What do I need to consider when buying amp and sub

There is another thread talking about the JL sub which I did not want to hijack. Reading the thread made me think of things I should be considering before I purchase either the sub or amplifier.

1. What kind of output's, or bypasses, should I be looking for in an integrated amplifier?

2. What should I be looking for when I purchase a sub in regards to integration to my 2 channel system?

I like the JL sub and my local dealer sells them. The Amps I have been looking at are Musical Fidelity and McIntosh.

Thanks for your help.

The JL subs don't take speaker level inputs-line level only with balanced XLR and SE RCA.

This is helpful, but it creates more questions. What is a line level connection and what are xlr and se? Are those like options 2 or 3 above?

Velodyne subs have the high level speaker input. Run 2 sets of speaker wire from your amp. One to your mains and one set to the left and right speaker inputs on sub. It is high level so it isnt gonna pull power, just obtain the signal. You can still use the sub Xover to blend into your system.
I use the vel with Focal 918s and set it just enough to add punch on the low end. works nice . Hope this helps.

I am pretty sure that I am going to get a JL Audio sub. What should I be looking for on an amplifier?

If you are going JL, you'll need an integrated amp with either pre/line level-outs or tape out.
