the subs are very different all together. It would depend on your design goals. The sa is designed for a ported application. The DD appears to be designed more towards a sealed application, with a glance at the specs. The build quality of the SA is without a doubt a win. I would do the SA8/AQ combo (unless you could do a VFL100.1)Run off an AB VFL80.1 more then likely or AQ1200D...havent decided
The sa v2's would be new and the 1508's would be used with CF caps...
could be they just like a little bigger box, IDK, I have not fooled with the DD1508, which is why I was cautious in wording my previous post....don't get me wrong though, if you can get the used DD's cheap enough to flip for a profit, go for it..It will be ported and more then likely built by a member on here...Subs and amps more then likely purchased from a member here as well...
As for the amp the 100.1 is 15" long and there is just no way I can do it without it sticking out from under the seat too much. Hell I screwed up my measurements with my KS300.2 I thought that was 13" but its only 11.25" and the rca's stick out just a tad...
BTW nearly all I have read says the Complete opposite of the DD's...
You do not want to mount the amp to something prone to excessive vibrations...there have been many amps fail from being mounted to a sub box....a big gamble.I have been thinking about putting the amp on the box itself then I really dont have to worry about the size of the amp but can it go there? Also how easy would it be to unhook incase I needed to use the space?
Yeah I read that but still have to ask lol...You do not want to mount the amp to something prone to excessive vibrations...there have been many amps fail from being mounted to a sub box....a big gamble.
on this i'd say you are wrong ,the dd woofers are very solid and i've seen them take more than 1000 rms each.only cosmetic difference is the sa has a cast basket where the dd is a steel stamped.but the dd's are direct leads too.the dd's love ported boxes way more than sealed also ,tuning for both subs should be at 34-35 hertz tho.the dd subs will be louder in the end .id have to say the sundowns build quality is definetly better then the dd1508, i have a 1508, sa8v1, and sa8v2. all very solid woofers tho.
