Fi SP4 18 amp

[ncc74656]

I currently own a ZX2500.1 kicker and originally i felt that this was not enough power so i was thinking of upgrading to a crachendo amp but ive heard that they sound bad when running at 0.5ohm. im not sure what amp is best and what i should use for this sub. the kicker cant do 1 ohm so i was ordering a dual 1 ohm SP4 so i could start it off on the kicker and then give it more power at .5ohm on a better amp if needed.

I want to maximize the power of this sub so i want to fully power it. will the ZX2500.1 come close to fully powering a SP4?

what amp should i go up to? id like to sell the 2500 and buy a new amp for maybe 150 over its sales price. just to give you an idea of my price points.

thoughts?

i order my SP4 tomorrow. should i order a dual 1 ohm and keep the 2500 or order a dual 2 and buy a more powerfull 1ohm amp?

Buy the 2 ohm sub and get the aq3500. Perfect set up, fully powers the sub with no problems.
