Quick dumb amp Q

[Marky]

Once upon a time I was sitting a diploma in electronic engineering... It appears I have forgotten most of it, haha

I have acquired one of them classic old sony 444w 4 channel amps, I want to use it on my speakers for the hell of it (already have sub and can;t stand for things in my garage to be unused)

My headunit is semi budgo spec and does not have a front pre-out, so I'm using a line converter thing to give the amp an RCA input

Am I best to a) run all four speakers in 2 bridged pairs as just "front" speakers

or b) split that RCA signal to give the amp a front and rear input/output and have 4 normal outputs to the speakers, the head unit still giving "front" to speakers and "rear" to sub as before (so I can still do HP and LP filters through it happily)

...I think I've answered my own question while typing it out

If I was doing it i'd choose option c) go down to supercheap and buy an equally povo spec HU with front, rear, and sub RCA outputs for 70 odd bucks.

If not c) then b) would be the next best thing.

I'd bet my bottom dollar you won't get a headunit with 3 x RCA outputs for less than $200, probably lucky to find one under $300 TBH.

How many speakers / sub are you wanting to run? The best arrangement would be 2 speakers of channels 1/2, and then bridge channels 3/4 for the sub.

So the headunit doesn't even have a single RCA output? That must be one very very very pov-spec headunit. I think even the cheapest ones I've ever seen have at least a single RCA for a rear / subwoofer output. If it does have that one RCA output, use that for the subwoofer

No no no

The head unit is half decent, bout $280ish? It's a Pioneer one with the bluetooths and things

It just only has a rear/sub RCA (because I didn't think to check for that), and I'm already using that for an existing sub & amp I have now. I just happen to have this 4 channel amp I'd also like to give a home

Is okay, I have already answered own question

I always found that searching through the Repco clearance section on the website was good for finding a decent HU at a discount price. Normally about half of retail.

But anyway, def go with separate channels for each.

I had the same amp about 12 years ago powering 2 6x9s and a sub. It got the job done.
