thefordmccord Posted February 25, 2009 Report Share Posted February 25, 2009 What subs do you have? Two 15s? Two 18s? With two 15s in MOD3, you can run up to 164 amps of fusing. With two 18s, you can run up to 149 amps of fusing. You can spread that load across up to 3 smaller fuses. The fuses need to be within 18" of the amp.

sundownz Posted February 25, 2009 Report Share Posted February 25, 2009 You probably need in-line fuses within 18" of the amps.

thefordmccord Posted February 27, 2009 Report Share Posted February 27, 2009 You have to have a fues within 18" of the sub amp. That is the fuse that they use to determine what class you are in. If you do not have a fuse there, you will be put into a 5 class.

sundownz Posted February 27, 2009 Report Share Posted February 27, 2009 can you anwser the ? above about the termlaband i guess meca is about who has the best fuse lol My vehicle loses 0.1 dB MECA style - most vehicles lose more, it is not very common to gain. There are new rules on fusing to make it harder to just use "the best fuse" - I can burp four 3000Ds @ 16v on four 80-amp Sound Quest ANL fuses at hit 154.0 MECA styel.
