Line Leveler

I am not an electronics guy and confused about whether a line leveler is needed when adding an amp and speaker upgrade. I thought as long as I had the bike flashed a line leveler wasn't needed. Is this accurate.

These are the best bang for the buck.

Only viable options are BT355 or DSP with the LL being to most cost effective and simple solution.

Not sure what sled ur on but if ur on an ultra no flash is required as the rear channels already exist. If ur on a 2 speaker SG or RG adding rear speaks, u essentially need a flash that mirrors the ultra.

Clear as mud right??

Thanks for the replies. I don't really understand it all but I will be ordering the BT Line Levelers. From what i read, I think I need two, one for the front speakers and one for the rears. I have a 16 Road Glide Ultra.

Thanks for the help

Don't forget to inquire about the HD Forum Discount and also Military/Veteran discounts.
