impedance question
ok guys , I need some help here plz.
I have 2 front JBL speaker 6.5" with 2 OHMS, hooked to SSpn520 on 2 channels.
I bought kicker today for the rear pods on tour pack, they are 6.5" with 4 Ohms.
i was thinking to bridge them to get to 2 Ohms. after splicing wire from radio plugs. i said to my self it is amplifier and it should ran 4 ohms on single channel without bridging as output. i read the manual of the amp and it shows u can use any ohm from to 2 to 8 ohm as input .
my question is should i just use the 4 ohms speaker as output without bridging the 2 speakers, or the mix isnt good for the amp? thanks .
In other world, the amp input will be 2 ohms, and the output will be 4 ohms???

lol lol lol i was damn for minute here lmao. while i was looking at the speaker print it shows 2 speakers bridged to one channel. and was thinking i have to bridge at the speaker s end . while the manual shows i can bridge to channels to 2 speakers lol
i only need to switch wire at the end of amplifier to get 2 ohms .
i think it is not a good idea to lower the impedance as far as the amp goes. manual shows bridged only at 4-8 ohms, i am getting confused here lol

thats what i end up doing. the front with 2 ohms , and the rear with 4 ohms. i adjust setting and those kicker are load but no bass at all. the same setting with jbl and the jbl has some bass . kicker are like i am listening to headset with no bass . i dont know if i like them or not , will give them till tom and check them out again may change my mind lol.
thanks for the reply.

impedance question
Two four-ohm speakers will result in a two-ohm load, regardless of what you do with your amplifier.
Bridging two channels of your amplifier will result in greater available power, but in mono, and with less impedance flexibility. Example: amplifier puts 200w into two channels at 4-ohms. Bridging those two channels will get you 400w mono available, but with an 8-ohm maximum load.
Don't bridge your amp unless you're ok with losing stereo, and your speaker impedance won't drop your load below the minimum impedance threshold.
