Is running a pair of subs without an amp a good or bad idea. Will anything happen running subs with no amp?

Im no expert..but i dont think u can actually run a sub without an amp connected to it...there just isn't enough juice to properly power the coils..

So,,, because I just put my 2 12in subs in my truck, and I decided not to install my amp because there will be no room. So is running 2 subs without an amplifer good or bad? Or will anything happen?

yes it is bad. Subs are meant to be run in a low pass frequency's only. By running them on a full range scale you will fry your voice coils. Not to mention it will sound like doo doo.

Nah man, I run my subs without any amp. Superb sound quality. I just have to buy a new hampster every so often to spin the wheel and CREATE ENERGY.

Let me see here, so I heard that it is ok to run subs with no amp, but then I have heard that it is bad? Which one is it, and why.
You can't run a sub strictly off of RCAs. You can run one off of one of the channels of an HU (Or bridge the rear two channels, if that's even possible with an HU) Otherwise you need an amp.
You shouldn't run subs off the HU alone cause the power's too low. It's only 20W rms the most. Average subs are 100W rms or higher. You'd have to supply at least 50w rms for 100w subs to sound decent. Now for 300w - 1000w subs, 20w rms is not even enough to meet the minimum power requirements. Why don't you have space for an amp? If you have enough for sub, then you do have some for an amp. It doesn't always have to be mounted on the back seat nor trunk floor. If it's small enough, you can screw it on the side of the sub box (it should be your last choice).

Aight coo, so check this out, I have and extended cab toyota, and in the cab I have 2 6x9 hooked up, I took them out and hooked up my 2 12in subs. So no that is not a good idea to do that. The reason I dont want to hook up my amp is because it is way too big, wont fit under the seat and on the box maybe.
you can run Subs withour an amp but it will not go to the peak power volume max of the Sub if you have a good Sub. But you can this if you cant buy an amp.

Yeah I just read about that it is not a good idea to run subs without an amp, you could mess them up, so I'm gonna have to hook up my cheap amp to the system. I'm gonna check out that MTX amp. Any one else know a good cheap high powerful amp?
There are very, very few subwoofers that could hit respectable volume levels when powered off a head unit. Because of this, it makes you want to turn the volume up. When doing that, you'll end up clipping the head unit, risking damage to it and the subwoofer. Just not a good idea.
