whts the difference?

2 channel=2 power channels
4 channel=4 power channels

so a 2 channel amp will have power ratings like 50rms watts@4ohms X2 channels

and a 4 channel amp will have power ratings like 50rms watts@4ohms X4 channels

the 2 channel amp can be bridged into a single channel

the 4 channel amp can be bridged into 2 channels

also planning to change all 4 of my speakers to JBL in near future

the only difference is the amount of channels. that is the only spec that changed universally between them.

and since you have no idea about this stuff get me the model number of the sub you are wanting to run.

JBL MODEL GT-X1150

having issues finding that model since all i get is stores based in India lol.

are you in the US or what?

it appears to be http://www.onlinecarstereo.com/CarAudio/p_35628_JBL_CS1214.aspx with slightly more power handling from what i can tell.

is it single 4 ohm voice coil as well?

HIGHLIGHTS:-

SPEAKER TYPE :-12" (300MM) subwoofer

MOTOR:-HIGH-EXCURSION,HIGH-BL

NORMAL IMPEDANCE :-4 OHMS

POWER HANDLING,PEAK:-1150W

POWER HANDLING,CONTINUOUS AVERAGE:-285W

FREQUENCY RESPONSE:-23HZ-450HZ

SENSITIVITY (2.83V/M):-90DB

I m in india
I can get the specs for u lmk if tht helps

nah thats fine. all i needed to know was

POWER HANDLING,CONTINUOUS AVERAGE:-285W

NORMAL IMPEDANCE :-4 OHMS

so since you are in india i probably wont be able to find an amp for you so i'll explain how to find one for yourself.

depending on what you can find here are the things you need to look for on the amplifier:

monoblock(single channel since its a subwoofer) with 250-300 RMS watts@4ohms(nominal, continuous average are other names for it)

2 channel 250-300 RMS watts@4ohms(nominal, continuous average are other names for it) either bridged or per channel on this one.

if you have anymore questions let me know.

Ok so a 2 channel will be fine n if future if I wanna add one more speaker I can. On a 2 channel amp?
