Help with JBL 600.1 amp!!

[mlinarz]

Anyone wired a JBL 600.1 amp to a single sub? Sub is a JL W3 12" D4. I've tried a hundred different configurations but still not working properly.

The only way I can get a decent level of bass, is with fader set almost all the way to the rear, loud buttom pushed on head unit, and gain and bass boast set at upper tolerance. Obviously, this is not an optimum way to listen to music, with front speakers faded almost completely out. The amp has front and rear speaker inputs, of course I've tried both ways.

I'm pushing 300w into the single sub, so should be loud as I can take it. I took it to a local installer, and he pulled the sub out of the box to insure that polarities were correctly hooked up, which they were.

You can get some Y adaptors to spilt your RCA cables so they are going to both sets of imputs. This will make it louder so you can turn the gain down somewhat.

I tried that already. Didn't seem to make much difference.

I'd wire the coils parallel so you're getting full power, just turn down your gain and boost before you turn it back on. Go real easy on the gain after it's wired at 2 ohms.
