i can't wire them different because they are single 4ohm voice coil and the amp isn't 1ohm mono stable. I play it 1 hour and it was cold like ice, it don't get even little hot. Is that normal.

the subs will be in 2ohms.

if you wire them how i showed you.

that amp is 2 ohm stable.

i just checked.

its fine if it doesnt get hot.

now they are wired like that:

one to the left channel and other to the right channel. The subs are single 4ohm voice coil each. And the amp isn't stable at 2ohm mono.

yes it is.

look.

http://www.ultimate-sounds.com/lanzar/la6.htm do you see 2 ohm stable, i do.

just wire them in 2ohms. you will have the most bass that way.

No i can't wire that because:

Amp is 2ohm STEREO that mean each channel is stable at 2ohm but in bridged mode with two 4ohm vc wired in parallel to get 2ohm, each channel will see 1ohm and the amp isn't stable at 1ohm. I'm 100% sure of that.

you either need an amp that it 2ohm mono stable. with same subs

2 more 4ohm subs. with same amp
