hi i have a 2004 impala that im trying to temporality hook up a line out converter to for my system (amp: alpine mrp m-500 sub:alpine type r) until i get some money together for my head unit


i thought i did everything right, ive dont systems before but never with a LOC. the problem im having is that my sub is hitting when i have my volume at 0 and when i turn it up it hits to about 25% and then cuts out after that.. any idea what could be causing this? its been driving me crazy having this system sitting in my trunk not hooked up

Hmm. That sounds pretty bizarre.

It sounds to me that your gain is too high and causing your amp to go into protection mode. If there is a separate gain on the LOC, try turning it down. If not, try turning the gain down on the amp. If neither of these solve it (and another member doesn't come up with a solution), I'd try a new LOC

Some models do, some don't. Another option is to see if your amplifier has "high level" or "speaker level" inputs. This is essentially an LOC built into the amp.

You wouldn't change any settings. Basically, you'd wire the leads that you spliced into the speaker wires into the high level input on the amp. No need for an LOC or RCAs

i just checked and it does have the speaker level inputs!

the only problem is is that how to you connect the wires to it? i looks like it needs a harness or something ? any idea?

There is a small harness that should have come with the amp. If you bought the amp second hand, or threw away your packaging, you might be SOL on the speaker level inputs
