chopper groove
i finished my new stereobox a few days back. it’s virgin flight on a scul mission was mostly successful. it only took a while to figure out that the cause of the amps cutting out was due to poor wireless transmission. … so i hung the transmitter out of my bag, over my shoulder. it’s great now. i’m surprised that these new amps don’t need a heat sink since they’re much for powerful than the previous radiobox that did need a heat sink. i consider making the old radiobox (pic, another pic) was one of the best things i’ve ever done. … you just can’t be upset or unhappy while riding around on your bike with your tunes blaring causing people to randomly sing and dance in the street.
components:
- Pelican 1430 housing | bearproof
- mb quart nka 169 6″x9″ marine speakers | made to withstand sun and saltwater
- amphony 1550 50w wireless monoblock amplifiers | class T, efficient and precise
- two 12v lead acid batteries wired in-line for 24v for the amps plus one more 12v for the transmitter | heavier than your mom but should keep this stereo playing at high volume for days
- iriver h320 audio source | has an fm receiver built in so i can pick up skunk’s transmission on scul missions
to do:
- add ac input jack for internal charger
- try different audio absorption materials to tune resonance
- possibly replace lead acid batteries with li-ion. it’s really heavy.

That’s pretty damned cool. I was impressed with the… volume… of Saturday’s mission. I assume this will be equal or superior to what I heard then?
I love those pelican cases, too. I just bought one last month, the 1620, for a bunch of band gear. Makes my life *much* easier, plus I can stand on it.

the sound on the mission is “compromised” by a few things in the chain coming from skunks source. when i play it directly from my audio source, it’s more impressive. i need to work a little more on sealing some screwholes better, but it still has nice flat response at relatively high volume. come ride with me sometime.
