Hey i have Two 10" Infinity Kappa Subs with 350 RMS power and 1400 peak power as it is right now I have a ZX 450.2 kicker amp on them and its just not working for me it doesnt hit hard at all so im thinking of upgrading the amp to a mono channel to get more power and Im wondering if I should do two seperate monos or one high powered mono i was told with a mono amp on two subs that it will cause the two subs to play as one consistent unit and not as two separate subs. Im thinking of putting a ZX1000.1 kicker amp instead of the 450.2? what suggestions does anyone have

What voice coils are on the subs? The kicker 1000.1 is a beast so that might even be over kill on those subs

you only need a ZX750.1 to run thos subs. whats the ohms rating on thos subs? dual or single voice coils?

also you want the subs to run the same if they dont and one sub hits and the other dont your loosing bass

Option 2 (series/parallel) = 2 ohm load
Voice coils wired in series, speakers wired in parallel
Recommended Amplifier: Stable at 2 or 1 ohm mono |

whats the difference between 4 ohms 2ohms and 1 ohms to me i would think 4 ohms would be the most powerful the one the hits the hardest am i wrong?

ohms is resistence. 4ohm has more resistence then 2ohm and 1 ohm has less resistence then 2 ohms. with your kicker amp it probly only 2 ohm stable so running a 2 ohm load on the amp will get the most power out of your kicker amp. if you ran a 4ohm load on the amp insted of 2 you will loose about 1/2 the power it can put out. ------------- 87 ramcharger eclipse CD5000 2 15" memphis M3 kenwood 900rms mono amps

Ohms also determines how long your amplifier will survive. Your amp is 2 ohm mono stable. You really need to follow the diagram I posted. If it makes you feel any better, each speaker is wired as a 4 ohm speaker.

yes follow the diagram posted thats the best way to wire it

okay so if i follow that diagram which i will and i use a mono channel amp lets say the ZX1000.1 wiring it that way does it put 500 watts to each sub? and with that diagram do i add the ohms together like lets say the subs are each at 1 ohm does that make it a 2ohm system and if the subs are at 4 ohms does that make it an 8ohm system

yes if you wire it that way you will have 500 watts rms to ech sub. if you hook 2 voice coils that are 4 ohm as + to + and - to - that will give you a 2 ohm load if you take 2 4ohm voice coils run one + to the other voice coils - then the remaining + and - to your amp it will be a 8ohm load ------------- 87 ramcharger eclipse CD5000 2 15" memphis M3 kenwood 900rms mono amps

so which situation do u have laid out in your diagram the second one where its both positives to the positive terminal and both negatives to the negative terminal so that it would be an 8 ohm system

im sorry if im being annoying about it but im just not understanding what your saying i guess im not really sure how a subwoofer is set up with the voice coils and all and the ohms

hey i forgot to tell you while we was on the phone but you only need a kicker ZX750 to run thos subs a zx1000 will be to much. so if you do use a 1000 be carfull because it will be to much power. ------------- 87 ramcharger eclipse CD5000 2 15" memphis M3 kenwood 900rms mono amps
