Question about Sub Amp

Hey I just have one quick question about connecting an amp to a subwoofer. I just bought a sub and I am looking at an amp right now. The seller says the amp doesnt have a "crossover" so it wont work for my sub. Is this true? What is a crossover exactly? Can I get one really cheap and install it myself? Thanks!

It's just so much easier to buy an amp that has a crossover built in. A crossover cuts the frequencies that the sub shouldn't be seeing, out of the signal.

Also known as a High Pass\Low pass filter.

You can get them seporate, but in the interest of keeping things neat, it would probably be better to get it built into the amp, less wireing. Look around, you're not going to pay much more for an amp with a built in crossover.

What amp are you looking at currently?

What HU do you have ? Does it not have a low pass crossover on board ? Or to keep it simple, just provide us the model number (assuming it is aftermarket).

I noticed it says that it has Sub PreAmp Outputs... is that a crossover?
