I need help installing a kicker key 200.4 amplifier!!! I’m in a 2020 Corolla LE. This is my first DIY install and it’s a lot harder than I thought!! Here’s what I’m working with… i’ve done the first step, but that’s about it, which is getting the power wire from the engine bay into my cabin through a rubber Gromit. Does anyone know a way I can somehow either install this or get in depth help without spending an arm and a leg?!😂 I’m so excited to hear this amp but spending 350$+ for an install is kinda nuts to me
