please clarify yourself...

Will you ever do this for some of the heavy hitter amps?
ie.:

JL 400/4 or 600/6, Hertz HDP4, Alpine PDX, Arc Moto 600.4, ect

perhaps this winter.
I would need people to temporarily donate their amp(s).
my tests are on the bike as you can read in the test documents so it always takes some effort to get it all set up.

How would you compare the ST 4.1000D to the Rockford Fosgate PBR 300 X 4?


Thanks

Stay away from the ST they are way under powered The SS PN 1000D IS BeTTER THAN the ST for the soundstream.

EDITED, sorry did not see the ST.

ST series I had on the shelve for testing but did not even bother as the PA 4.2000D did not meet the specs on paper by far.
ST is probably worse than the PBR300x4.

general consensus here is the PBR300x4 is WAY UNDERPOWERED to achieve loud sound. hence I have not bench tested it. the PBR series in general are ubderspec;d meaning f.e. the PBR300x2 I started with on my bike was 150W RMS but birthsheet stated 192.
Nevertheless, the SS PN4.1000D or PA RZ4.3000D (OVERSPEC'D! is same amp as SS) is the way to go on a budget (150 bucks for an amp!). you will potentially lose FM reception, as stated over and over on this forum. and yes it will fit in the batwing

Thanks for the info AAWAV and Babyboy. Now to stuff it inside a Road Glide fairing

Thanks for doing these tests, writing up and sharing the results. They are very helpful.

FWIW, I noticed a slight difference between the BT4180's test document and collated summary page (1st post in this thread). The test doc states 160wpc and the summary page states 150wpc. If the correct value is 160wpc, then I am curious why the BT2180 tested less than the BT4180 if BT is using the same UcD boards for both amps.

HTH

keep in mind I was testing on Bike power. UN tested both amps as well with SOLID power supply (14.4V) and his test provided the spec'd numbers. as you can read in the test results, I was not able to test 2 ohm load, UN did.

Great information. Thank you.
