How do I build my box bass, and how do I connect the amp?
I searched all over the web and I do not rule out a clear definition. Here are two questions I have decided that I will build my own box. For my setup, I'll be using two 12 inch subwoofers pioneer TS-W301R. For the amplifier, most likely to use the sony XM2002GTR. Here are links to both: Amp (2 channels) http://sm.crutchfield.com/S-C6a7vlifyGn/cgi-bin/ProdView.asp?search=XM+2002GTR&i=158XM2002 2 Subs (12-inch single voice coil, 4ohm) http://www. Crutchfield.com / S-RlNOWhRfCnM / cgi-bin / ProdView.asp? search = w301r + i = 130TSW301R Now here is the question. For my case, a simple design that will be rectangular prism. Should I separate the speakers by attack of a divider in the middle? Or, should I leave the open space? This obviously leads to another question. Should I save the two channels of amplifier, then run for the two years following, or should I connect each sub to its own channel? Thank you.
Run the subs in stereo. You could bridge the wired in series. BRIDGE TO NO SUBS in parallel. While submarines are receiving the same signal audio, do not need a splitter. Technically, in stereo, it is possible that the left and right speakers can get different signs and cancel each other out. In many cases there would be little or no cancellation, but it is definitely possible. There is no harm or benefit to put a divider in the box if both submarines receive the same signal. If will download the picture, I would make a single camera and the bridge amplifier to the speakers in series. If you have not purchased submarines, purchased the DVC in place. You can wire in series and parallel then to give a mono 4 ohm load. If you already have the subs, do not worry, the bridge 8 ohm output should be the same as the sum production of 4 Ohms stereo for around 400 watts according to your link. The difference in the output of 400 W vs 500 watts is very very small. Indeed, the box shape makes little to no difference. Standing waves is something that was thought to make a big difference in the 20s, but today they know that means almost nothing. Good catch on the subs, I saw that. Do not exceed the number of RMS on the subs. Indeed, prices of scandal. Definitely can beat them. The TSW307d4 would be ideal for amplifier you're looking at. which are about 400w rms. I know a guy with the 10 "version and they sound great. I expect the same out of 12 years. They run about $ 20 more what they were watching, but you can probably happens for the same price on the website annother.
