp that will power your subs correctly on eiter 1 ohm or 4ohm's

So can i run a 500watt sub with a 1000watt amp?

yes the amount of watts the amp puts out and the amount the sub can take have nothing to do with compability its the ohms..once you find a sub and amp that will run fine together then you have to set the settings accordingly so you dont blow your subs..because if a sub is 500 watts rms and the amp puts out 1000 watts there a good chance you will blow it..

ok so as long as the 500watt sub is lets say 4 ohms and the amp is 4 ohms then i will be fine and it wont blow the sub? (man i feel so newbish lol)

ya lets says the sub you have is 500 watts and its a 4 ohm sub and the amp you have is a 1000 watt amp that puts that power out at 4ohms you can wire them together BUT you need to adjust your gains so that amp does not blow your sub OR you can get another sub thats dual 4 ohm wire them together and you get a 4 ohm load and then you can use that amp to put on those subs and run 500 to each

Alright, i think I'm starting to follow, reading that website at the moment too.

So what do you mean by adjusting my gains? does that mean setting the 1000 watt amp so that it only puts out 500watts?

and by dual subs you mean 2 subs that are both 500watts?
