I am a novice and I have heard it discussed about "tuning" to 30-35 htz. How is this accomplished?

$ 100.00 shipping included!!! I would say it is worth it. If I do the Big 3 would it effect output? After looking at whats out there now...I am wondering if I should sell this stuff after getting the amp rebuilt and get a new set up.

I have two U.S. Amps that I have had for years and I am wanting to get the specs on them. I had them installed in another vehicle that I recently sold and I am reinstalling them in another vehicle. Before I sold my other car the 150 fried which sucks, but another reason I am wanting the specs is to find out if it would be worth fixing. The first amp is a US 150 the other is a US 25.

I could go several different ways. My current speakers are (2) Volcano CDS 12's DVC 4 ohm and Dual Spider: fs qms vas qes re power rms 34 9.1 2.7 .45 3.6 400 watts I could purchase (3) Volcano C 12's SVC 4 Ohm: fs qms vas qes re power rms 34 9.1 2.7 .45 3.6 400 watts and a possible purchase would be either (2) or (3) Napalms: fs qms vas qes re power rms 34 7.36 2.6 .45 4 1000watts This is from the Manufacture email regarding the possible purchase of the 12c's or napalms: "I would recommend either in 2 cu ft tuned to 30-35hz. you could be a litter smaller with the Napalm. it has considerable more mms than the 12c" I told the manufacture when I was on the phone with them that I was going to put my current speakers in a 16"x35"x16" sealed box and he said to build that box and I started to try to get suggestions for something else and he said that was a perfect box. I have 16" top to bottom and 35" side to side clearance. That would get you to the very back of the back seats. Any help is appreciated.

specs for the speakers are. fs qms vas qes re power rms 12c 34 9.1 2.7 .45 3.6 300 watts napalm 12 34 7.36 2.6 .45 4 1000watts I can get the 12c for SUPER Cheap because they are discontinued. Napalm are DVC 12c are SVC. What would you recommend. 3 12c or 2 or 3 of the Napalms. Again it would be in a 2000 Honda Civic and I would like to keep the back seats.

So, the 150 would be worth a rebuild?? And the salesman wasn't lying when he stated that it could push out close to 1,000 watts. I am starting to get back in to systems again. The amp would be pushing 2 Volcano CDS they are 400 watts RMs 800 watts Max. This will only be a temporary system until I upgrade. I am contemplating on going with 2 or 3 Napalms. I have been corresponding with the manufactures of my old volcanos (which they do not manufacture anymore). He told me of a few new lines they are coming out with. The Napalms he said are 1000 watts RMS. He is supposed to be sending me the specs on them. The system will be going in a 2000 Honda Civic. Thanks for the help.
