After looking around, I've been thinking about adding two amps to my factory HU(Navi). My question is, both amps have speaker level inputs, but would it be OK to run both amps off of the same speaker wire (from the sub?)? Or will the signal be clipped all to hell?

I've decided to go cheap on this one. Instead of the RF-T15001bdcp, I'm considering two Kenwood KAC 9105d's for my subs.

Or would I be fine using speaker level inputs on amp 1 and then RCA preouts for amp2?

2 sub amps?

Drudis

yes

My 8105d has rca out but not sure it works with high level input. I imagine the 9105 has an out as well.

Does either amp have an output section? If so, run speaker to one and then output to the other.

Jda-yes it does, but I'm stuck wondering if that would be an ok signal, obviously I want both amps to have the exact same signal and gain level.

SteveMK- I'm not sure but I think it will work, just don't want to do that if it will be hard on one of the amps. Do you like the 8105d? I looked at those as well, but I wanted something bigger because I plan to upgrade my subs soon.

Yup I do. It works great for my application but that is just a single 10". No overheating or anything. Just consistent good sounding bass. Using the rca outs should not harm either amp. Give it a try. Shiuld be exact same signal being output to the other amp.

The signal should be close to the same level. The only time it would be crucial to have the exact same signal is if you plan on running one amp to each VC of the same sub which I doubt you're doing. You can easily check the output section with a meter to see if output is the same between the two. I've literally heard of people running their sub bass stereo with each channel going to one vc of the same sub.
