how to wire 2 amps? on 2 subs

[dannysaucedo25]

I already have a hifonics 1700 and want to wire a DC audio level 4 to it ... And I want to get another amp and sub.. Would I need to run another power, remote, etc..? Would I need to wire it the same as the other one? Also would would be any advantages or disadvantages from getting a 15in sub or a 18? In a sealed box

first off. keep everything the same. so if you get another sub and amp, get the exact same sub and amp. same goes got the box. remote can be daisy chained from the 1st amp. as for power, that depends on your setup. you need the electrical to back up all that power. that means a good alt and extra batteries.
