I have done a search and am confused I put a biktronics retroradio in mt 07 standard and it has I beleave has 4 ohm???? what amp and speaker upgrade can be put with this set up or will any one of the jm or hog tune ones work I am looking for a plug and play unit thanks in advance for any >>

 

I think the J&M and Hogtune speakers are 2 ohm. Any aftermarket 5.25" 4 ohm speakers will work with your setup. I have the retro radio in my 07 standard also. Im using a Sony head unit with Memphis Audio speakers.

 

Contact the amp vendors and ask them about your application. The amp will typically use the speaker outputs from your radio for its input signal and you'll need speakers that are compatible with the amp's output impedance. The amp's specs will tell you what impedance speakers to use; some are stable at 2 ohm and will also use 4 ohm impedance speakers. But, ask the amp vendors for their recommendations.

 

I have the same kit installed. Blew out the Hogtunes speakers and replaced with a set of regular Kenwood 3-way car (4-ohm) speakers. They have been in there 2 years now and still sound great.

 

When I bought my retro-radio from Biketronics, I ordered the speakers directly from Pez @ Hogtunes. I believe they were the 914 speakers. If I recollect, he told me that with this setup, the Sony 630UI, I'd have to use/order from the 1998-2005 series.

As of yet, I've had no problems out of either the Sony unit, the Hogtunes, or the Hog Pod tweeters. I plan to order the rear speakers from Hogtunes soon.

Hope this helps...
