lanzar vs Alpine Old School Class A/B giants fight it out on the dyno!

[@Randy_G]

I had an Opti500 back in the day when they first came out. Very impressive back then.

[@Hi-Fire-do]

I didn’t realize how good they were back then. I have an opti 160q. Bought it new. Was amazing. This amp in this video is really amazing. I’ve been using it for months in my truck. Thanks for watching.

Test the alpine 2 ohm bridged that's where u really see the power it can do.

[@Hi-Fire-do]

Yes, the 1505 is ok with 2 ohms bridged, it has a "low ohm" switch that is kinda hidden to protect the amp in 1ohm stereo or 2 Ohm bridged use. It really isn't rated or mentioned much in the owners manual in this mode. I will assume though that it internally limits it to keep it from melting down. My Soundstream amps have this function as well. I have a MRV 1005, its littler brother that doesn't like 2 ohms bridged and will go into protect when pushed hard in this same mode. the 1505 seems to be ok with 2 ohms bridged. Also the Bench was limited to about 100 amps of current, which likely limited the output. I'm upgrading the power supply from 50 to 75 amps at 13.6 volts, which should help (also using a full size battery). I now have to run a 25 amp 120v circuit so I don't burn my shop down!

Those alpine amps are extremely solid and sound amazing.

That lanzar is a beast i have that one and the 700x2. My 500x2 did over 1300 certified, its a current hog and from the mid or mid late 2000s Its a revamp of the original designs from the late 90s im told

[@Hi-Fire-do]

I believe that. I ran out of power or it would have done more. I was testing g it on 10 gauge power wire. Good think it was only 18”.

[@joshholden8561]

Alpine 3545 was the king of the big power class ab 2 channel rated 750 x1 @ 4 ohm I ran the amp bridged at 2 ohm load it did around 1500 RMS amp was from mid 90s had clip light on the amp dual power inputs used 3 30 amp fuses I ran it bridged at 2 ohm so I ran 3 50 amp fuses alpine 3545 also had dual fans this amp was one of the best high power class ab I've ever heard and saw making huge power I believe these also had .003 or .005 THD so the amp sounded amazing.

Lanzat was solid back in the day

[@Thumper68]

Man back in college I had a huge amp and I had to sell it and my L5s to pay rent but I can’t remember what the amp was and haven’t found a picture of it anywhere online with hours of searching and i can usually find anything. It was 32” long damn near as wide as my enclosure. It was supposedly 600x2 and it pushed those L5 hard. This was 2002. One day I’ll figure it out.

[@joshholden8561]

@@Thumper68 hey , profile had some really really long class ab amps back in the day check out the brand called Profile .

[@mr.18s73]
