I currently have an infinity basslink in my honda accord ex wagon. It sounds fine to me but I'd like something louder and lacking the dropoff in low-end frequencies that the basslink suffers from. I was going to buy two Inifnity kappa perfect 12.1s but now I'm leaning towards one 10w7 powered by a JL 500.1 amp.
I listen to mainly IDM (aphex twin, autechre), speed/thrash/black metal (slayer, dimmu borgir), trip hop (björk, portishead) and a little bit of rap (outkast, aesop rock).
My question is just how much improvement over my current system is one 10w7 going to provide? And is the improvement worth spending upwards of $800 on?
