im new to the whole car audio thing.....and i was just wondering, should my amp and sub have the same OHMS?

Answer 1

Yes, keep the ohms the same as well as match the RMS watts of sub and amp.

For instance if you have two subs and they are 200 watts RMS @ 4 ohms each, then you would need an amp that is 200 watts RMS X 2 @ 4 ohms. Wire each sub to each channel on the amp.

OR

Get an amp that is 400 watts RMS X 1 @ 2 ohms and wire the subs in parallel. Like this:

Answer 2

hel#ya they should have the same OHMS if the OHMS of the sub is lower than the amp can be stable at it will fry your amp.ex if you had a mono amp that is 2ohms table and you have 2 subs that are 4ohm each you will have a 2ohm load to the amp and that is fine for that amp.most 2 channal amps are 2ohm in stereo and 4ohm in mono (bridged).make sure your amp can have the load of ohms you are looking for.

Answer 3

it doesn't really matter. it all depends on the brand. don't all ways go with the same brand. Some brands have good amps and bad subs and other brands have good subs but bad amps

Answer 4

impedance is something that the amp has to adapt to... the speaker has a guarenteed impedance the amp will only be ably to adapt if it is of good quality... JL Alpine etc are made well.. and they are capable to do this but the cheaper the amp the more likely it will burn up. so if you buy junk amps .. matching the impedance will hardly prolong the life of the amp... and the speaker for that matter. good quality products will provide good quality sound for a long time.

Answer 5

yes.. try to keep it all the same...
