Thoughts on cheap subs?

Decided i miss my old bass, so i wanna do something cheap. I don't need heart pounding bass, just enough to enjoy my rock and rap a little more. I just want a little bit of help choosing between a few of these.

Rockford Fosgate P2D415 - 15" Subwoofers - Sonic Electronix
15" Dual 4 ohm Punch Stage 2 Subwoofer



Power Handling:
  • Peak: 500 watts
  • RMS: 250 watts
Parabolic Triangular Geometry cone support system for reduced piston flex
30oz. double-stacked magnet assembly increases excursion capability
Compliant linear spider eliminates need for break-in period
2" anodized aluminum voice coil former stays up to 100° cooler
Reversible concealing ring hides mounting screws
Large roll surround allows for 20% greater linear excursion than standard surrounds
Stitched-in tinsel leads handle tons of power
Custom 10-AWG nickel plated push terminals
Venturi-effect cooling design
Frequency Response: 20-250 Hz
Sensitivity: 86 dB

Rockford sub, generally decent from what i've heard.

Cerwin-Vega Vega154 - 15" Subwoofers - Sonic Electronix
15 Dual 4 ohm Vega Series Subwoofer



Power Handling:
  • Peak: 400 watts
  • RMS: 200 watts
Mica filled polypropylene cone woofer
Red rubber surround
Bumped back plate with vented pole piece
Woven tinsel leads
2" Voice coil

Not sure on this, any experience with this brand?

PowerBass M-154D (m154d) - 15" Subwoofers - Sonic Electronix
15" Dual 4 ohm M Series Subwoofer



Power Handling:
  • Peak: 850 watts
  • RMS: 425 watts
4 Layer, non-pressed paper DDC (Dynamic Damping Coating) finish cone
Large roll santoprene surround
Massive motor structure for high power handling and maximum output
Black emissive coated backplate and pole piece dome shaped to maximize air flow from the vented pole piece
Chrome push terminals to guarantee optimal power transfer from the amplifier to the subwoofer
Rubber mounting gasket allows an airtight seal to eliminate bass robbing air leaks
BASV specially designed resign coated high temperature voice coils ensure accurate linear excursion and high power handling while maximizing thermal hear dissipation
220 oz Motor structure
Frequency response: 22-400 Hz
Sensitivity: 92 dB

Seems like a poor quality sub because it's made of paper, right?

15" Single 4 Ohm Frequency Series Subwoofer

Power Handling:


FLI Audio FF15-F2 (ff15f2) - 15" Subwoofers - Sonic Electronix
  • Peak: 1200 watts
  • RMS: 400 watts
  • Minimum input: 200 watts

2” Dual layer aluminium voice coil
52 Oz Ferrite magnet is 5-1/2" in diameter and 1" thick
Y25 Magnet rating

Big magnet, doesn't seem terrible but why such a big frequency range?

then there's always a deal like this

Plan would be to wire all setups for a 2 ohm load on some cheap amp.

i just got all of my stereo equipment out of my truck that the oxycontin girl totaled, and i now have 2 12" J L Audio w2 d2v2 subs, and a two month old amp for them that i am going to put into the GTP. i need to get a new box, as i take the GTP snowboarding. does anybody have a sideways sub setup in their car?
 


With that type of setup, you are going to loose a lot of your volume due to the way the sub is firing. Towards the trunk lid is the best.
 
i guess i should also double check my thought process for wiring this. I'm planning on leaving the stock head unit, and since voltage is what's important for an audio signal, shouldn't i be able to wire in parallel with the monsoon amp input? that way they're both drawing the same signal at the same voltage?

that's what i was thinking. i will just do one 12 and bridge the amp. i'll put the other 12 in my work truck. i like it!

zr1vette, you want the power for your amp that will be powering the subs to come straight from the battery, with an inline fuse close the battery.

Right, cause the monsoon amp would have insufficint size of wire to power another amp. So you will have to run wire from your battery to the trunk.
 


Nope i did mine with the bose amp so similar situation, and had no issues with noise. But remember it needs to be the amplifed signal otherwise it will make little to no noise at all.

Help me out with that. not catching what you mean.
 
Because the converter uses the signal from the amplifer to the speaker, not from the deck to amplifer. The signal has to be amplifed for the converter to work properly easy way to put it.
 


ohhh ok. i gotcha. I haven't ever looked, are the lines from the amps to the speakers RCA's? Is that link that I posted the right part?
 
cheapest price on that rockford i've found is 100 bucks from millionbuy.com. I've bought from them before and it went smoothly. Just gonna hold out a while and see if i can do better
