Yaris Sedan Deadening and Sound system upgrade

[packetrace]

My HU is a kenwood mp-345U ...only one rca output....

I was looking for Alpine Type R for the sub....they look great and i had nice comment on them

Audiocontrol i mean...what you have already been talking in your thread....the one you have bought.....do i really need this

I'll go for the ported sub boxes

deadending i was just saying thank you...i will look at foam cld tiles and MLV i'll you use thos three

Battery....i've seen people changing the battery for a more powerful on and adding the big three of course but not changing the alternator and adding a second battery......perhaps...how much for an alternator of 200 amp ?

thank you!!
