hello ive got 2 12 inch X TYPE and i listen to hip hop and trance allot i like the low end bass i was wondering if this roumor i herd was true the X TYPE sub is a sound quality sub and its not made to handle low bass its ment for old rock and if i want the low end bass get R TYPES ive burnt a few X TYPES and would this be the reason? Ive got a rockford t2000 mono block amp and im looking for the low end bass i dont want to blow anymore subs any advice.

X Type are more than capable of playing low bass.

Need some more info to help you...

Are your X types dual 4's?
Are you running sealed or ported?
What is the size/tuning of your box?
Do you have a subsonic filter?
How are your gains/bass boosts set?

i have used both sealed and ported the ported is 1cbic feet and its a spl box the sealed box is a dual 12 bassworks box i burnt 1 voice quoial they are dual 4ohm subs i made them 2ohm the gain was set low like to the firt line and the subsonic filter setting was set a little higher i thought it wold help to get these in to a seald box but no still burn 1 sub in it the bass dettings in the front are pritty high but i dont notice any distortion or popping sounds it sounds good the levels on the deck are also below zero so im mind boggled are these subs made for sound quality or bass?

They are meant to provide SQ at very high levels, they should do low bass with no problem. If you're burning coils on X types going to R types will just result in you burning more coils.

I suspect you're clipping the hell out of that amp to burn voice coils on X types.

Firstly, how is the amp wired? You should have a bare minimum of 1/0 power and ground, grounded to a point on the frame, and the "big 3" underhood wiring upgrade.

Secondly, you can't set every bass setting to max and expect it to work properly. I'd set the deck to flat or close to it, maybe dial in some boost at the amp OR the deck, and then set your gains properly.

Next, I'm assuming you're using a prefab ported box... 1 cube is WAY too small. Build a proper box, the recommended ported box is 1.8 cubes per driver + port + driver displacement. I'd say go ported as you obviously like a lot of output. Tune the box low, and use a subsonic filter set fairly high (maybe 28 hz). Maybe try the recommended ported box first, it's tuned quite low and should be nice. If you have someone design you a box you may want to go even bigger if space allows.

If you are going sealed I'd also open the box up to 1.25 or bigger per driver... bigger will play lower but will be more apt to blow drivers.

im not sure what it sounds like to clip the amp ive herd allot of people talking bout it but what dose clipping sound like ive got 0/1 gadge comming from the battery to 2 power caps 1 is a 1.8 and the other is 1.0 ive got a 0/1 gadge going from the rockford fosgate t2000d to the chasis of the car and 4 gadge from the cap for the power ive got 2 amps thats why i have 2 caps 1 amp for the sub and 1 for the components ones the T20001bd 2000 Watt Class-bd Mono Amplifier ther other is a p4004 punch

Your car has a tach, you know that if you go over redline that bad things will happen to the engine. In a amp, that redline is the point of clipping. It is when the amplifier has no more clean power to give. It is now sending a distorted signal to the speaker. The speaker plays that distorted signal until one day it dies.

This is generally from having the wrong settings on the amp, the source unit, the wrong match of amp to subs and of course the wrong box. To me it looks like you have the wrong box for some good subs and need to learn how to use the system properly. If this was done at a store, head back in to see them and ask them what clipping is. Ask them to show you how to prevent it in your system or you will have this problem again.

With the subs you have, I would pour some effort into a proper custom box for them and let them deliver the performance that they were designed for, performance that a generic Bassworx box just cannot deliver.

Clipping sounds like distortion, because it is distortion of the original signal.

Sound is like a wave... picture a sine wave. Imagine that sine wave is your signal going into the amp. Clipping is when the amp can't reproduce the peaks and valleys of the wave because they are beyond it's limits. Instead of having a smooth wave the peaks and valleys are flattened out short of where they should be. That's what I think is happening... you have so much boost in your signal, and probably your gains on the amp very high, that the amp does not have the capability to reproduce the signal at the volume you want.

I think your problems are:

1) Improper box
2) Clipping due to deck/amp misset
3) Possibly amp is not getting enough current

so your telling me that this setup should do just fine if everything is right then the box was made for spl and the place i bought it from said that the difference between this and a coustom one was verry small f/x audio in edmonton but since i bought the sub and box i upgraded my amp so since this has been don i need to upgrade the box now

That system should make your nuts shake. I really think it's just tuning and maybe some minor tweaks like upgrading wiring here and there.

12g at least from amps to subs.
1/0 from cap to amp unless it is VERY short.
1/0 from frame of car to battery & engine block to battery & maybe 4g from alt to battery.

That shop that told you a prefab box was fine is foolish... maybe a prefab sealed box is not bad if it was a good one, but a prefab ported box for those subs is a joke.

ive got 12 gadge from the amp to the subs and 0/1 gadge to a splitter and 4 gadge to the caps and amps whitch is short and 0/1 gadge from the 2000 watt amp to ground ive got min dimmage next to none but i should still upgrade the ground wire from the battery and altinator the gain is set low but the subsonic filter is high the deck boosts are -10 or lower i have the deh p880 premieer deck and its set to 80 hz
