Pre-amps? No way. Spend on buying good 2nd hand speakers and stuff. Alpine Type-S or Type-R speakers (they cost around 300 to 400 bucks 2nd hand). I've no experience with the amps so I can't comment. As for woofer matching and amps.. you need to look at the ratings. For example : Mohawk Orange 12" is 200 Watts RMS at 4ohms. So look at your amp. Does it have mono output? How to tell? Look at the ratings. For example : JL 300/2 2 channel amplifierRated Power (2 Channel Mode): 150 W RMS x 2 @ 1.5 ohm Rated Power (Bridged Mono): 300 W RMS x 1 @ 4 ohm This means the JL amp is 150watts RMS at 1.5 ohms for stereo 2 channel. Since Subwoofers are mono, you'll want to look at the bridged mono ratings which is 300 watts RMS at 4ohms.That basically means this amplifier will feed 300 watts of power into a the Mohawk Orange since they are both 4ohms only. Always look at RMS, not max power or whatever. That's what we call "sub + amp matching". Subs have 2 types, SVC (Single voice coil) and DVC (dual voice coil). SVC subs have one + and one - for the wiring connection. DVC has two + and two -. If the specs says it's a SVC 4ohm 500watts RMS sub, that means you need to find an amp that'll power at least 500 watts at 4ohms to get decent bass from the sub.If the specs says it's a DVC 4ohm 500 watts RMS sub, it very likely means each coil is 4ohm and since it's DVC (if you remember your physics), that means you'll need to find a 2ohm or 8ohm amp with at least 500 watts to power the sub. If it's a DVC 2ohm sub, then you'll need to find a 1ohm or 4ohm amp to power the sub.Quite simple. So basically, Mohawk Orange is DVC 4ohm 200 watts, means it runs at 2ohm or 8 ohms only. Your amp has to be 2ohm 200 watts or 8 ohms 200 watts to get any decent bass from the sub.</blockquote>
