Default Building my first LM1875 amp

hiii

i m building a LM1875 + PGA2311 with 3 input relay selection- confused for how to do hte pcb for 1875 , i have made a few layout could the gurus out here help me with it, hmmm only one thing is that i dont have schematics, all the designs are on datasheet diagrams also for the pga2311,

also if icould make one single pcb for 3 relays + PGA2311 + 1875 (2) than that would be just perfect , a small single sided 6"X4" or maby be a litter smaller so could probably do away will maximmum of the wiring
currently i just have pga2311 and relays on one board
