March 23rd, 2011 02:53 PM #1Hi Guys,
I need help in choosing an amp to power my seps. Currently i'm using Morel Maximo 6.5". A friend of mine is talking me into using the Firland FA360.4 amp to power up my seps. He says it's a 90 x 4 rms and it's more clean sounding compared to the JBL amps. My question is the Firland FA360.4 a reputable and good amp? In what league or level is the Firland? Need your inputs. Thanks.

Firland is a good entry budget amplifier. The next "level" would probably be Powerbass ASA600.4 or if you need more power, the RE 1600XT.

A good audio system start with the head unit signal through the amplifier and a set of speakers. It is very important to match each set to finally fine tune your system. The issue is in between the set of a good speakers and an amp to power the signal from the head unit, we have to over power these sets to finally eliminate the noise other than music, any amp that has the ability to stand at 100watts rms * 4ohm in 14.4volts (real power) can easily drive the speaker 90watts rms * 4ohm, the morel maximo is 90watts rms * 4ohm so we need an amp that has these specs, let say the power bass ASA 600.4x 4 ch Amplifier, it is a AB amp so we do not have the problem in signal, only in the power supply, you will be needed a at least 2 farad capacitor to maintain your voltage even in the long run, the total harmonic distortion of these amp is probably 0.05%, very low so the signal is purely accurate and audible to our ears, the frequency response of morel maximo is 50-20,000 hz and the powerbass is 20-22,000hz, so again we don't have any problem with it in frequency tuning, sensitivity will again meet there, maximo is 90.5db and the powerbass is 94db, CAUTION: do not bridge any speaker if your more on sound quality, bridging may cause the impedance of the speaker possibly lower than its own and may cause these speaker to distort.
Any amplifier that has these ability and suit your budget will probably drive your components, point to a good installer for that and you will enjoy its performance.. good luck sir.

I remember that 2x loudness is 10x wattage. So: 100w -> you want this to be twice as loud -> you'll need 1000W. Don't pay too much attention to wattage, just try to match them up. Focus on the quality of the amplifiers instead.
The additional 25W would give you "headroom" for future upgrades. You don't want to be powering your components too low, clipping occurs and damage occurs :P
Still, 80% from the RMS is a good rule of thumb as a power reference. The Morels is like Hertz. They're powerhogs unlike Focals which touts its high efficiency.
Does the Firland have enough power to power your Morels? Yes. Just keep the volume at bay. Would I recommend the jump to the Powerbass? Yes.
Although I'd have to disagree with Tsikotshop's comment about bridging. I'm a big fan of bridging due to the flexibility of 4-channel amps. Is there an impact on sound quality? Very minor, personally, can't really hear any of them :P The biggest perk of 4-channel amps? Running your speakers from passive to active.
