Whats up guys, I am looking for a stereo shop in NorCal that can help me upgrade my system... Right now I have Diamond Audio speakers on all 4 sides, 2 JL w1 and 2 Arc Audio Amps... Best Buy did the install and when they put in the Hi-Lo Converters, I still have to raise my amps all the way up to get any decent sound. If anyone can help, I would appreciate it

 

you mean the cross overs? they might have put it in wrong. why do you even need a hi low converter. just take the wires from the rear sub and convert it to RCA for your amps.
