Let me start this out by saying this is not my car, but it belongs to my brother. The goal with this system is to add a little bass to the car that seemed to get washed out at high volumes with the stock system. We are also on a tight budget and wanted to keep the cost of everything when we were all said and done under 500. Now he is thinking of upgrading mids and highs

For starters we went with a pioner deh 3300
Here is a picture of it installed

Here is a picture of it next to the stock radio.

For wire we went with Knukonceptz 0 gage CCA. Wiring it was not fun at all. It took about 3 hours. I wanted to avoid pulling up the seats at all cost because it has been known to throw a Air bag code in these model subaru's. but after trying every way imaginable it came down to just ripping all the seats and carpet up. Thankfully the airbag light didnt come on. Every pannel I pulled off was a fight and is by far the hardest car I have had to run power wire through

I decided to start from the back to make sure I had enough slack back there. I ran the power wire and turn on wire down the left side of the car and the Rcas down the right

The RCA's were much easier to do and didnt require removing the seat here is how I ran them

We plan to throw the 8 on a audioque 750

Plans for the future are to do a full layer of Audio Technix sound deadener and a few pieces of Cld tiles.

Then replace the front stage components with a pair or hertz, morels, or cdts havent quite decided yet and amp them up. Hopefully will post pics of how the amp is mounted and everything soon.

Looks pretty good to me. It seems like you guys have a decent amount of tools to work with. The only thing I would have done different was some dowels to tie the top and bottom pieces together, but I'm someone who likes to go overboard with bracing. I see 45s in there as well, pretty advanced for a first time build.

Its always funny to see the different ways of how people make the slot- some will notch the baffle like you guys, some just cut the baffle short to make up for the width of the opening, some will just cut out a whole rectangle in a full width baffle....many ways to skin a cat.

Kind of what the goal is, he told me he wanted all out sound quality so I showed him what went into one of those builds and he quickly changed his mind . His last car was 2 sony xplode 12s on 400 watts with kicker coaxial all around lol. I think this will give him a huge improvement in sound quality and spl.

Right now its just a waiting game for the sub to arrive. I will hopefully post a video up and pics. Im really interested to see just how loud one of these will get on just 500 watts rms.

Nice he is not too worried about numbers though but It would be interesting to see how it did in a trunk car on 500 watts.
Im not too familiar with meters but would it show us where his car peaks at and how flat the response is from it? it would help out knowing that lol.

I think it would be very beneficial for forum members to see it metered and we will be able to see where the car peaks at and how flat it plays. What I did for some personal testing was take a 15sec average and plot the reading in ms excel then make a line chart to show how the output goes up and down throughout the freq range.

We had quite a few problems actually droping the sub in place and had to do some sanding on cut out for the sub for it too fit. The mounting rings and the edge of the basket are way to **** close together take a look at the pic there is that much clearance all the way around

Probably but he was sitting at 14.2 volts at the amp with the car on and parked doing sine waves :) soo really cant complain. Im not sure if the 0 gauge helped at all but it gives head room if he decides to upgrade. Right now a T-line is on the drawing board for designs and im sure more dicking around with the amp which doesn't seem to be working correcty

I went for about a hour and a half drive with it, i think the spiders were really stiff, because it got noticeably louder as the drive went on. and i got to hear it a lot more without you turning it down every 2 minutes telling me how i should have gotten a 12. The 0 gauge is fine the real mistake was the twisted pair 10 gauge speaker wire, never again.

Yea everyone this is his car ^. and I think the real mistake was trying to cut the speaker wire in your hand with a razor blade.

It was the Knu Konceptz double shielded double twisted speaker wire stuff its thicker than 0 gauge and we don't have any strippers that will go up that big. So he thought he would use his hand as a cutting board and ended up with a trip the E.R. and some stitches.. probably the dumbest thing I've witnessed but we all **** up every once in a while

If you're still up for metering we are still interested, does it have to be over a certain Db for the meter to pick it up? this thing is kinda quite so don't expect to be blown away but you gotta remember its only 1 little 8 off of 500 watts. We could do a before and after sound deadener too I think that would be interesting to see. He just ordered 75 sq ft of audio technix.

Our goal is sound quality though so if you could do that thing where it graphs it in excell and shows us the cars peak and everything that would help us out

lol wow, lesson learned I guess.


I believe the meter will register down to about 110db. It should easily break 120, I'm expecting it to be around 130 at the headrest and maybe a little higher in the kick on the dash.

I'm free after 4pm today and before 4pm tomorrow. just me me or something, I'll prob just be wasting time on here in between trying to do schoolwork.

little update on how it does Spl wise thanks to Kushy Dreams for metering it here are some results
1 sundown audio sa-8 v.2 dual 4 wired to 2 ohms on a audioque 750.1
130.2db at 41hz sealed at the dash
also did a 128db at 51hz and 27hz.

Yup 27h kinda blew my mind it hit that low like that also from around 25-50 the sub was completely flat rising by 10th's of a db at most through out that entire range

04-21-2012, 11:25 PM
No prob, it was nice meeting you guys.

The 128 scores were at the headrest (meca style) on drivers and passenger side with the passenger door open. I was very surprised at how well it played and how strong the low end was. It played well into the mid to lower 20s with authority, even with a box tuning and fs of 34hz. This was the first 8 I have ever heard in person, very impressive for the size and power involved.

I could have spent another hour moving the box around trying different things with interior pieces lol

Quick little update, received the deadener in the mail a couple of days ago and got around to applying it yesterday. We learned that the mounting depth for the speakers is extremely shallow. kind of a bummer but mounting brackets will be made
Here it is 75 sqft of audio technix

we ended up using about 2/3 of one 25 sqft roll to do both front doors we plan on doing the back doors and the trunk floor. The difference this stuff made on the front doors was unbelievable anyone contemplating weather they should deaden their doors do it. It got rid of an anoyying humm he had in one door, and really brought out the midd bass even from the stock harmon and kardon speakers

Yea it was a champ when it worked but it blew on me. Gain not properly set .. my nooby mistake a long time ago

Im wondering if we should deaden his rear deck im kind of afraid it will make the sub not as loud in the cabin. but we are removing the stock 8 inch speaker that is in the rear deck so there will be an 8 inch blow through into the cabin that will be opened

Looks good, the only thing I would've done differently is in the box. I would've routed a 1/8" groove on the back side of the front panel around the oval opening and sandwiched the carpet between the 2 panels. That would clean up the inner edge on the sub baffle. But again, looks great.

Looks like a trunk lid is in need

Wrapped the spare well Decided not to do the part where the tire sits because the weight from the spare and amp rack should be way more than enough to keep that pannel from ressonating. IT also had a cote of liquid deadener from the factory.
