I have a hifonics hfi1000.1d im trying to hook up 2 kickercomp cvr12 iwant to bridge them and run them in series

SOURCE: sub making horrible thumping garbage sounds

you need an noise filter in line. It's been a few years since I've had a system but I had the same problem. High power amps like the one you have can actually pick up on the electric pulses from your ignition system. I think I got mine at walmart, or auto zone, somewhere like that. Their pretty cheap too. I don't remember how its hooked up, but If you know how to hook and amp up, this should be no problem.

wire speakers in series google it to find diagrams

Most the time want happens is the postive wire is not the right gauge or the amp cant handle pusing two speakers you m have to put in two amps try hooking up one sub and see want happens if it dosent die out the amp not strong enough for the 2

SOURCE: can i hook up my sub if it's wired to a 2 ohm and my amp is 4 ohm

Hi martineztag
You should never connect a load of an impedance less than the min the amp is able to drive. This can have disastrous consequences that may easily result in failure of the amps output stages. You need to use a different configuration that does not overload the amp in this manner for safe operation.

wire the subs if thair dual 4 ohm . in parallel. red to red and black to black. giving it a 2ohm load. do the other sub the same. and conect it on the amp . turn your gain about 12oclock and db level less than 12oclock and your frequnecy around 80-100. and that should work
