Now get under your car and look to the right of the muffler heat shield you will see two silver bolts and between those two bolts is a hole.. Place your cardboard template and mark where you need to drill your hole for your toggle bolt

Theres mine... Cut out this hole aswell and then your ready to trace your new template to the plexi glass..


After you trace your pattern to your plexi glass twice (one for leftside one for the rightside) and cut them out using a Jig saw... Mount your speakers in the new plexi mounts you just made, and hook up your wires. I would give yourself about 6 foot of speaker wire each speaker..

Place your toggle bolt threw your hole in the plexi then into the hole on the frame between the two silver bolts like so.. and tighten the screw untill secure.. Do not over tighten!! You could break the plexi..

For those who don't know this is a toggle bolt

Run your speaker wire to this bushing.. located under the exhaust heat sheild... this will lead to your trunk under your spare tire... Take this wire and run it to your amp and your all set!!

Tips on your amp turn down any bass boost and set the it in the middle of 50hz and 150hz...


I hooked up my amp's remote wire to a toggle so I can turn them off and on whenever I want..

awsome... ty.. now i can wash my car with music without having to drag my stereo down...

hmmmm......and the point of this is????? music while washing???? takes about 30 min to wash a car thoroughly.....after that......roll the windows down to dry/clean/polish/wax.....

This mod is normaly used for big trucks ie: Suburbans, Tahoes, ETC in their case they can do 4 speakers 2 in the front 2 in the back, being we drive small compact cars I did only 2 in the back, It doesnt really matter if you put them in the front or back they are so loud you cant tell where its coming from and the sound comes out of the sides of the car anyways, I myself couldnt do any in the front because.

1. My car is to low
2. There is too many working parts in the front for me to feel comfortable with it.

I just found the back easier / cleaner looking because they tuck inside.

very different if only I wasnt planning on air susp on my xB i'd do it on mine . I like the idea just very different , lol.
