*Pics* Check My Settings // Bridging 4CH-2CH

[Kastlez_ 10+ year member]

This is my first time dealing with front stage and class a/b amplifiers so bare with me. Got everything yesterday but I had a couple more basic questions.

1) How to bridge this 4ch to 2channels

2) I have buzzing coming from the components (Tweeters, mids) on vol. 1 and up



3) Check these settings (Also I've only hooked up the RCA Output, Do i do anything with the 4 inputs?)

Thanks

Where it shows MONO and has a single + and -, just use those. Use the positive on the right and the negative on the left. Then flip the switch to 2ch.

The buzzing is just engine noise. Make sure your wiring is nice and clean and isolated from each other. Usually you get engine noise from a rats nest of wiring or bad RCAs or a bad deck.

Bridging makes senses thanks for that. I do have to clean up my wiring; I was eager to get everything powered up so its a mess.

Lots of people in.. anymore input?

I'm running everything passive and the front components are focal polyglass 165's would running the amp x-over on full vs HI be too much for these speakers so to speak.

Why do you have your X-overs set to high only? Is this an active setup and I missed that somewhere?

I would most definitely agree w/ galactic. More times then most though it's the RCA cables. But if not it's most definitely the wiring. Usualy ground wire to close to the RCA's etc.

Yeah i agree also like i said i through everything together, have to go and clean it all up next.

I'll switch the x-over to High. It's passive i'm assuming (I'm new to front stage as you can tell lol)

No, you already have them set to high. Since your running passive leave them at Full, your crossover will take care of the rest. yeah try out what you said and your problems will most likely go away.

Not all amps are the same, so OP, I'd suggest you read the owners' manual

I'm not sure about that one. If the signal is already HP'd from the HU then he can set it to Full, if not, the mids will be playing too low. Most crossovers only take care of the xover points between the mids and tweets.
