Help deciding amp for adding sub to Non DSP
 

i'm going to get a jl steath box. which amp should i get? i'm looking for a stealth setup so want to mount it under the floorboard like:

i'm looking at the the following three. Can anyone comfirm if each one will fit in that space?? or any recommendations for other stealth mounting points..

alpine mrp-m500 (10-11/16"W x 2-7/16"H x 9-9/16"D)
JL slash 2 250/1v2 (10-1/4"W x 2-5/16"H x 10-3/16"D)
JL slash 2 500/1v2 (13-7/16"W x 2-5/16"H x 10-1/16"D)

my friend has a free kicker L7 that he will give me, i also might try that option to see if im ok with trunkspace... since i'll only have to pay for a sub box...


thanks in adance.
