Couple quick questions on sax100.4

[jcardin 2]

I just got my refurbed 100.4 and got 3 quick questions.

1. I have existing 8 gauge power and ground that connect to the primary battery less than 3feet from the amp. I would like to run this amplifier initially to power a subwoofer 4ohm off of chan 3/4 and leave chan 1/2 empty. Would this be ok? I would upgrade to 4 gauge when I hook up the front 2 chan.

2. I have a pair of RCA's from my sub out on my HU. Is this going to provide enough signal or does this amp require all 4 rca's to be hooked up. I think they should be ok, but just wanted to ask.

3. On the cross over pots, they are marked as 50hz to 500hz. Is it safe to assume that it if I placed the pot in the middle I'd get 225hz, and then If I placed in between the '250' and the 50 that I'd get 112 hz?

Thanks

John,

1) That is fine for such a short wire.

2) You do need to use input to all four RCAs - you can use Y splitters.

3) That will get you very close, yes.

Let me just make sure I was clear on number 2. If I was JUST running Chan3/4 for a sub and not using 1/2 would I still need the 4 rca's to be hooked up?

And would you still recommend going 4gauge when I do move to using all 4 chan?

And...Thank you for the quick reply.

In that case, no, you can use just CH 3+4 with RCAs only into CH 3+4 of the amp.

It wouldn't hurt to use 4 awg, but honestly, with just like 3 feet 8 awg is fine.

cool, thanks!
