Clean-RS4 Sub Installation

[CanuckRS]

After vacillating over which components to use and how to get the job completed, it's finally done.

Equipment:

Sub:Hertz HX250



Amplifier:Alpine PDX 1.600


I was contemplating building the box myself, but common sense finally kicked in and I had a local place do the work. I'm glad I went that way as it only took from 9am-5pm for them to complete the job, with some minor work to tweak it the next day. If I had done this myself, I can guarantee it would have taken a few weeks and not been one half as good quality.

Here are some pics, enjoy...

BEFORE INSTALL



AFTER



I cut out some of the styrofoam for the Alpine amp, which is quite compact and now sits perfectly on the right side of the trunk under the carpet. I wanted an OEM replacement for the sub that sat in the rear deck, but there is no such aftermarket sub available to fill the bill. A free-air or infinite baffle sub would require making the trunk airtight, a real pain the butt. The simplest way to get good quality bass is to use a sealed box with the appropriate subwoofer. The most logical place IMO to fit the sub box is the left side trunk cubby.



The install is not perfectly aligned as you can see and i am going to have them fabricate another frame for the opening as I am not fond of the square one they created. They wanted to put a cloth fabric over the opening but i like the look of this sub. I am going to get them to make a frame with a circular hole in the middle to show the sub itself and the frame around it, that should look good.



The key with this install was to maximize trunk space afterwards and all I have lost is the cubby hole on the left. I can live with that.




And btw, it sounds fantastic, the car finally has a nice bass kick that can be modified to taste with the gain control. I highly recommend a sub mod, it adds another dimension to all audio heard inside the car.

And all this wired to your stock deck ?

i dont like how that looks :(

why didn't you go with the TW5??

I think it looks nice, a buddy of mine with an s4 has 2 garbage subs in a massive enclosure that takes up the entire trunk from when he bought it. This gives me the bug again to do the same thing.

This looks great! I want to do this. I have a ported box that takes weighs sixty pounds and takes up half of the trunk. Im wondering how the sound is. Did you seal the sub or leave it open to the air?

Initial reasoning for the TW5 was it's thin size for the rear deck, but:

1. it's not an infinite baffle sub
2. it's not thin enough to fit the rear deck
3. it only comes as 13" right now which again would not fit properly. stock is about 10".
4. ridiculous price, over $500 i believe.

A 10" sub is a perfect size for that spot.

All you need is a good quality 10" sub and a proper amp to power it in that spot and you're good to go. I'd hate to lose the ability to fold down the seats for cargo. I was worried 10" was too small and it wouldn't give me enough bass...boy was i wrong

Mind if I ask how much the shop that fabricated the enclosure charged you?

x2
Can we actually get an itemized breakdown?

[bigredx24x]

that is sharp! nice work!

[whartung]

looks great. I know that if i had a grand or two burning a hole in my pocket I'd do this.

[Quattro]

wow that 10" sub looks really really small
how does it sound?

the cost for the enclosure was $400, then there was the sub/amp/wiring/fuse/etc...
total was around $1500.
not cheap, but i had an itch that needed scratching.
