Iron Aces Mod -vs- Aftermarket Head Unit

Looking for advice or compare/contrast on the iron aces preamp mod -vs- aftermarket head unit.

I assume most, if not all, of the high volume distortion on Harleys is a function of the fact that there are no preamp outputs on the radio so any aftermarket amps are forced to amplify an already amped signal.

Is it worth it to drop the coin on an aftermarket head unit with all of the necessary purchases that go with it, or does the Iron Aces preamp mod sound just as good?

Going after market will definitely cost 2x as much as the iron cross mod... I spent almost 450$ for an Alpine 149bt and the hawg wired install kit...

Now I justified it because I wanted usb inputs and bluetooth and it was basically 220$ more than iron cross audio to upgrade to an aftermarket receiver.....

The Alpine 149bt is a great radio....

I'd go after market, you can always sell your OEM unit and make up a lot of the cost. Basically you'll probably end up spending close to the same amount but have a better sounding more versatile unit.

I agree... It took almost a month but mine sold with the 5.25" speakers for 325$

We use the Iron Cross mods for all our installs.
3v clean pre-amp out works great on everything but the RF amps...but we cant get any radio to sound right with the RF when using pre-amps.

Racer X,
I've got an RF 300 amp, four 6.25" RF speakers and HK head unit. I've never thought the sound to be of a very high quality, particularly weak on the base. It sounds like the head unit is my problem? Would the Alpine head unit make a noticeable difference?

No

we've tried that amp a couple of times, and have never been impressed.
Cant speak for the speakers.

We currently use alot of the ARC Audio K125.4 with alot of success with a wide variety of speakers.
6.5's will never give you booming base, but we get enough of s useable frequency response

So, its sounds like the amp is my problem (no pun intended)? Thanks for the letting me know about the lack of base. The four 6.25" speakers are mounted in the upper and lower fairings. What options do I have to get more base--after I change the amp?

Impossible to say without hearing your current system or knowing what you're expecting.
Most basic rule regarding speakers (all other things being equal)
larger speaker area = more air movement = more bass
We've have some pretty good results with J&M 7.25 and Biketronics 7.1
