that is not a too big of a dream! car audio now days are very cheap, cheap like dirt, compare when i got all the gears for high price back in 2003 , my alpine 65x4rms amp costed me like $800

i can get a kicker 6.5 inch component set for $75
a nicer kicker one i have is only $150 (with a 1" tweet)
2 channel amp MB quart 125w x 2 rms, $150

if you make a kick, , is it easy to make another copy ? ship it to me, i will pay you some.

another concern is, what power the extra set of front components? have to run it on 2 ohm at the amp?

how to wire them,
