Ive done a few installs and Ive seen this problem about 4 times, where the amplifer sends out DC to the subs and ends up burnin out the sub. Ive tried alll i can think of but heres my history.
1st It was a KICKER 650 amp with Kicker L7 subs -----changed the amp out to a Swiss Audio AmP, this was a much bigger amp and it sent even more DC voltage. -----then changed a Pioneer4800 headunit to the pioneer N3 (that didnt solve anything Then I decided to change out the subs (since those got burnt out) and added two L7's) still a problem so i left that project alone before i blew those too. Next car had the same KICKER 650 amp with an L5 sub ------the subs got burned out so i changed the amp to a Kenwood 1800W that kenwood jus wasnt working period, took it backk and got another one and this one is now sending DC if anyone has a solution please let me know ASAP. -------------------- |

BAD BAD BAD BAD BAD BAD BAD.... VOICE COILS IN SERIES!!! NOT PARALLEL!! and then you have the subs in parallel?? your OHMS ARE WAY TOOOOO LOW!!! 4 ohm voice coils or 2ohm??
run postive into first coil, negative from first coil to positive on second coil, and negative out on second coil.... and then run subs in parallel.... no wonder you are blowing subs.... you are clipping like crazy due to the low resistance...
