i who knows nothing, sub help

i got a 100 rms 200 max sub and a 400@4 ohm max amp. The sub requires an 8ohm load - how am i to wire this? the amo maxes at 4 ohms.

If you have 2 subs you are running a 4 ohm load already.

What kind of subwoofer is that? A singe voice coil 8ohm car audio driver is highly unusual.

Need more info. What kind of sub and amp do you have (brand, model, specs)?

it's a pioneer GM-X572 400 watt amp that puts out 200 watts @ 4 ohms, peak power at 400. the sub, is an older rockford fosgate 10'' punch that is 100 watt rms, 200 watt max and wants that 8 ohms of resistance. I'm not exactly strapped for cash, but this is clearly a money saving solution to my bass lacking problem.

oh yea, thanks for taking care of me.

The only way to wire that sub by itself to push the most watts you can into it is if you bridge across the amp. This will give you about 75 x 1 @ 8-ohms. If you have 2 subs, then you can bridge them both across the amp giving you 150 x 2 @ 4-ohms, into two subs which will be 75 watts to each sub, but you will get better bass, because you have two subs instead of one. If you have enough space, use a bandpass box cuz they give you more bass at the cost of lower bass frequencies. That won't matter since the old subs don't go down as low as the newer ones. Any more questions, just ask.

so i should just scrap this sub and get a little something newer. It's a small car so not a lot of bass is needed. I was considering getting a basslink just to simplify everything - whats the break down on those?

My personal suggestion for that amp and for a car needing little bass

Do that in a ported or sealed box

To tell you the truth, I wouldn't go with Audiobahn. I've had Audiobahn and they are completely over-rated. Their amps are sweet, but I wouldn't buy any of their subs. If you just want a little bass, the go with some MTX, Pioneer, Kenwood, a lower series of Rockford. I've also heard some Audio Art that sound pretty good and don't put out too much bass.

I would avoid pioneer and kenwood personally, Kenwood has awesome amps, but the subs I have heard of theirs really sucked. Pioneer is ok, but not a higher quality. I have had great experience from my audiobahn 15s they are fast loud and clean.

Well yeah, but 15's are totally different than 10's, as are 12's also. Since he wants only a little bit of bass, and he can prolly fit a bandpass box, then the Kenwood Excelons would do great, and so would Pioneer Premeirs. Pioneer had the subs that looked like they were diamond plated almost and they were excellent. The only reason I don't recommend Audiobahn is that I've had too many problems with speaker quality. They have great sound quality but the subs are built cheaply. You might even want to look into some Kicker, Infinity Reference or Perfects, maybe some JL's. JL gives you the best bang for your buck.

Os this what you are suggesting?

and this might be the kenwood? http://www.millionbuy.com/kenkfcxw1005.html

The pioneer is actually a good sub to go with for what he wants. A little bass and a sub that doesn't take too much to power it. You can wire the Pioneer itself to 2-ohms and if you get two then one per channel and you'll be pushing 150 watts to each sub which is plenty for each one. I know it says 250 RMS and 500 MAX, but with a bandpass box the bass will hit harder than normal, giving you the sound you desire. I mentioned the Kenwood as a quality sub, since you said that you wouldn't go with Kenwood because they suck. These Kenwood wouldn't go with the amp he has to push them, because they would suck the juice outta the amp and still want more, but those Pioneers don't take as much and will handle just fine.

remember this is not for me, lol

yo guy - that pioneer looks perfect for me. I'd have to get a different amp, but i'm not trippin on it. Here is my crazy idea for a box though:

since i'm driving a convertable there is a boot between the rear seat and the trunk for the roof to fold down into. The Rear seat comes down at an angle, so i thought i'd put the sub between the seat and the boot (which is enclosed) and then drill two three inch diameter holes in the rear seat and cover them with some kind of mesh cover that i'll fabricate later. It'll look something like this:







I thought it would be cool if the holes were right in the backs of my passengers (the car is 2+2) and it would make a nice natural box since it's small. On the flip side it's not very professional, but it also will save me lots of space.

Yo, if this is retarded, don't make fun.

I just must ask, what are the holes for? Is your sub going to be actually inside the boot, or will it just be outside on the front of the boot. If you fold the back seats down will you be able to see the sub, or will it be behind another wall, and the holes are just to allow the sound to come through?

I thought sub boxes needed an oriface to push air out of. I suppose it would be unessesary given that i only desire one sub and there is a lot of space back there.

To better explain myself: The back support of the rear seat is little more then maysonyte wrapped by a foam pad and some cloth. It creates an area of open space with the boot's retainer wall. the back seat does not fold down, but it is very easy to take off. I'm really strapped for room in this car so I'm looking for a way to have my sub, but not to put up with the wasted space.

you should be able to picture the amount of free space i have given the professionalism of my technical draft of the cross section of my car. Damn i'm good with photo shop. figure about 3 feet wide and 8inches deep at it's lowest point. I'd mount the sub at an angle to make room for the whole thing. This is just an idea i'm flirting with, what do you think.

Thanks for helping a brother out, I really appreciate it.

I'd go up to a pro at an audio shop and ask them how they would install that to take up the least space and ask for a cost to act like you are going to have them do it, then go do it yourself.

You can't make a box for cheaper, trust me

hey, you guys are great, thanks for dealing with me
