Signal wire from amps...... Not sure

[saskyrider]

Hey all just about done with my system upgrade which consisting of a harpoon amp to run my new 4 sxt65's and a new amp rack and head unit. I am wondering if I can connect the signal wires from the amps together and just run one wire to the head unit?

Thanks Geoff

Yep, 2 amps should be no problem off a single remote turn-on. Good luck with the upgrade and of course post up some pics!

I am running 3 amps total. Will it still be ok?

Should not be a problem

Using a relay for 3 amps would probably be better, but I'm not sure the real issue. I tapped into the switched power wire that feeds the headunit instead of using the remove turn-on wire from the headunit.

Guys-

Proper sequence of powering on and off is important. Picture this: your amps are already on and you power up your head unit. The head unit often will send nasty stuf out the RCA cables while powering up. With the amps on, you can anf often will get noise or a big nasty pop.

Same thing when turning things off. Say you turn off your head unit while the amps are still on. Nasty pop again...

Using the blue, or blue/white turn-on lead introduces the proper timing circuitry and muting circuitry in order to prevent turn-on and turn-off pops. The radio's remote turn-on lead is delayed slightly to allow the radio to fully power up prior to turning on the amps. Similarly, when powering the head unit down, the remote lead is immediastely turned off, and the radio waits a while...

Some folks will have okay luck wiring the amp turn-on leads like Brain-Rinse but others will have a problem with blown tweeters.... It will always be preferred to use the head unit's turn on lead to ensure stuff is truly turned on and off in the proper order.

I have 3 amps wired to mine. No problems.
