Subwoofer Recommendations

[Dtanous 0]

I am a novice and am looking for some suggestions. I have heard a lot good things about Sundown subs, looking at the website I am similarly impressed. I have a Toyota Tacoma Double cab and am looking to put a modest sq system in it. I have jvc double din and alpine s series component and coaxials in place. I have been trying to research a sq sub for the low end. I was going to use a single 10 in a Tacotunes enclosure ( 0.55 cu sealed with a 5.5 in top mount depth enclosure). And powering with a 5 channel amp, either re audio or alpine. I have been looking at the e series and the sd-2 series. Which sundown sub would be the best choice for a sq sub? I appreciate any suggestions?
