Amp question

jdisenberg · 02-07-2006, 01:42 PM

I am familiar with hook up subs using the RCA cables. I got a amp to run my front speakers and it has a high input, and I am not familiar with this... how do I hook this up? It is like a five wire harness.

What are you talking about? "I am familiar with hook up subs" <--what does that mean?

Try to use complete sentences and avoid typos, it's difficult to read and understand when you have to go over it several times.

Also, You don't give any details at all in your description of the problem. Is this like a trivia game where we have to guess what you have in order to help you? Try describing the amp in detail and posting specs or pics if possible. Also, what are you trying to hook the amp up to (computer, soundcard, headunit)?

Does your amp not take RCA's? What kind of an amp is it? Is it a car amp? What is a high input?

it should tell you want those wires are. You come off the your head unit speaker outputs into the high level inputes on the amp. It must be an old amp if it doesn't have RCA

It has RCA too, but under those it says low input, would that be ok? And the instructions do say what the wires are but I am not using an HU, I am using a mac min.

take pics of the amp and stuff man...post it and we will be able 2 help..if u dont have camera then u can try the "low thing"

jdisenberg · 02-07-2006, 06:38 PM

Yeah, sorry about the typos. I am not familiar with hooking up amps...

By the way, it is a memphis amp.

If your not familiar with hooking up amps, than I would recommend having it installed professionally. Installation alone shouldn't cost that much, but it could save you a lot of problems down the line. You could mess up your amp, alternator, and/or car battery if you don't know what your doing...

jdisenberg · 02-07-2006, 07:17 PM

I am going to have the power installed by the pro. But I am building the box and running my cable, actually installation will not be done by me, but I want to do as much as I can.... And it doesn' hurt to learn what this is.

to tell u the truth...i have never seen anything liek that

Those are "high inputs" they use speaker wire from your headunit to provide signal for the amp. You should use the RCA's if your headunit (carpc WILL) have RCA pre-amp outs.

Say you had a stock radio from 1980. You could splice in to your speaker wires. Then take that wire, hook up to amp in the "high input area".

I don't know anyone who uses them. Kinda pointless IMO.

haha, okay
High imputs, known as speaker elevel inputs, are using the speaker wire from the head unit. Low level is RCA, which uses the preamp RCA outputs from yoru headunit. You want to use RCA wiht your carputer though. definitely. What you do is you take a 1/8 stereo (3.5mm) to RCA adapter ($6 at Radio Shack) and go straight from your mac mini to the amp (easy way) or use an eq (hard way and obviously not the way you're going to do it).

And they're not pointless if you're using your stock HU and upgrading your amp, a HU without preamp outputs, or you're using multiple amps from your HU (one for speaker, one for subs). They're practical depending on your use. It gives you options.

Speaker-level input
Number and type of speaker-level inputs. Speaker inputs let you connect an amp to a receiver that lacks RCA preamp outputs.

For a carputer though, they're pointless

.

And any idiot can install an amp IMO. Wring the mac mini in your car is harder than wiring a car stereo. The hardest part was finding a way through the engine firewall to get to the battery. If you are afriad or need guidance, make firends with a guy who does stereos and he'll walk you through it.
