Yeah, there are two subs, but I am still fairly happy with the results for a first attempt. However, it can certainly be improved on so I'll give major bracing a shot.

got dimming? lol

Yeah... extreme, everything's running off of a POWERPLANT of a battery (600 electrifying cranking amps). When funds allow, that's my next upgrade.

is this off of both sundowns? I say play around with placement as well! Another thing, the tuning like everyone has mentioned, I say high 40's but I don't know as much as a few people*cough Yuli cough *. Let us know the outcomes of this!! Im surprised at the 145 mark with 2 sundowns(if that is with 2)

try subs and port forward, and tune to mid-high 40's

Battery will make quite a difference as well. I would do that asap

Yeah, that score is using both amps. It looks like my next box will be an all-forward firing setup - I've been wanting to try one, but haven't yet since I had crappy results with my daily driver box firing forward... but maybe a higher tuning will be the key to success. I know its hard to say without actually testing, but can anyone give a ballpark on how big of a box this should be? If everything is forward should I make a massive box or a small-ass one?

Hopefully by then I can get a hold of a new battery too, but this week its back to school for me. Thanks for all the info so far guys.

What ohm load are the amps running? and are you running one to each sub or strapped?

Only 2100w, I thought a strapped pair were supposed to put out more than 4kw??? :dunno:

They do.
