Here my question that I have. I have (2) Kicker Comp 12'' Subs. There power handling is 300w Peak and 150w RMS each. I have them in a sealed enclosure and I have no idea what amp to run them with. I have been told that the Kicker zx-400.1 would work and I was told that it was to much to go with the zx-300.1. Someone please help me I want to hook this up and need help. Any other amp suggestions I even thought about these two amp?

Please Help I'm gonna go crazy.

 

If you want to run any of the amps you referenced, you need speakers that will handle the power. 500w can blow two 150w speakers. You can run those amps, just don't turn it up. Why not look for a 300w amp?

 

The kicker speakers I'm using are 4ohm. The max those amps I chose put out around 300 watt x1 @ 4ohms.

 

First think if you will ever upgrade to more or bigger subs. If there is a possibility go with the biggest one you can buy and have room for. There is a adjustability input level on the amp, you should be able to adjust it down to make your subs thump and not blow them. Set you head unit bass to 0, turn your gain all the way down, turn your stereo up to your usual listening level, then adjust your gain up till your desired bass. Watch out for the sub-sonic bass gains too. They can help in the blowing of subs if not dialed in right to, but they really help out in the deep bass department. Othere then that run what you like. Buy a good name brand and remember, you get what you pay for usually in the stereo dept.

 

Those amps put out 500w into a 2 ohm load. You said you have 2 speakers at 4 ohms each. If you connect them in parallel, you now have a 2 ohm load. If you turn up the volume, that 500 watts gets divided into 250 to each speaker.

the formula for paralleling the speakers is:

R1 x R2
-------
R1 + R2

 

The zx-400.1 will be fine. It's 400 RMS in 2 ohms...

Leon is correct, you have 2 4ohm 12"s wired in parallel...so they'll each get 200 watts.

 

Thanks for all the advice. After reading what Leon and DJMoose posted to me it made since. So I did some research on the amp I currently own from when I was running a 12 sony xplod on. Its a Pionner Amp heres a link about it.
