with a budget of $300 and brz1200 he might as well go with something bigger than sa. Like AQ hdc3, Sundown Z, DD 3512 or anything in the range of 1000wrms. This way he wont overheat sub by playing it for a long period of time.
isn't there step down module you can hook up to alternator and run to 12v battery? i would stick with 16v system since you already have HO alt and batts
I had same problem with hifonics brz1200. Was getting really hot and one day magic smoke came out of it.
Now, got similar problem with saz2500, getting pretty warm after 10-15min of play time.
And I would laugh when you would complain about blowing subs. Nightshades are beasts, but I don't see them handling an NS-1.
they'll do fine on burps, on music just unhook 2.
Some of the stuff they show on TV is , but if it really happened to me, let's say haunted house, i would just burn the house down and let insurance cover it. You know "accidents" happen.
btw, there is new episode on syfy.
