Sponsers: Rough price quote for custom sub enclosure and sub/amp install lexus IS
 

Sponsors,

I'm in the process of purchasing a lexus second gen IS, might be a couple months away. Anyways, i'm looking to upgrade the Mark Levinson sound system on the car, well, actually just the sub woofer. I need to know how much money I should be allocating towards the installation (as the rest is going to a downpayment). Here's roughly what I need done:

The image is of a 12'' sub, but i'm probably looking at a 8'' or 10'' JL W7 or some type of shallow mount sub (I would like to keep as much of the small trunk space I have available). I also have a JBL 600W monoblock amp that would run the sub. I want the install to look clean like the one in the photo. The IS with Mark Levinson sound system has a amplifier already in the trunk so it may be possible to pull a signal line from there with the use of a speaker to RCA converter?? or just run it from the existing speaker level line that's going to the existing sub? I want to run the stock deck which has navigation.

Roughly how much would it cost to do a amp/sub install such as this which includes I guess a custom box and then a baffle or whatever you call it to make it flush at the back of the trunk. And then obviously run the amp power to the battery under the hood.

Thanks for any info you could provide.

We are an authorized JL Audio Dealer and I have 10W7's on special! Come see me for a quote! We can do your custom trunk setup.

If yours is the Mark Levinson system that means you must have Factory Navigation? Theres a trick we can do on your System too =)
