Default 97-98 Old School Amplifier

Ok I couldn't resist getting this amplifier (Precision Power PC2100) when I heard my buddy wanted to sell it for $20...only problem is that it's so old school...I have no idea what to do with it...this thing is massive long...and I believe the specs on it is

25 WRMS x 2 @ 4W per channel
50 WRMS x 2 @ 2W per channel
100 WRMS x 1 @ 4W bridged

Although I'm seeing

2 x 100 @ 4 ohms
2 x 200 @ 2 ohms
1 x 400 @ 4 ohms bridged.

Around on google...so I don't know which specs is correct...although my interior speakers are well made for both specs...I would just like to know. Also what gauge wiring would work for this amplifier...yes I'm getting cheap on it sense it's only going to my back 6x9s...so nothing expensive...I just need a gauge size..last time I had an 8 gauge......I decided to use it for speaker wire...*I'm an idiot, I know* Some pictures of the amp is listed below, I know the amp is scratched up..I haven't hooked it up yet nor have I paid for it..my friend said he'll wait til I get the wiring...I'm hoping 8 gauge would be alright for this amp.

Old school? 1985 would be old-school.

8g with a 40 amp fuse should be good enough.

Those are nice amps, came in after the art series of PPI amps you need to find the plugs that connect the power and the speaker wires to the amp (a weak point in the PPI designs in my opinion) but if you can find those that would be a great buy.

Here is a link to the manual for your reference - http://www.directeddealers.com/manua...1997-1998).pdf

Nice amp for not a whole lot of money even when you add in buying the plugs IMHO.

I got the plugs xD unfornately it cost me $10 a piece =( But hopefully it will move my 6x9s. Lol @ perry...that'd be before I was born...if I owned a piece from that year...I wouldn't play it...it'd be like a plaque on my wall xD

I like those amps. I've had a PC450, PC275, PC2150, and a PC1400 all of that same series. I've never had one of the chrome versions which are also good. This and I believe the Chrome series were the last made in the USA amps PPI produced. They sound really good for what they were. I am not sure, but if the PC2100 does not have a fan then watch it's temperature if running more than one sub. It should be great for interior speakers.

Oh, and its 12v ratings are:

100x2 RMS @ 4 ohms
200x2 RMS @ 2 ohms
400x1 RMS @ 4 ohms bridged
Dont go lower

The manual claims input sensitivity is 150mv to 4 volts of low level input (RCA) or 4v to 12v if using high-level/speaker input.

Use the -12DB button for input up to 12v as if using speaker level inputs.

For 'normal' use you probably leave the -12db turned off with RCAs running directly from a head unit. The amp can accept up to 4v like this.


From my experience however, these amps will do extrodinarily well with just about any input voltage.
