Background: I put together a homemade subwoofer using an old monoblock car amplifier (12VDC 300W), 1.5 Farad Capacitor (inline between the power supply and the amplifier and power supply) and a 600W ATX Computer power supply. I modified the power supply by wiring in a SPST rocker switch, cutting off all the connectors and wiring together all of the ground and all of the 12VDC+ wires which are connected to the amplifiers respective ground and 12VDC+ terminals. This setup has worked great for me, but now I want to take the whole thing wireless so that I can control it from my Harmony Universal Remote.
My Solution: I purchased the following IR receiver/relay setup on Amazon (https://www.amazon.com/gp/product/B06XHHNG65/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1).
The Problem: I am not a professional electronics engineer. The relay is marked as 10A 250VAC, 10A 125VAC, 10A 30VDC, 10A 28VDC. Since the Amp is rated for 300W, I think that means it can draw a maximum of 25A. Am I correct in my understanding that this switch will not be able to handle more than 10A? If this is true, can someone point me to (a link maybe) a relay that I can slap on this board after de-soldering the existing relay? Would that work... if I de-soldered the 10A relay and soldered in a 30A relay capable of handling 12VDC?
A side question is whether I even need the inline 1.5 Farad capacitor. I used this when the setup was installed in my car, but I'm not sure, but I'm wondering if given that I'm using a computer power supply and not a car battery that maybe I can just remove the capacitor.
