i love how everyone just starts saying subs to get. to the OP, What are you going for? is the a competition vehicle? Daily? SQL? SPL? Whats the Goal? If spl Your going to need a hella lot more power. Daily get more smaller subs as opposed to 18's or 21's. More heat dissapation and more...
Stock Electrical wiring is like clogged arteries, the big three is a stint to help the flow of the clogged arteries, a capacitor is cholesterol. Anything that doesn't generate power consumes and/or stores power. Your battery stores power. All a cap will do is store a minimal fraction of power...
I hope nothing bigger then a 40.1 comes out. just strap smaller amps.... much more stable... don't have to worry about over stressing the power supply..... or charging an arm and a leg for a proper power supply for 5kw plus. i think those IA amps are infinitely strappable.
there is no left and right in bass. anything sub 80hz should be mono, and unless you arerunning an a/b amp not bridged (why for subs I don't know) then the signal will always be mono. Plus I like a common chamber better, because you have both subs pressuring the same chamber and same port...
want to buy multiple batteries. optima d31s, spv70's, kinetic, powermaster. I'm not going to overpay so if your charging 250 a battery I don't want it. looking for at lease 4 or 5. will be running close to 10kw when all is said and done.
