Cheap bass

[Synack]

Normally I don't go the cheap route but after spending near $1000 on my NISMO to get a new radio, 4 front speakers, XM, steering wheel controls, etc; I still basically don't have bass. There's a little but not enough.

The stock 10" sub that was in my Cobalt was perfect. Being that that was a coupe that had rear seats and a trunk, I figure that a good 8" sub would suffice for the Z.

What would be the best and most cost worthy method of getting bass into my Z?

I listen to a lot of electronic music, and other types of music as well and they all require bass lol.

Thank you for your posting!
