Here are a few quick pictures of a Custom 350z subwoofer enclosure I have just finished for a customer, He uses his 350z as a show car and is running in the region of 500BHP, so he wanted something custom made to start off his audio install and I came up with this.
It fits under the rear strut, houses 1 - 10INCH JL Subwoofer, and the rear has a fully incorporated AMP rack, as you can see I have made both sides to sit under neath the strut so it fits flush with no gaps and there rear amp shelf is joined to the enclosure to give it a tidy finish. Once fitted the two un-carpeted sides can not be seen, These can be carpeted if you desire, however our customers don't normally ask for it to be done as its pointless.
The sub fires towards the rear window and the amp rack sits behind the drivers side.
As you can see, all our products come with the “Made by Custom-CreationZ Engraved Logo"
I will have pics of this fitted in the next week or so for your enjoyment.
This is a custom made box and prices vary depending on designs feel free to get in touch for a quote.
