so if it said free no problem and about more batteries that depends on wish amp do u have
a t2500-1bdcp or
RE AUDIO XT V3 SERIES XT4000DE
good options but i will go with the rft2500 clean power and more power efficient the xt4000 good amp but always wants more And more power and the rf could make 3200rms
abttery needed? or just a stronger battery in the engine bay?
