2g radio help

[Boostnvegas]

Does anyone have the factory diagram for the wires for the 2g radios? My harness was hacked up by the previous guy. He just cut everything. It's a mess!! A wire diagram would be super helpful! Thanks in advance fellow DSMers!

Also I was reading on here if I have a factory amp I have to by-pass it? Is this true?

I don't know about bypassing the amp, but this thread has some good info.

Hope this helps.

Bypassing the factory amp is optional, depending on what you want for your speaker setup. If you're going for aftermarket speakers (usually 4 Ohm) and you have an amplified system (usually 2 Ohm) then you should bypass your factory amp. If you're fine with the stock speakers, then don't worry about it, just buy an amplifier interface plug, and a radio with at least 2 RCA outputs.

Otherwise, you're looking at finding the factory amp (under the passenger seat) and cutting the speaker wires off the plugs, and connecting your outputs from the radio to the outputs of the amp. Not hard, but not easy. It's a lot easier when you know what the speaker wire input/output colors are at the amp. You can test by using an Volt Ohm Meter to see which wire pairs have the proper resistance, (4 Ohm aftermarket, 2 Ohm factory), but if you're going to aftermarket speakers, then you 'll be able to check the speaker wire colors in the doors, and rear quarters...

Could you explain why you should bypass the amp? I have been running aftermarket speakers, (4 Ohm measured with DMM) for six months now, they haven't blown, and the amp doesn't overheat.

The primary reason you would bypass the factory amp is if you wanted to replace factory 2 ohm speakers, with 4 ohm speakers. Doing so would double the impedance on each channel of the amplifier, and thus cut the output of each channel by roughly half. So you would get significantly less volume out of your speakers. Running a higher impedance speaker shouldn't hurt the amp, it'll just decrease your available volume level. If your factory Infinity system had 4 ohm speakers, then there is no need to worry, nor a need to bypass the amp unless it goes bad.

Another reason to bypass the factory amp is for sound quality. Yes, Infinity is a good brand, and they make decent enough speakers and amps, but when you're looking at audio tech that's creeping on 15 years old, it might just be time for a little modernization...

Ahh good explanation. I am not really an audiophile, and I can turn the volume up past what is comfortable for me to drive with. For now I am happy, even though the setup I have now lacks base in a major way.

I will be rectifying that soon enough though.

In a 2G, you can get some pretty solid bass with just a little sub system. I ran an Alpine Type R 12, in a vented enclosure with an old Alpine 500W mono block... Big booms!
