If you put the subs in the wrong size box could damage them and make you system sound like crap. good luck! also when you wire up your system, dont just turn up the level on the amp to make it sound louder.. that is there pretty much so you have an adjustment to match the amps input to your stereos output of the rca cables.. amps have adjustments because not every radio puts out the same voltage, some are milivolts and some are up to 5 volts. so if you match it correctly you should have great sound and not worring about blowing your subs. also you have to match your subs to the right size enclosure.. i would go by the subs recomended enclosure and size, i.e. sealed, ported or bandpass.

JL audio, Robert Fosgate, Autotech, and Kicker are the brands I like. When you are looking at a sub you need to look at the size of the magnet, the RMS watts it can handle, and the size of the voice coil. A good size to start with is a 10" sub. It usually fits in most cars but still has the surface area to give you a great sound. Match your Sub RMS wattage to what your amplifier RMS wattage puts out. The core of your system will be your amp. Make sure you get a quality amplifier. The average for cost in a good quality amplifier is about a $1.00- $1.50 per watt. So if an amp has 300 watts max and 150 watts RMS it should cost in between $300-$500 dollars. Make sure you thick a power wire and a thick Negative wire. This is very important. To supply high power you need those thick wires so you supply your amp with what it needs to give you the wattage you paid for. The box you make or buy is also very important. Make sure you buy or build a box to the dimensions given by your subwoofers manufacture. This by itself can make or break the sound. Basically if you want a good system you have to pay for it. A cheap system sounds cheap. Good luck! YES! JL audio, Robert Fosgate, Autotech, and Kicker are the brands I like.
