Need help!!!!

[Blazerslapp]

Alright this is what im thinking,for the poor boyz new build season is coming (TAXESSSSSSS!!!)

So im thinking of selling my xl 18 and buying 2 lvl5 15's (For right now it would be ran off the t2500 till i got money to get another t2500)

i would love to get 2 lvl 5 18's but i dont have the air space and dont want to build a wall.*BTW if anyone can find the air space for 2 18's in a blazer(Dont need my back seats)* i would love you but dont think it can be done

what it comes down to is i want more cone area

So what you think?

2 15's> 1 18 and ive heard that the 2 15's would be louder cause cone area takes the win right?

Yall know im still new to this shit

141.8 @35hz just seems hella low and i got a "Next to the audio store" box that a guy made with a weird ass port-The port goes up the box turns to the right goes all the way down the box,then goes down about foot the goes left and stops about half way-

i just want louder

Lend a brotha some help!!!! thoughts ect.
