do you have to have an amp to power 10 in. subs or can they just run off the headunit? thanks for any answers

They CAN be powered from the HU, but you will get much better results powering them with an amp.

ok... thanks. the reason im wondering is im planning to build a sub box in my shop class and i dont have an amp yet so i was wondering if i need to just wait and get an amp before the sub would work

yeah...you need to block some of the frequencies or the subs will see a full range signal= sound that sucks balls. Itgs probably gonna **** regardless on that low power but...

For the best results (and to put a new box to the best use), use an amp.

Actually, they can't. Unless the HU has a low pass cross over built, so you can make X channel(s) to have some sort of a # db slope. You'll blow a driver trying to play it at full range.

Not to mention, most subs now a days (especially the cheaper ones) are inefficient, with the most not even producing much sound until 100 or so watts.

geowick is right, they will work but will be being underpowered... you wont really hear them. i did this once and it was not even close to the output i was looking for, almost non-existant. what kind of subs are these?

Better get something designed for low power and with high efficiency....There are subs that will work with low power...
