Default Nate's Audio Quest

Howdy guys, figured this was a good place to post up updates and (mostly) questions on car audio stuff.


I'm mostly shopping for used stuff (bang/buck is my top priority). I'll probably be posting links and/or descriptions of stuff I think I want to buy.

Current status:

Soldered a headphone extension cable into my stereo. The two pins I used are the back-sides of a ribbon cable that runs between the CD player board and the receiver board.

Plugged in. Note the use of two cables .

Here the stereo is installed. It is the stock unit out of a 2005 Subaru STI. I got it for free when the PO upgraded. My 1999 stereo was crapping out, and generally sucked anyway.

Stealthed-cable until I drilled a hole in the coin-holder.

The plan. I already have this drilled out and a 3.5mm jack mounted (crapily) to the back side. I'm still trying to figure out a more secure way of holding the jack to the back of the coin holder. Every time I plug in the cable, it just ends up pushing the jack away from the back of its mount .

Fair price on the equipment.
How are you going to hook up the amp to the deck? Should've gottan an Alpine deck or something rather than one from an 05 STI.

Well you can't beat free. I have an old Sony Xplod system, but its probably not worth the money I'd spend on a harness. It has two preouts I believe (maybe just one sadly).

Is it going to be too hard to splice it into the stock harness? I don't know any other way of doing it with a stock unit.

I don't know much about audio, but a few guys here do. Namely pbasil, pioneerisloud, lautinjr, eric, and Chipp.

You can get wire harnesses that clip into the stock one, and has cut wires so no messing with the factory wiring.

Subscribed, and I agree with Eric. Grab yourself a factory wiring harness adapter (can be found at any local audio shop, and Wal Mart carries some). They're around $10-15 depending on the car. That will plug directly into your factory wiring harness, and give you all the wires as just bare wires. Then just splice into those .

If you're using a factory head unit, you should look into a sound processor or Hi Level Converter to hook your amp up. And the prices for the sub and amp are okay. I've never personally heard either, so somebody else will have to comment on that.

EDIT:
According to the specifications, the amp and sub are pretty decent, and well worth the $250. The ONLY problem I see with it, is that the sub is dual 4 ohm coils. You need dual 2ohm coils to get the most out of THAT amplifier. You might want to look into a different amplifier, one that has 2ohm power. You could run one channel per coil (300w RMS x2 @ 4ohm), and that would net you about 600w RMS to the sub. That's the only way that setup will work properly. The sub only handles 500w RMS....so yeah, they can be matched up to work correctly with each other.

Make sure you grab at LEAST a 4ga wiring kit for the amp, and at LEAST 12ga speaker wire for the sub. Look into ported box designs too.

Thanks for the responses guys.

So pio, is it OK to go cheap on a high to low level converter? As in ebay cheap?

Also, you say its well worth the money, but would there be a comparable 10" I should get instead? I'm just a bit concerned that the 12" won't get me a lot of quality over a good 10," which I should be able to find for the same price, right?


edit: kind of like an Alpine E10 for $55 shipped? 250 watts RMS at 4ohm.

I honestly think you should look into a halfway decent head unit first. Amplifying a crappy signal, is only going to hurt things later on. You COULD use a line level converter. They're all roughly the same, until you get into sound processors....which are around $70-80. At that point, you might as well buy a head unit. The Pioneer 3200UB is $125 online, $130 at Wal Mart.

If you're going for a SUPER cheap sub...the Phoenix Gold RSD 12's are on sale at SonicElectronix for $45 each right now. If you've got the cash to start a build, THAT is where I would start. Those subs are absolutely KILLER in that price, that's like $200 off retail. Those are powerful subs.

And if you're only going single sub, I honestly think a good 12 would be better than a 10. 12's have more cone area, and they have a tendancy for hitting lower. The entire point to a sub in a SQ car, is to have it pick up the notes your speakers can't do.
