low volume delco radio

i dont think there really is a sure fire way to tell if that radio is only made to run a factory amplified setup unless you know the exact car that it came out of. if it came out of a car with a factory amplifier then it is only setup to output a low voltage signal that sends info to a factory amplifier which then drives the speakers. if it came out of an 03 chevy pickup it might not say "Bose" on the radio itself but it would say Bose on the speaker grill on each door panel.

If you turn the volume all the way up, and the sound is barely audible, chances are it is a monsoon deck.

i dont know if you are using "monsoon" as a blanket word for chevy's amplified systems but monsoon is typically only in pontiacs. and monsoon decks usually have a 7 band eq built right onto the front of the deck.

I would estimate the sound to be about 25% of normal.

there is no eq on the unit

i think you just have a typical radio out of a truck with a bose system. they may be semi compatible because it will turn on with the vehicle's data signal, but it is meant to send a low level signal to a factory amplifier instead of driving the speakers by itself with a high level signal.

had similar problem, just take speaker leads and solder male RCA's and feed a small budget 4ch amp. I did the same for my brother, i had an old school jensen amp laying around. worked great if you want to go that route.Go BIG or go Home                                    it might not be broke, but lets fix it anyway

thanks

do you have any idea what the voltage should be for amp. systems and no-amp. systems?

voltage for amp, sorry i dont understand your question. the speaker outputs on delco/delphi deck are just right and you dont need a line level converter. just solder RCA male ends or female ends to speaker outputs of stock deck. i installed it in a reg cab chevy truck and kept factory speakers powered off the jensen amp. worked great. i never thought factory delco speakers could sound that good. the delco/delphi radio was out of my 04 crewcab with bose, i found out the same way about low level output as you did. cost was kept low by, low budget 8ga amp kit, some scrap RCA's, and some speaker wire. you should be able to pick up a sony 4 ch or cheaper brand amp @ wally-world, and amp kit...Go BIG or go Home                                    it might not be broke, but lets fix it anyway
