Featured Draining Power

[Grantttttttt]

I’m fairly new to aftermarket audio components but I have used them before. Recently I just got some new subwoofers for the car and they use a lot of power. 2000w to be exact. They work how they are supposed to but I have to connect them to my starter battery because I have no other battery. My main problem is that I come out this morning and go to start my car and it is completely dead. I have no clue whether I messed something up while wiring it in or if it’s a faulty relay in the radio or something. But my main suspicion is either the remote turn-on wire or the +12 power wire. Should I add some sort of switch to one or both of the wires? Should I rewire the remote wire (I just rewired the power wire)? My power wire is connected straight to the starting battery (with an inline fuse). I need some help, I am really confused with this.

My power wire is disconnected because it’s draining my battery.
Clamps on my battery because i’m charging it because my car is dead because my amp drained the battery.

Is your battery charging in the first place? Your poles look fossilized.

New battery. At least clean up the terminals. If continuing in car audio do the big 3or4 wire upgrade and go dual agm batteries with an isolator.

Sounds like your remote is connected to constant 12v source allowing your amp and power wire to drain your already hurting battery.

Piss poor advice right there. The guy is running a sub box with a built-in amp on 4 gauge and you're suggesting him to go dual agm? What a joke...

As asked above, where is the remote wire spliced? I would start by cleaning those posts, take the terminals off completely and wire brush the cables until shiny, wire brush the terminals completely and re-assemble. Add grease After the assembly to protect it all.
Keep in mind that in a lead acid battery, every full discharge sulfates the battery plates and weakens it.
