Rushmore AMP BRACKET MODIFICATION FOR SOUNDSTREAM PN4-1000D
Just finished my amplifier install on my 14 limited using the stock amp bracket and wanted to share my mods so others do not have to use the OVER PRICED BRACKET FORM J&M
What I did was cut the bracket at the indicated areas and flatten out the areas were the amp was going to mount to get it low enough to clear the fairing.Then bent and reformed the area to get the pieces to realign for welding.If unable to weld I don't see why you couldn't cut and replace the front mounting areas and use angle brackets.Then secure with machine screws
The minimum clearance at the front of the amp is 1/2 of an inch for fairing clearance.
(When mocking up and final install input side of amp is on clutch side and speaker and power on throttle side)
Bracket after welded and repainted
When mounting amp to bracket I used #8 machine screws
When installing amp the wiring harness running along the back of the gauges has to be relocated above the amp so there is a minimum of 1 inch from front of amp bracket to amp
The side clearance measurments are shown in the pictures.
This is the final install picture

Great post man.
Thanks for putting up all the pics and details on how to get this ton. Lots of folks wanting to use this amp in the rushmores without having to get the expensive mount. Props for cracking the code.

That's odd as the part numbers for the RUSHMORE SGS/SG, ULTRA/LIMITED all show the same part number for that bracket

Rushmore bikes are a totally different animal than 13 and down bikes. A great easy solution is to get an amp tray from baddazz bikes for 50 and mounting will be real easy.

How does one order this amp tray? Been on their website and can't seem to find it...not the most user friendly site.

Best way is to call them. They are in Temple, TX 254-771-0009. Or if you are on Facebook look them up and send them a message. Good guys down there
