I'm SO Confused about the Stock amp. Please help?!?..plz?

[pjb84]

I dont mean to keep begging for help on here but I did some searching and could not get a clear answer on this...

I just replaced the stock cassette plyr in my 94 SHO with an aftermarket CD player...works fine.

But..now I want to add 6x9s into the rear deck in place of the stock 6x8s...can I just cut the harnesses of the stockers and wire in the new 6x9s?

Should I remove the stock amp?
What would be the benefit?

Im so lost here lol..again.

I have some guy on ebay who wants to buy my stock amp but Im not sure if I can take it out??:thankyou::thankyou:

With an aftermarket headunit you won't want the stock amps in there, the new headunit makes more power then the stock amp. As far as the wiring, you can just cut the connector off and wire the new speaker in.

OK thanks!! :woo-hoo:

Do I need to buy a bypass kit for the amp when I take it out? I heard something about this??

Be careful HOW you connected your new head unit. If you wired you stock/factory amp up via your new head unit's speakers cables you are going to create problems for both. You should only use the RCA pre amp outputs on your head unit. The speaker wires are sending an ampilfied signal to your amplifier -which it will not like - and therefore will cause perhaps both of them to eventually break (the term blown up is often used) plus you also run into ohm problems when mixing factory and aftermarket stuff togther. My suggestion is to use either ALL aftermarket or ALL stock/factory. And when I say all aftermarket I mean completely by passing the stock wiring for the speakers too. The factory wiring is sufficient for the factory equipment it was designed for, i will leave it there. When I actually start rebuilding my daily driver I am going to run proprietary wiring for an aftermarket system, this means separate power and grounding wires for amps and speakers and crossovers etc etc. And leave all the stock wiring in place and intact. This way I can switch back and forth without fuss or worry. But in all seriousness, unless you really know what you are doing I would not use factory amps with aftermarket equipment.

think about this...the stock tape deck sends a signal to the stock amp to amplify. now, that's all well and good, since that's how things are supposed to work. however, that signal's low power, letting the amplifier take the low power signal and...well, amplifying it. the problem comes when you send an already amplified signal and try to boost it even more, although the signal the amp's recieving is actually stronger than what the amp puts out. needless to say, distortion becomes an issue pretty quick. not to mention the aftermarket head unit's gonna give a lot cleaner and stronger sound than the early 90's factory equipment could dream of producing.

ok thanks so much. So I am removing the stock amp. Is there a thread on here about that? I will do another search here in a min if I dont hear back from Ya'll. Thanks again!

Why are you removing it? It is simple to access in the trunk. Simply unplug the wiring harness going in to it then undo the screws holding it in place. Bear in mind that to have your system work you will need to utilize that wiring assembly to get sound to your speakers unless you have bypassed it all together. But my suggestion is to leave the stock amp alone and in place, your gonna have to run your own speaker wires anyway, so leave it be. Whoever is trying to buy it hopefully has another SHO and is trying to restore a stock system. He should be able to find another from a parts car. If he doesnt have a SHO then why ever does he want that amp? Even Walmart sell cheap Jensen amps that will work just as well, will be clearly marked and easier to adapt to whatever head unit he has. Of course he may be offering a sum you cant turn down. My sugeestion would be to leave it alone. If you ever sell your SHO and all the factory wiring is intact and all parts still there it will be worth more.

...or he could just pick up an amp bypass kit, plug in into the harness in place of the amp, and make happy with good tunes. why overcomplicate things?

 

[pjb84]

where can i get this sacred bypass kit???

the guy has an sho looking to return to factory

 

[badcamelot]

He still has to connect his head unit wires to the bypass kit....you're right, it is extra work to run seperate wires but it is cleaner and in the long run less complicated, just more work. I've no doubt one can succeed with a bypass kit. Just offering a different way.

 

[badcamelot]

Crutchfield probably have one, but I would suggest a local car audio shop. They can probably give you a little guidence too and if something goes amiss you have a local source to work with.

amp bypass kits can be had just about anywhere that sells somewhat upmarket car audio...best buy and the like. as far as using one, you unplug the two plugs going into the amp and plug the into the corresponding plug on the 6" long harness...very, very hard to screw up, and takes about 45 seconds. i've been running one for years in my cars, including my old system which i used in competition more than once.
