How much will it cost to have an amp and 2 subwoofers installed in my hummer h3?

i am going to buy subwoofers and an amp. how much will it cost to have that all installed in my H3?

Any suggestions of where i can have this done for a good price?How much will it cost to have an amp and 2 subwoofers installed in my hummer h3?it depends how much the amp and subs are going to cost and if the car hifi specialist shop will do a deal to get them fitted

i would tell the seller that you have got 800 bucks to spend on an amp and sub and a wiring kit and would you be able to fit them for free if i do decide to buy them from you,,

there is nothing wrong in asking,,

i would rather have a 800 buck amp and sub package than spend a 650 bucks on an amp package and another 150 bucks for fitting
