AMP: You get what you pay for?

[kilimats]

I am confused, need a little help

I recently replaced my old amp JBL BP150.1 Mono Channel with a cheap $70 FLI Audio FL1200M-F2 (apparently a reputable brand in Europe). The spec on that new amp is 3x more than my old one yet the subwoofer bass output decreased just a bit, how could that be? should i not trust product spec anymore and only focus on brand like Alpine/JL/JVC/etc... and pay 3x more $$$ ?

I thought maybe the new amp had a bad ground but i tried connecting it to the battery ground directly with no improvement. The gain and bass boost knobs were set to max.

Here is a recap of the specs for the old/new amp and sub i use

NEW AMP: FLI FL1200M-F2
RMS Power Rating:
4 ohms: 400 watts x 1 chan.
2 ohms: 600 watts x 1 chan.


OLD AMP:

4 ohms: 75 watts x 1 chan.
2 ohms: 150 watts x 1 chan.
manual: http://www.jbl.com/resources/Brands/...nual/bp_om.pdf



FLI Audio Frequency 10 (FF10-F4)
10" Single 4 Ohm Frequency Series Subwoofer
Power Handling:
Peak: 1000 watts
RMS: 300 watts
Minimum input: 150 watts

CEA-2006 compliant, nuff said.

CEA has a list of standards that require the amplifier, wiring, speakers, headunits, etc. to meet certain standards in order to advertise that it does X, Y, and/or Z.

The JBL amplifier, and most large name brands are CEA compliant. Knowing it's CEA compliant means you know the power it's advertising to produce, it does produce.

Besides that, make sure the amplifier is tuned correctly, and if nothing else in the audio system has changed, then you can probably contribute it to the amplifier.

Not to mention seeing a singular 40A fuse on a class A/B amp that supposedly produces 600 RMS tells me it doesn't even come close to the 600W RMS.

For the most part you ALWAYS get what you pay for in one way or another.

^ thanks for clarifying, didnt kno about this standard.

I'll resale this POS amp and get an Alpine Monoblock 500 Watt RMS MRX-M50 instead, more money but worth it i'm sure

It all depends on the quality of amp like for instance I own a j2 jl 500.1 amp and if I bought the XD or hd version the bass response would be way more clear with less distortion but the same out put that's what happening you downgraded amps its not that anything is wrong it just has to with the quality of the amp. That's all

amp looks like it can only fit 8 maybe 4 gauge wiring for ground &power
