Subwoofer Questions ...

[loud92CB7]

I don't believe i contracted myself anywhere, if I have I will glady correct myself. All i was saying is that it is possible for a smaller sub to move as much air as a larger sub, and that two subs move more air then one; and when it comes to bass, the more air you can move the better, and to think ahead, and depending upon circumstances what you would like might not be what you can afford now, so leave room for improvements is what I was trying to say.

I bought my system right before I moved from washington because I knew it would help tremendously with the long drive from seattle, to houston, also since I was moving I needed sub & box that would occupy the least amount of trunk space.

maybe u just need to explain more on how to attempt these things.... i wanna attempt some if that its possible....u cant push as much air with 1 sub as with 2 but that requires doubling power to even come close.

8ohms is double the resistance of 4ohms and, 4ohms double the resistance of 2ohms, by reducing the resistance, you create more power, also your amp has to be able to support the resistance you are trying want to run. When wiring multiple subs and/or dual voice coils, you have several different resistances you can choose depending upon how you want to wire them. If you want a great reference information on how stereos, speakers, amps, & subs work, Crutchfield.com, has plenty of useful information.

more subs doesnt always = better/louder. i jl 13w7 would prolly beat harder then a lot of the setups on this site.

But, for the price you'd pay for a 13w, you could buy 2 other subs and probably a decent amp. And the newer JL woofers aren't really made for spl, they're more for sound quality. I've seen several new JL woofers come back due to the cone breaking/cracking.

I've got 2 JL 12w4's, the old school ones, it's insane, and doesn't weigh a ton either. Got em running off a Kicker Impulse 2252ix. Old school power ftw!!

no thanx ill pass on crutchfield..... have u actually competed or have mic experience? just because you wire to a lower load doesnt always mean your amp will make more power.

That is true, thats why i said your amp has to be able to run the resistance you wire up., or you'll end up most likely frying your amp.

No I have not competed nor do I plan on entering a competition ever. Not my thing, I love music, and I want to be able to hear every last detail, just as the artist intended. SPL or SQ designed & tuned competition audio systems do not provide me with the sound I desire. SPL leads to distortion, and SQ = great sound 3 blocks away, but like shit when your sitting in your car.

spl systems are designed to create the most pressure inside the cabin with as little distortion as possible. Distortion leads to heat, which leads to quicker blown subs.
A correctly designed sq system should sound great inside the car at normal listening volume.

A sq system does sound great at normal listen volume when tuned for normal listening volume, but I was referring to a competition very very very loud setup since he asked.

When it comes to SPL, its more of a bass competition, since its easy to create pressure in the cab with bass then using mids & tweets. SQ competition is like having a dance club sound system in your car. Well at least thats what it takes to win IMO.

For my current system I use 4x 6.5 Infinity References (shallows for the doors), with 45w RMS to each speaker @ 4ohm 12v. I then have 1x JL Audio 12w1 getting 300w RMS @ 4ohm. I plan on getting a second 12w1 in the future, and wiring for 2ohms which will be pushing 500w RMS 12v (Which the amp supports with no increase in THD).

what kinda sq are you talking about...... those are very narrow minded i might add.i wish u could have sitting session with my car right now... and then later when i add my subs. ill be doin both sq and spl but the spl ill do sumthing that takes malls and brains (bass race).

[sonikaccord]

You would be surprised how loud an sq system will get. It should be designed to be extremely musical and accurate at any dynamic level.

[acchonda]

Two subs definitely have the potential to be louder but just because you have two doesn't mean it will be louder.
If you are sending half the power to the two as you were sending to one they should sound about the same.
You have to look at what your amp can handle and how much power your alternator can put out. If your maxing them out before you make your sub happy then adding subs doesnt really help you.
