Amp Upgrade Help Please

The Memphis 1000D is a phenomonal (did i spell that right?) amp. I have installed Memphis Class D and Class AB amps many time (the 3004 is a class AB amp) and they perform quite well. The 1000D will put out about 1200 watts on a 1ohm load...

Currently, my wife has a 1000D on her 2 12L7s in her 2000 mustang. It's a pretty sleak looking install if I don't mind saying myself... She also runs a 3004 on her mids and highs which are also Memphis (Memphis Studio series, aka Encore series... VERY clean). I've done the 1000D on many sets of Solobaric 12s and each time, the customers have been pleased.

Personally, in my system, I have one 10L7 in a downfire box that I designed in my 95 F-150 Xcab. I am running a Kicker DX700 on it... bridge at 2ohms. My surround is done by an old Kicker ZX460.

I have heard alot of good things about the JL amps. I too think the two Tarantula is overrated and overpriced... I heard the same about the DaVinci. I think you should save your cash and go with a JL amp or Kicker or Memphis. They are all tried and have been proven worthy by those of us who have installed them. Don't think you can go wrong. For 2 12L7's you would want to do something about 1200watts to both... they are awesome speakers and can handle lots of power.

Are building a ported/vented box or sealed? Reason for asking is that you can get away with less power if the box is vented, which could save you some money. Sealed boxes usually use more power to produce a certain output (and the smaller the box, the more power is needed and the higher the resonant frequency is). The vented enclosure is usually louder by design so you can by with a smaller amp to produce the given output you are desiring.

Hope this helps. If you want some ideas on some box designs, pm me with your vehicle year model and type and I'll see if I have something in my "cookbook" for one I've built in the past.
