Best Replacement Sub - PnP

[Rawyzf]

Hey Guys/Gals,

I just wanted to know what the best replacement sub would be for the MSP. It has to be pretty much Plug N Play as I don't know much about audio stuff.

I would like it to be pretty much a direct replacement, so I don't have to move anything around. Also, it has to be able to run on the stock amp as I don't want to replace that anytime soon.

I would also like it to be no higher than $100, if that's possible, but quality.

Thanks,
Ryan

I bought a RockFord Fosgate sub 8' Stage 2 for 60 bucks, Nice and tight on the lows. If you want pictures on how it fits and all i can post them up later if you want.

[Rawyzf]

That'd be cool if you could. I want to keep the stock look if possible.

Oh another thing the only thing when u upgrade the sub, your cover wont fit (mesh cover).

[Rawyzf]

Is that in the trunk, or visible from the inside?

It's in the trunk if you look where your sub is you will see a black mesh cover. It's nothing big though.

Cool

dude, go do yourself a favor :) that little 8 isn't worth the plastic enclosure they surround it in! nor is the amp for that matter... go get a real amp with some power and some 10's or 12's. It's all pretty plug n play... you shouldn't have to worry about anything to technical when installing bump bump!

Very informative thread on the subject.

I want to get the Rockford Fosgate sub as well.

i heard the JL w0 8 in. was PnP as well. That is what i was considering. You can pick them up for about 75 bucks. The only thing im unclear about is whether to get the 4 ohm or 8ohm. I have heard 4ohm works quite well, and sounds better but might max out the stock amp? Any answers?!

[AlexTheBum]

I haven't had any problems with my amp over heating, the sub i have is a 4ohm.

I went out and bought the rockford and I like it. I didn't really want another system they always seem to get stolen. Plus the lil 8" sounds pretty good for what it is imo.

[Rawyzf]

exactly what I was thinking.

So...what's the dif between 4 and 8 ohm?

What do we have stock?

We got 8ohm stock. 4ohm will hit harder because more current can pass so more power (watts) can be produce !!!

Yep, I went with the JL8w0. It hits hard, and unless you want to be deaf at 40 years old, you don't need anything bigger. I paid $79.99

Do you have the 4 or 8 ohm?

It runs at 4ohms. Simply take out the old one, put in the new one. I *believe* you have to switch the amp over to 4 ohms...but I can't remember. And as posted above, you will not be able to use the stock grille. Oh, and be aware that the dumbasses at the factory used loctite on the screws, so you may have to drill most or all of them out. BUT, you will be pleased with the improvement. My rearview mirror shakes like a mother now.

[Rawyzf]

Can anyone link me to where you can buy this for under $80. I keep seeing $99.99.

Well, if you get it from an unauthorized dealer, you won't get any warranty. I could never find one online, I got mine from Stereo One in Memphis for $79.99 back last spring.

[daedalus]

ditto couldnt find it online anywhere... i dont have one but the only one i have seen is at a local car audio shop.

I didn't switch it to 4 ohms? i dont remember seeing any switches on the amp. Can anyone clarify this?

[daedalus]

yea you dont need to. It just runs more power to the sub, and thus sounds better. Stock is 8ohm. No changes needed. just plug in the two wires and go.

[Rawyzf]

Cool...we'll I checked Best Buy and Circuit City and Ultimate Electronics last night, none of them have JL. I guess I'll have to find a specialty store for car audio.

[mspdfreak]

Yeah, JL is hard to find around here.

Everyone is talking about the Jl and RF speaker.. I happened to be walking through a local audio shop and found an audiobahn 8" sub. What do you audio guys think about the specs on this (since I'm not a audiophile I have no Idea what these specs mean). I've seen them on the internet for as low as $35 which I don't think is a good sign.

AW831T or AW831SE(this is supposed to be a special edition of the other)
8” NATURAL SOUND WOOFER
30 oz. Strontium Magnet
Power Handling: 200 watts RMS
Frequency Response: 30Hz - 1kHz
Efficiency: 90.3 dB
PHAT Foam Surround
Non-Pressed, Non-Transfer Paper Cone
KM3’ Coated for Virtually No Cone Distortion
1.5” 4-Layer ASV Voice Coil
Dual 4 Ohm
2 or 8Ohm Operation
Mounting Dimensions: Depth; 3 7/16”
Hole; 7” Diameter; 8 3/8”
MULT-CONNECT Lug Lock Terminals

Hmm...I don't think the stock amp will drive it at 2ohms, and at 8ohms, you'd still only getting the power of the stock sub. Plus, you may have fitment issues in the stock box. Plus, the JL is a proven winner.

[gen1pro]

It says it can run at dual 4 ohms... is that better / worse than 4 ohms

[mspdfreak]

I'm not sure, but I thought you couldn't run that amp at dual 4ohms.?

[Ex-Rolla]

don't bother with a dual 4 ohm or 2 ohm sub. The only reason that i would get any "dual" ohm sub is to have flexibility with the install if you have 2 or more subs...

Stick with the single voice coil and go with 4 ohm.

I'll give you an example why a dual voice coil (DVC) sub would be beneficial. We'll use a dual 4 ohm sub rated at 400rms. This sub, depending on how it's wired, can run at 8ohm or 2 ohm. Lets say you have a kenwood amp thats rated at 400rms @ 4ohm briged.

Using this sub, if you wire it at 2 ohm, you will be drawing way too much current from the amp, because it is not rated at 2 ohms possibly causing overheating/melting of the internal components. If you wire it up using the 8ohm configuration, you're not getting the full potential of the amp possibly only 100rms.

The only way you can use the full potential of this amp would be to get a single voice coil sub rated at 400rms. There are many alternatives, but this example would apply to the question above.

"it's really tough to explain the logic behind it"

Thanks that helped me understand it....I guess its back to searching for a RF or JL sub.

A friend of mine from work is going to sell me 2 JL 8W1's. I'm trying to get them for $120 (of course I only need one so if he sells them to me I'll be willing to sell the other for $60 plus shipping. I'll find out tomorrow and post what he says.
