Default 04 rs audio thoughts on a budget

I am looking at doing a simple stereo upgrade in my 04 rs sedan as the stock speakers suck. My plans so far are:

Deck: Sony CDX-GT56UI (came with the car)
Fronts: JL TR600-CXI (I have them)
Amp: JL Audio JX360/4
Sub: JL Audio 10W0v3-4

I listen to a little bit of everything from rock, some rap, some dubstep, some country, just All over the board. But I would like a balanced system able to reproduce a wide variety of music accurately, without distortion or loss of bass even at full volume.

I was thinking run the fronts bridged at 4 ohms then bridge a pair for the sub at 4 ohm. I can build a box per JL specs I would do a ported box. I do not own the amp or sub but does it look like a pretty decent system?

I was thinking down the road pick up a set of JL TR525-CXi for the rear and run them off the deck if I want and maybe add a touchscreen pioneer double din down the road. Thoughts?

when you say 'budget' are you trying to say:

a: 'on a limited budget?' or

b: 'what should i be budgeting?'

if you're talking about a 'balanced system,' it should include noise control plan, too. you thought about that at all?

I have not when you refer to noise control plan does that mean sound deadening? I am still newer to stereo planning. This would be my first install involving more than a sub/amp combo.

yes, sound deadening/ noise control.

even a little affordable noise control can make a 1dB to 2dB difference.

If you can reduce noise by 1~3, its effectively the same as getting almost twice the power/loudness from your system.

you said it was important to play the full volume range, so I would start by trying to make your system have to work less hard to compete with car noise.

Your speakers are pretty efficient.

The amp is a good choice if you're going to keep the Sony headunit, because the amp has independent crossover filters. You'd basically run the front speakers off 2 of the channels, then run a sub off the other 2 channels with the filters turned on.

for basic noise control, I would take a small pillow with you and drive around, and on the highway.

turn off the radio and try to put the pillow over where you think noise is coming from, and decide where you could make the biggest difference. Pick the 2 biggest differences you noticed.

Then, in addition to that, you should place butyl mat stuff on the door around where the speaker goes, and behind the speaker inside the door.

Okay I was actually looking at getting some raamat to do the front door and trunk, how much would I need? Its a 04 sedan.

For the sub and amp does that look like a decent balanced system? I was wondering if the amp was underpowered.

the trunk will matter less than the door, but if you can afford it, both are good.

I would still focus on identifying where you think noise comes from specifically first.


as far as gear, its subjective. For some thats over-kill. For others it barely scratches the surface. The reason I said deal with the noise control is that it will help whatever gear you do go with to work better.


In that configuration you gave, I would not use the amp on the Sony, and I would not run rear speakers. I would run the fronts and the sub off the amp.

mebbe aaron will chime in too, but i'd say...


you're putting some on the surface where the speaker is mounted. I'd say at least 2~3" all around the hole.

and then you're putting some behind the speaker on the body panel of the door. So about 2~4 sqft a door.

Its not too much, and if you can afford more, go for it, but thats a start.

I'll post the same thing i posted on ca.com
Owning a 05 i can tell you 1 thing.
Sound deadning.

Everywhere.
Trunk lid full coverage.
Take all your trunk carpeting out.
Do inside the rear quarters/wheel wells/entire trunk floor.
Also do the whole front door. Inside the door skin/skeleton.

I added around 50-60 sqft of deadning to my car. It is 100% necessary considering our cars are made of tin cans.

Check out zillamat on ebay.

My friend has a 161+db tahoe and did his entire truck with it with 0 issues.
has been in for ~3 years or so and has not had anything peel or fall off etc.

Pillows dont block road noise... much like CCF neither does matting.. it deadens the panel...

MLV or mass loaded vinyl does however block and you car has some stock... the interior firewall blanket. .

Poor idea

AFA basic sound deadening its alreay been touched on...

Adding some to the inner door frame (tough its got many folds for strength) helps and adding behind the speaker helps a LOT.. but you dont need 4 layers of peel n stick like me...lol...

Sound deadener showdown outlines 25% coverage with CLD tiles (peel n stick)

So that being said, you can buy door kits and trunk kits to play with...

Or you can buy a roll and just go...

What it comes down to is how far you care to take it... ive taken it pretty frikkin far...lol

I think you misunderstood me.

A pillowmost certainly attenuates noise (just its thickness will tell what freq it can muffle), but the suggestion is its just the easiest thing people have lying around to play with/test out that doesnt require more effort/comittment to install.

and the butyl mat around the speaker is not for road noise, its for the mechanical vibration of the speaker.... :/

There is not a butyl anything on or near the speakers of these cars...

However, if you pull the carpet back and look against the firewall there IS an MLV/carpet padding pad againdt the firewall...

If you are talking about decoupling the speakers in the stock doors youd be silly too

This is what I ended up with:
Deck: Pioneer F700BT
Fronts: JL TR600-CXI (I have them)
Amp: Mtx 8000 (had it)
Sub: 10' type-r new model 1000rms in a 1.25sq ft ported custom box

Got a killer deal on the type-r or I would have went with something different. It is stupid how much it thumps I turned it way down and the JL speakers sound so good.
