All in the box. If they can handle the power the box will make the difference

That amp can make a good amount of power, more than most factory electrical systems can handle. What does your electrical consist of? Then decide how much room you plan on using for a box. Once you have the box size get a budget and we can make suggestions.

what box were you using? If its a small sealed box, there's your problem. IF a pair of 15s arent louder than a pair of 12s its a severe flaw in your install and enclosure design. IF you dont address that, you wont get loud no matter what sub you buy. In this case its not the sub's fault this is clearly user error in terms of an improper enclosure/acoustical loading.

Build a new box for those 15" L7's

4.5-5cf each tuned to 34hz with at least 60sq" of port and they will slam

so both the box and the ohm loads are messed up. Yes thats a complete garbage box. Without a properly designed custom box you wont get anywhere.

Never buy any pre-made box ever again and get one built by someone who knows how to get loud.

Thats about half the airspace the sub actually needs, its being strangled to death. I guarantee that a single 15 wired to 2 ohms in a properly build 5 cubic feet NET box will absolutely destroy your old setup.

no just sell one L7 15 and build a proper box for the other and just run one, You will be surprised at the massive difference. A 6000$ sub in a sh*t box will be beaten out by a 20 dollar flea market sub in an amazing box easily.

You NEVER look at peak watts always RMS.

Sell everything else besides the 2500.1 and kx850.4 and get yourself a proper box built would be the main goal here. If you disregard the box, all hopes of getting loud will go down the drain no matter what subs you buy.

i think the 2500.1 is too powerful for that sub 1000w rms they said 1200rms is perfect for it that amp is 2500w rms

just because its 2500 watts doesnt mean you have to use all of the 2500 watts. You can directly adjust how much power the sub sees with proper gain adjustments via multi-meter

What vehicle is this setup going into?

a dodge durango with the 3rd row seats removed i can buy a professional box as big as it can be

measure in Length x width x height on the space you are willing to give up and we can give proper sub recommendations. If you want loud, kicker isnt the way to go.

ok so i get new sub/subs 12" re or ssx 15" or one 18" and keep the kx850.4 for mids and highs

like 40 l x 40w x 22h should the subs face front top or back
