I have a 2004 TSX AT with all the stock headunit and speakers.
But I figure out I want to get some more bass out of it.
My budget will be about $200.
Is there any suggestion?
I don't really know much about cars. so I was thinking to let the store to install it for me.
Is it true that if I change the 6'x9' sub at the back really helps to improve the bass?
Urgent.
Thanks for reply.

 

your not gonna get much more bass with a $200 budget including install
cuz ur prolly gonna have to get an amp also and install is around 50-150 for 2 speakers and amp instal

 

It wouldn't be worth the investment to replace just the 6X9s for bass improvement. At $200 I don't think there is anything at all you could do. You would need wires, amp, sub and installation. If you double that $200 you would be able to afford something that would add bass to your car. You could possibly find a deal at Best Buy or Circuit City for around $300, but you won't get good quality, just that extra bass.
