cant help you with finding another viper. ebay is my marketplace. if you cant find it here or on ebay, you may be outta luck.
those solo's will most DEFINATLY get you a nice high spl. well, just make sure your setup is good. nice LARGE solid ported box...it MUST be VERY large. 0awg wire to the amp. a good ground. and tune your box right. solos slam like no other. your sure to make your mark at a comp with them @ 2500 or whatever you said.
im already there. thats why i bought myself 100sq ft of Fatmat. my truck is torn apart now in my garage. im throwing in the deadener and fixing my component setup. sound deadener is a MUST HAVE with systems this loud
oh yeah. im double layering my front doors and midpanels. and whatever i got left over is going in the hatch until i get more (if i need more, ill hafta see)
jesus! 3 cars? well, it all depends on what your doing and how well you want the sound deadened. if your completely doing a car (doors, trunk, floor, ceiling) 100sq. ft. should be plenty. if your double layering, you may need more. 3 cars?.....um....id say, buy 200sq ft (assuming your doing all 3 cars completely), and if you need more, just get more.
