I have a Original Soundstream Lil Wonder 4 Channel amplifier just rebuilt by Soundstream I would like to trade for a decent Head unit . Pioneer my first choice . Must have hp lp x-overs and atleast 2 pair of Rca out . Will consider other head units . The lil wonder is one of the best sounding amps I have ever heard and puts out good/clean "true" power .
