After market amp

Postby WINGRIDER345 » Sun Jul 27, 2014 7:51 pm

Has any one installed or had installed an after market amp to work with the stock radio? I have a 89 and replaced the stock speakers with aftermarket 8 ohm 250 watt. The stock amp just don't push them enough. :?:

I don't see why you can just find the feed out of the old amp splice in another amp in line, add separate power to the new amp and go??? Or find the OEM amp cut it out of the circuit and splice in the new one with a separate power supply.

This is off subject in regards to an addition amp but it saved me trying to fit one.

I have replaced all 4 speakers on my '88 with new 4 ohm speakers (3 ohm is standard) and to get them a bit louder I use a free program called Mp3Gain on my PC that increases the dB's of my mp3's before I use them on the bike via a cheap FM transmitter.

The larger the ohm number is, the quieter the volume will be until you get down to 3 ohms ( stock ), lower than that is hard on the radio. Car stereo speakers are designed to run at 4 ohms, most bikes too. . . .ours are kind of weird at 3 ohms. I would do a 4 ohm set, not AS loud as stock, but will be clearer sounding. That is my plan any way.

Reputation is what other people know about you. Honor is what you know about yourself. Our stress about it happens when the two aren't the same. Be true to yourself and to hell with what everyone else thinks!
