I am planning on getting 2 Jl Audio 15" W3 subs. I am going to put them in my Z71. What amps should I get? What all do I need to run these subs? Thanks

Get a JBL 1200.1. My friend had his 15W3 running off a 600.1 and it was really loud. They are only rated at 400 watts but as long as your careful they will handle it all day.

I prefer the JL audio. Should I get 2 15" or 2 12" subs. What is the difference is performance?

If you wanna be super loud then get the 15's. I don't understand what you mean by wanting to stay with the JL. Get the 15W3's and push them with the 1200.1.

If you look at 1000 watt amps, make sure your alternator can take it. You will definately want to upgrade your battery regardless of the amplifier power.

Generally, 15's are louder and will hit deeper, 12's seem to hit good at mid subwoofer frequencies and give closer to a 10's punch feel. Keep in mind this is completely general, not all subs perform the same.

As for giving them a lot of power, JL's subs usually don't mind it, but I don't recommend going over their thermal handling. The safest power group to stay in would be a max of 600-800 rms.

There are many sub brands out there, even many that surpass JL. Don't limit yourself.

I do not know anything about systems. What does pushing them with the 1200.1 mean? The continuous power handling is 500 watts. What does 600-800 rms mean?

Pushing them with the 1200.1 means hooking the subs up to the amp to get them to make noise (the 1200.1 is the jbl 1200.1 amp). Since the subs are 500 watts continuous (500 watts RMS) then 600-800 rms means that you would be giving the subs inbetween 600 and 800 watts. but divide that number by 2 if you are running 2 subs. so each sub will recieve anywhere between 300 and 400 watts which should make them sound LOUD.

continous power handling is RMS, just worded different, if you can fit the 15" W3's then go with them. the JBL 1200.1 will give your subs 600rms a piece.. if you want to go all JL then get the JL 500/1 but it will be a bit costly but if you can afford it then do it.. i would recommed the JL 500/1 or the JBL 600.1 aside from the JBL 1200.1. do you have a Ex cab Z71 or a reg cab?

I am either getting a king cab or an extended cab. I cannot seem to find any of the JBL 1200.1 amps. Any tips?

I believe the jbl 1200.1 is a discontinued amp. Are u gonna be pickin up the 15 w3v2 or a 15 w3? i went to the jl audio website and they only had the 18 in the w3. try looking for an amp that is rated anywhere between 600-1000 watts at 1 ohm (provided u get the dual 4 ohm voice coil model). look into rockford fosgate. there are a lot of other good brands but im having a brain fart right now. happy hunting.
