What is the difference and advantage of one over the other?
I'm looking at this one
ED
Driver Name : e10Kx.44 /x .14
Voice Coils : Dual 2 or 4 ohm
Power Range : 150/400 watts
Applications : Sealed / Vented
Price - $75.00

any recomendations for a reasonably priced amp to go with it?

 

the only advantage of a DVC sub is that you have more wiring options to achieve a more desired impedence load.

i suggest a JBL80.2 which will put out 160 watts at 4 ohm so you could go with the dual 2 ohm model wired in series

 

I'd suggest a mono sub amp like the JBL BP300.1, and the dual 4 ohm coil sub. The mono sub amp is stable when running a 2 ohm load (which is what parallelling the 2 4 ohm coils gets you), and the lower impedance allows the amp to produce more power. Overall, the 300.1 with the 2 ohm impedance will put out almost double the power of the 80.1 running a bridged 4 ohm impedance.

 

ya but his sub is only rated at 150 rms

 

Why the 80.2 and not the 150.1? Are the JBL amps generally rated pretty close to what they are making? Also if it is 75w @ 4 ohms, and 150w @ 2 ohms, does it follow that it would be 300w @ 1 ohm?

Also, I think its up to 400 wrms, b/c eD recommends the avionix 400.2 amp, which brigded is 400 wrms.

 

i just suggested that based on the RMS rating...im not too familiar with ED products lately.

i suggested the 80.2 over the 150.1 because if you want to upgrade in the future the 80.2 is a 2 channel rather than a mono so you could use it to power your speakers.

 

wouldn't the sub be grossly underpowered if it only had 80w to the sub? Would that cause a problem? I would definately like to have the option to wire up my 6 x 9's but my first concern is the sub.
The JBL 180.2 seems like a good fit.
Do all these amps have the "power switching supply that far reduces pull on the vehicle's electrical system"?

I'm wondering why the 180.2 is cheaper than the 300.1...

 

so? My subs were rated at around that and had no problem taking my Kicker ZR600 at full power.

A little more power is ALWAYS better than a little less.

 

Not to mention as well that a one channel amp is usually a D-class amp. A D-class amp is actually better at amplifying low freq then the other normally seen class AB amp.

So that 150RMS will be put to much more efficient use in this case.

:lala:

 

I wouldn't call it better. It requires less power to operate, which saves you a little money on wiring, and its disadvantages are such that they typically aren't audible in the bass frequencies.

 

I agree with Jim, a class D is more effiecient, not actually 'better per se'...a Class A/B will suffice just as well powering subs....500 watts is 500 watts...no matter what class the amp.

 

Yes, a class AB amp will do just as well powering subs as a class D. However, the point I was aiming for was that a class D amp will not work as hard in doing so as it is a more efficient amp and will use power more efficiently.

I would imagine it would run cooler, and provide a nicer signal when demands of quick power bursts are asked of it.

Please don't think that just because I say one thing is better than another that I am indicating the lesser product is no good at all. I am simply trying to provide a comparison just like everyone else.

 

i suppose it would be alright if you ran it in a sealed box, or with a subsonic if you were running ported. From what i hear those EDs can take a beating so it should workout.
I just think that car audio is such an addictive hobby he might want to upgrade soon and with the 180.2 he can switch that to a frontstage amp with a larger sub amp
