Help needed connecting an aftermarket amp to the new 2021 yamaha SE boats

[lightweight]

guys . I need some help . however I'm in north NJ and I haven't found anyone that is able to help. i will be adding 4 new 8in tower speakers from Skar audio as well as a 4channel 1000w RMS Amp to the stock wet sound system that this boats come with. however the problem i found is that i was not aware that the OEM amp has all plugs or temper proof. is there a way to connect or piggy back from there so i can connect 2 RCAs and a remote wire? I've ran all the ground, positive and all speakers wire already but only thing missing is connecting RCAs' and the remote wire.
is there any adapter that i can buy or anything out there? has anyone experience this? your help is appreciated.

Just tap either the input or outwire of the factory amplifier using speaker wire or 9 wire, then put RCA plugs on the other end of the wire.

1. Get some RCA tips: https://www.amazon.com/Kicker-KISL-...ocphy=9012156&hvtargid=pla-382850056200&psc=1

2. Look for the plugs from the amplifier that are the outputs to the speakers.

3. Connect the tips to the output wires of amp using a military splice.

4. Connect RCAs to your amp.
