Alpine Type R's wired to 1 ohm

Gabriel Bronze Member Username: Flossin Post Number: 22 Registered: Jun-11	Posted on Friday, August 26, 2011 - 03:27 GMT I have my DVC alpine type r's wired to 1 ohm...i'm reading that I had to use something called "jumper" cables otherwise it wouldn't use both coils? I used just regular speaker wire to wire the subs parallel to my amp. Is that alright?

You can use the same type of wire you use to wire the sub to the amp to perform the "jumper" connections. If you use only one coil the rated power of the sub is halved.

So it sounds like a single sub wired in parallel as far as loudness go.

Gabriel Bronze Member Username: Flossin Post Number: 26 Registered: Jun-11	Posted on Saturday, August 27, 2011 - 01:43 GMT ok well my amp has two positive and two negative terminals, so i just wired #1 sub positives to positive terminal a, and #2 sub positives to positive terminal b, etc. i was just makin sure because if I can get more power i'd love too >=)

As for the amp as long as each sub is connected to one positive and one negative on the amp you are ok.
