Boss Audio R3400D setting gain level

[sta]

I have a Boss Audio R3400D and I have it hooked in parallel to two 4ohm subwoofers. What should I set the gain to?

Before we go into this do you understand that amp only makes a few hundred watts?

actually those make some power bro, i used one. probably 900w

To the OP; search "gain setting tutorial"

I highly doubt that it makes 900watts at most 500 with 14v and will probably fry in a month

its cheap.. however I have had it for 3 months now and it works just fine.

900 * 2 sqrt = 42v, is this what i should set it to?

I wouldn't set it any higher than 400 watts. You really need a I scope to set amps like this.

No lie, I cracked my mono "3000w" boss amp to like 70-80% an the 2chan "2000w" was set at like 50%. My highs wud cut out after 30mins, the sub never even got warm. I had it for about a year, got rid of the whole truck. System still worked....

If you have 2 d4 subs wired parallel you are at 1 ohm which equates to no more than 30v ac.

You can't wire 2 d4's to 2 ohms

I was so sure it was 2ohm.. it's Kicker Comp

Can't be done, period. If they are d2's and wired series/parallel you would have a 2 ohm load.

they r single 4s **** it. any one else want to tell him his single 4ohm subs can't be wired to 2 ohm. he needs to know how to set the gain not what he's wired to.
