sub/amp setup in a tj
 
I'm thinking of getting a sub for my tj. I would love to see pics of your set up. That would help me decide what I want to do. I was thinking about a small 8" kicker. But don't know to much about subs.:D

Buc Knaked 06-26-2008 06:37 PM

i have a Yj
and im not sure what to do with mine either pics would be nice

hey, i found this guy online, and recently ordered a sub box from him online... not bad prices, and good quality it seems. When it comes in I can give you guys more feedback, but i cant wait... Plan on using the yj style box with a 10" sub and amp

4.0l sahara 06-26-2008 06:50 PM

i went with the same speakers you have, and two alpine type-r 10" downfiring in the back... i loved having 2 subs and would do it again

Jma20a 06-26-2008 07:03 PM

what kind of budget do you have?

i have a pioneer p6900ub with sirius radio and ipod, infinity kappa plate speakers in front, infinity kappa perfect components in the roll bar, 10" audiobahn immortal sub, and temporarily i have a profile california amp(blew my nice amp a few days ago) as for pictures

for a sub is it better to have 2 ohm or 4 ohm? Or does it really matter?

4.0l sahara 06-26-2008 07:18 PM

What about this small kicker?

Jma20a 06-26-2008 07:22 PM

usually a lower ohm is better, if you get a sub with a duel voice coil there are more wiring options in terms of what ohm you are looking for. im sure tripp will chime in with all the wire diagrams to better explain.

with the amount of sound coming out of your speakers it might drowned out your sub. its rms power is a little low, and that sub is more for "free air" use. i would go with a sub that has around a 200-350 rms power.

4.0l sahara 06-26-2008 07:41 PM

This one?

no no no no. Ohms has nothing to do with being "better"..... at all. It simply tells you what resistance that particular speaker is. Standard resistance for subwoofers (in a car) is 4ohms. That's what most amps are rated at, for example when you buy an amp it will say 300 Watts (at 4ohms.) Look for a good 4ohm sub and a quality amp and let it fly! You will not notice a huge difference in sound quality between a good sub and a real expensive sub, so don't go too crazy. The biggest difference you will hear is from your highs/midrange because your ears are more sensitive to those frequencies- so spend a bit more that you think on those AND the amplifier. Junk amps make junk sound- they're prone to interference and have cheap crossovers inside. hope this gives you a bit more info than you had before...

that would work, it has a good power range, and frequency response.

How does one wire a dual voice coil sub to a single channel amp?

ok most would "prefer" a lower independence

What is better ported or sealed for the box?

depends on the sub, some work best sealed and some ported.

4.0l sahara 06-26-2008 07:58 PM

how do I know what would be better for that kicker? Arn't sealed boxes smaller?

Jma20a 06-26-2008 07:58 PM

this is what was written at the bottom of the "hands on research" page for your sub

Power Handling: The power handling specifications differ according to the type and size of the enclosure. The power handling specifications assume that both voice coils are in use. Note: Both voice coils in a dual voice coil speaker should always be connected.

Recommended Sealed Box Volume:

* Compact (minimum enclosure volume): 0.8 cu/ft; the woofer can handle up to 300 watts RMS (150 watts per voice coil)
* SQ (maximum enclosure volume): 3 cu/ft; the woofer can handle up to 300 watts RMS (150 watts per voice coil)

Recommended Vented Box Volume:

* Compact: 1.25 cu/ft; 2" x 10.5" port opening; 20" port depth; the woofer can handle up to 200 watts RMS (100 watts per voice coil)
* SPL/Deep Bass: 1.75 cu/ft; 2.5" x 10.5" port opening; 20" port depth; the woofer can handle up to 200 watts RMS (100 watts per voice coil)

How about this amp?
http://www.crutchfield.com/App/Produ...8ZX3001&tp=115
This box is to small I think.

Jma20a 06-26-2008 08:11 PM

that amp will work, your sub should be put into a type 2 enclosure according to crutchfield

4.0l sahara 06-26-2008 08:22 PM

Since I will have 2 amps i will also need to switch to 4ga wire right?

slf41002 06-26-2008 08:25 PM

I have a panasonic head unit with a ProFile CL 600 amp and a 12" MA audio su and Polk audio dash and sound bar speakers.

Jma20a 06-26-2008 08:27 PM

4ga should be ok. you might want to take a look at a duel amp wiring kit like these

Triple88a 06-26-2008 08:41 PM

I have a 12" kicker and i have enough space to fit both of my full steel doors back there. I love my kicker, it sounds amazing. I"ll post some pics later.

Jma20a 06-26-2008 08:44 PM

yes but you have a larger jeep than he and i do

4.0l sahara 06-26-2008 08:45 PM

could i just run a second 8ga wire? It would be cheaper.

603TJ 06-26-2008 09:02 PM

8ga is totally fine. buy a distribution block to spilt the power to the two amps, that's the way to do it. also can i just say one thing... What's with all the Crutchfield references?? everybody on the forum sh!ts on Quadratec all the time... don't you realize Crutchfield is the Quadratec of Car Audio!?!!!

4.0l sahara 06-26-2008 09:07 PM

i'm just using it for links. Yes there pricy but have good customer service.
I'm running 2 amps so 8ga i would think is to small.
