I recently had a 15" 1500w Technical Pro sub woofer that I powered with a Gemini-2000w sub woofer amplifier. Recently the sub has gone out and even though I know how to re-cone a speaker, it will definitely cost more to re-cone this speaker than the speaker is worth.
Instead, what I would like to do is to buy a 15" sub woofer and install it in the previous box. I host movie nights and enjoy recreating sound as it is in movie theaters.
Here is where my trouble really comes in... I would like to replace the blown sub with a car sub, which usually carries more power than a HT sub, but comes with the problems of not being able to hit lower frequencies outside of a pressurized cabin, such as a car. I have been told that it will not sound as good as a home theater sub in a home.
My first question is, WHY? How is the design different from a HT sub.
My second question, will i really be able to hear a difference between a 15" 2000w car sub compared to a 15" 1500w HT sub?
My final question leads into this final story. I have a acquaintance who let me try my HT amplifier on his car audio sub woofers. I am not entirely sure of the specs but do know his car amp is no more than 1000 watts. His subs can rattle my ears pretty good. When I tried my HT Gemini-2000w sub amp on those same speakers, the speakers acted as though they were not receiving enough power from my amp. The sounds were quiet and sounded terrible. ***I have messed with different variations of ohm amount. For example, I tried to bridge the speaker for more power but had the same poor sounding effect. Not sure what the ground/lift switch does.***
So, my third and final question is, why wouldn't my amp power his car subs? This all leads into me buying a car sub for a replacement to my blown sub. Am I going to have trouble using a car sub as a replacement for my HT sub woofer?
If you can think of any reasons my amp would not correctly power his car subs, please let me know. Also feel free to ask any questions that were not clarified clearly within the post.
Thank you all and have a Merry Christmas!

I think I know what you are saying itzdanielp. The HT sub was an 8 ohm sub-woofer while I believe the others were not less than 4 ohm speakers. I have an analog multimeter but when I try to measure the sub, I get no resistance or infinity ohms. I have tried measuring the resistance on a different speaker but still get infinity ohms. Not sure why, and I have the multimeter set to ohms 10 ohms. How would I tell if my amplifier only supports so many ohms?

I am not using a Low Pass Filter with my current setup. I have the signal from my main amp's sub woofer output plugged into the sub amp. Now, when you say stay away from 2 ohms, why is that? Isn't the less resistance the sub has, the louder it can perform at? I am trying to grasp the arts of the sound world but it can be difficult so please forgive me for any lame questions. Also thanks for the quick replies.

So, if I had an AMP that could support 2 ohm, then I could run 2, 4, and 8 ohm speakers with it?
Also, how do you measure the hz the AMP is generating and the speaker. As said before, I could not calculate the ohms my previous speaker supported for some reason.
Finally, do you think that this speaker, Lanzar MAXP154D Max Pro 15-Inch 2000-Watt Small-Enclosure Dual 4-Ohm Subwoofer, or something along those lines would work completely normal with my AMP?
Also, once again, will there be any major drop in sound performance using a speaker such as these?

Final question before closing the post. Firstly, thank you itzdanielp for all your help. As a college student at ITT Tech majoring in Electrical Engineering, it is always great to get a head start in some classes and helps to hear people clarify certain aspects of things we haven't learned yet. So once again, thank you for all your help
Now for my final questions, could my AMP burn out the previously described sub if wired incorrectly? For example, I wired the speaker to both stereo channels on my AMP instead of bridged the connection. Or if I wire the setup to hook both channels to the bridge on the AMP? Do I need to worry about burning this speaker out with the current AMP I posses?
Will sound quality be reduced being used as a HT sub? (The sub is 15")
And Finally, how loud do you think this speaker will sound in a home environment?
