sorry OP.. don't mean to try and steal or poke my way into this thread.. but how do you have these wired? one amp to each coil? is it safe to do that? because those are REALLY cheap for that power!
They are strapped, two amps working together for each sub. One is the master and all settings on that amp are followed by the three slaves. I put my temp probe on them today after bumping for a while and they ranged from 103 to 104 degrees which is not bad at all for 1.50 ohm load between the two strapped, which equates to .75 per amp.
