Assuming I buy these three things, here are my questions.

Currently I have a CDA 9851, I want HD, so would this deck fit in my car? (Honda accord 91 ex)

Then, how would I setup the sub with the amp? The sub is Dual 4ohm VC, so would I set it up at 500 watt RMS x2 at 2ohms? Or, 180watts bridged x2 at 4ohms? Or something different?

I am not an expert clearly, but I can figure it out. I just need the best option so I can mount and hook up everything accordingly.

Thanks

Answer 1

500 watts x 1 at 2 ohms

deck is single din it should fit in all cars
