a high power amp.. thats listed on amazon(40) of them all for under 139.00
it'll power your subs. but don't expect much.
I'd get a good 4-500 watt amp first..
just because an amp made 870watts at 1khz (way about a subs range) means nada..
look at the amps home page, it's a full range mono amp.. 10-20khz
pushing that 1khz test signal at 870w is easy as pie compaired to pushing 870w of 30hz bass.. it might work fine as these trucks cabs are so small, you'll never use 870w while sitting in it..
if you're just looking for tha phat boom. it'll work.. and if used while your in the truck.. never be at 800w output. if it is, I'll bet of it shutting down.
if you're looking for nice tight bass.. thats not muddy.. it might have issues..
the flat 10"subs don't need much.. but don't expect that "hit" out of subs that don't move allot of air..
for an amp thats under 130.00 it might be worth a try..
I found years ago there is a reason jl audio/fosgate/etc mono blocks are not cheap.
but my 500w fosgate mono block would be overkill in a truck this size.. as it's a true 500w rms at the bass end 15-250hz not a rating at 1khz thats meaning less to an amp that see's bass only..
give it a whirl, worst thing is you'll have an amp to c/l
good luck..
