AA98hoe Posted March 31, 2012 Report Share Posted March 31, 2012 You say 2 3500s strapped at 1ohm so that's .5 per amp..depending on box your rise is going to affect wattage..I wire at .35 each and rise to 10hm because my box is on the small side 16cf for 4 -18s...so let's say in a perfect world 7k on 12v..id do ascendant havocs you won't have enough power for mayhems unless you plan to upgrade...do 4 -15s and common chamber means all subs share the same airspace...this helps keep down the overall size of box and you can make it a lil smaller..

Basson50 Posted March 31, 2012 Author Report Share Posted March 31, 2012 (edited) Yea that's ren it gets down....back to the op subs up port back should sound best don't go too high with box do common chamber tune mid 30s you should get loud His subs were getting hot fast tho! Could only play them for a quick minute each but he said the two rear ones were brand spanking new. if you get 4 of anything with 10k+ rms youre gonna be loud l I only have 8 to 9 k though from the tiny bit of knowledge that I have. With 8 to 9k rms I'd get 4 night shade 12's because they sound fantastic. Heard them and also if you dont want to spend that much money go with the SA-15's they sound clean too. If you want some loud ass subs and want to upgrade your electrical and amperage and get some DC' You say 2 3500s strapped at 1ohm so that's .5 per amp..depending on box your rise is going to affect wattage..I wire at .35 each and rise to 10hm because my box is on the small side 16cf for 4 -18s...so let's say in a perfect world 7k on 12v..id do ascendant havocs you won't have enough power for mayhems unless you plan to upgrade...do 4 -15s and common chamber means all subs share the same airspace...this helps keep down the overall size of box and you can make it a lil smaller.. When I had talked to sundown they told me they have these special rings in there subs that can Cut down impedance rise a lot.
