building portable stereo for events.. ?

[brian84corvette 10+ year member]

hello. !

im planning on building a portable stereo from car audio equipment

to bring with me to gatherings like barbeques outside in the park

where electrical outlets are not avalable.

i have a fiew diffrent lower end amps laying around my garage I can use

to power the speakers,

and I even have a optima yellow top in new ish condition to use with it.

I was thinking I can use an adapter from a mp3 player plug that has rca outputs on it to give the amp signal, - that way ipod connects directly to the amp eliminating the need for a head unit.

I had planed on building a sub cabnet with seperate side boxes mounted to it to hold the 6by9's and mounting the amp and battery in this setup somehow with a hinged door to recharge the battery, and putting wheels on this contraption and a tow rope so I can just roll it along instead of having to carry it. maby some bigger off road type tires from a ? ( radio flyer waggon or something like it. ) - actually maby a kids toy waggon will make a great platform to build off of..... ? ill have to search one out.

any ways my question for you guys is this,

powering a pair of 6by9's and a small ish sub maby a 10"

how long do you think my optima yellow top will play at good levels of sound

before needing recharge? and how many times do you think it will

take charge/discharge before the battery starts going bad on me?

and powering off just the one yellow top - what do you think I can use for sound, like only 1 pair of components and 1 small rms sub ?

or do you think I could use 2 pair of components?

id like the system to play for about 3 hours or so before dying out and needing recharge.

please add your imput.

It would realley be sweet to show up at the park bbq and have good jams for every one to groove to.

If youre doing this...I would even experiment with solar panels attatched to the battery to recharge it slightly as you go and give you some more playing time...Ive seen people doing this with a rolling cooler at the beach..

They had the cooler, inside was a battery...they cut a hole for a basic 10" sub and mounted it using the cooler as the enclosure (mounted on the back face of the cooler)...then I guess had weather sealing around the edges of the lid to seal it up when its closed...then they made something that was mounted ontop of it that held a pair of 6.5" coaxials and a headunit...it also had 2 solar panels, one on each side of the cool tilted upward, but folded back flat against the sides when transporting it....

It was kinda funny/ghetto but would be pretty handy for some good music on the beach/lake/wherever

awesome idea with the cooler. I have seen a fiew that had back wheels and a handle on them too.

as of right now I currently have,

1 - optima yellow top

1 - rf punch 150w 2ch amp to power the highs

a pair of 6 by 9's and 2 cheezy spx 10" subs 50w rms each.

I wish I had a 4 channel amp to use like a kicker 350w by 4ch

so I could use channel 1 and 2 on the highs

and set channel 3 and 4 on lpf for the subs.
