<p>Is anyone interested in building a sound system that fits in a milk crate? It doesn't have to be loud. I am trying to avoid riding with headphones. I can pay you in cash or buttons, bottle openers, magnets, mirrors, or baked goods, or a combination of those things. speakingmytruth @ gmail dot com or discuss here. Thanks!</p>

<p>I call upon the assembled wisdom of the BikeSound group for input. Personally, I don't know that Fab offers enough information to judge.<br/><br/>I might consider using one of these for Midnight Marauders rides. Something lightweight that could be carried through the rough terrain these rides often traverse would be ideal. A high amount of decibels would be neither warranted nor appropriate.</p>

<p>Since the May Critical Mass ride, I have been powering my sound system with an 18aH Shorai battery. It has generally seemed to work well. The battery weighs just a few pounds and the system sounds good. It tends to last between 40-90 minutes depending on the volume of the music. </p>

<p>Since the May Critical Mass ride, I have been powering my sound system with an 18aH Shorai battery. It has generally seemed to work well. The battery weighs just a few pounds and the system sounds good. It tends to last between 40-90 minutes depending on the volume of the music. </p>
<p>Sadly, after the September ride it appears the battery is not taking a charge.</p>
<p>I called up the company. They said using their batteries for this kind of application isn't advised. It seems likely I over-drained it and in so doing, caused damage. They said it shouldn't be drained below 12.6V and doing the math using my two amps totaling 860W at 75% volume, the battery should have lasted maybe 15 minutes.</p>
<p>Even though they said it wasn't covered by their warranty, they agreed to take it back and try to recover it using their sophisticated charging equipment. If it doesn't work, I am S.O.L.</p>
<p>If I were to get the battery back, I would have to mount a voltmeter to my bike and the party would definitely not last as long. I could run it in parallel with a 36aH battery (which weighs five pounds), but that's very expensive. The battery alone would cost in excess of $350.</p>
<p>Just thought all interested parties should be aware.</p>

<p>Hi everyone,</p>
<p> </p>
<p>I have two speakers and an amp I'm will to donate to a good home. These were on a previous bike stereo of mine, but I no longer have that bike and have built a new system on a new bike. I don't really feel like going through the hassle of selling them so they're free to whoever wants them. </p>
<p> </p>
<p>Speakers (2): Sony Xplod. 190W peak, 4 Ohm impedance, 5x9 in ovals. They don't have grills, so you'd have to make some. I used plastic window screen. I bought these new for about $80.</p>
<p> </p>
<p>Amp: Denon DCA-450. 12v 50W x 2, at 4 Ohm. Appears to be the same as this: <a href="http://magnitola.com/en/usiliteli/81299-denon-dca-450-2x-kanalnik.html">http://magnitola.com/en/usiliteli/81299-denon-dca-450-2x-kanalnik.html</a></p>
<p>I bought this used for about $45.</p>
<p> </p>
<p>Everything worked the last time I used them, but that was about 18 months ago. Today I notice that there is something rattling inside the amp, so I'm not positive. During the course of my using/abusing it, I had to open the amp up a lot and re-solder the heat sinks. Road vibration would cause the solders to the break which would cut power to the speakers.</p>
<p> </p>
<p>If you're interested respond by email or phone (630.207.5906).</p>

<p><em>---EDIT---</em></p>
<p>The best 800w amp I have found may or may not a be a digital amp it's rated Class FD which I assume means it's a push pull digital amp. But I don't really know. It seems to be efficient and I would totally go this route if it meant I could push the power I needed. </p>

<p>Power supply, again totally cannot make up my mind. In fact I am sorta at a loss how I would have both AC/DC power... All the inverters and supplies I have found don't seem to offer this option. Any thoughts?</p>

<p>And finally, how the hell am I going to fit all of this on the trailer? It's possible this is such a large setup that it would be unstable if I tried to modify the trailer design of the AOSOM. This may require me to build my own trailer but I have no metal working skills so I would have to outsource this. Anyone know of a good, and not busy as hell, metal worker?</p>
<p> </p>
