What's up guys and gals? I have two kicker L7 12's in a sealed box. My question is what kind of amp would be perfect to power these? Also I'm replacing all the factory speakers in my 05 focus hatchback. Looking for 4 Super loud but High quality component 5x7's and an amp to push them. any ideas?

Before suggesting amps, is your sub a D4 or D2 ohms? Also do you have adequate wire size for your power and ground and have you upgraded your electrical system/

my electrical system is fine. Not sure what the gauge of the wire is, but it's 4 or lower, and I have an additional power supply for the amps. How do i find out if my subs are D4 or D2?

If you have a multimeter, you can test it at the terminal. If not you would have to remove the one sub to verify.

If you have 4 awg wires you should upgrade to 1/0 awg. Have you done the big 3?

K, the big 3 is not done yet, however i have an aftermarket battery already in place. I used to have one Precision power 15, 1100watt precision power amp, and lights never dimmed. I don't beleive that will be an issue, however if u still think it might then i am willing to invest in that and applying that to my car even with the aftermarket battery in the trunk.

I do not know how many watts of rms is your Precision amp. Either way, you are going to run at least 1500 rms of clean uncliped power.

You definitely need to upgrade to 1/0. Once you upgrade to bigger wires, you may be able to get with a stock alternator but make sure to monitor any voltage change carefully.
