Bran - Those JBL speakers are 2ohm...not 3. The PEAK at 180w but are 60w RMS. (

When sizing speakers/amps/HU....always...always go by RMS not Peak. You want room for your speakers to get more power before the peak.
The nice thing about active subs is that they are an all in 1 solution. Sub, amp & box. Usually a downfire but they do have them in a ported setup. This is also a downsize as they are a Jack of all and Master of none. They really are the only solution to use in these cars unless you use the door panel & the Bose rear tray.
One other thing is to try and not use the line level outputs from a HU into an amp unless there are no other options. RCA will always be better quality & better voltage. Also watch the pre-amp output voltage. Some 1 din units only do 2v out vs 4v. Again, you want to match what you are hooking up to.
Everything will work if you mismatch things like speaker Ohm, pre-amp output voltage, etc....it just wont sound as good compared when things are matched correctly. And you do run the risk of 1 thing over loading another.
Not matching Ohm's is the biggest mistake people make. And you CAN blow your speakers or amp if you dont. Ask any electrical engineer or audio guy and they will tell you the same thing. Yes it can work...but for how long is the answer you will get. It's simple Ohm's law.
