Strengths:
Everything

Weaknesses:
None.

Summary:
This has got to be the best amp ever!!! What I don't understand is how everyone is buying all these high wattage amps and spending crazy amounts of money on multiple amp setups with no quality. I have this amp driving a $550 set of mb quart 6 1/2" speakers in the front with good quality Clarion tweets. In the rear I have Pioneer 6 1/2" 3-way. For bass I have a high quality Viper 10" subwoofer that pounds. Bridged at 2ohms stereo. Definetley best, most versatile, impressive, not enough to say about amp I've ever tried!!!

Strengths:
everything

Weaknesses:
speaker and wire terminals, they could be a lot bigger

Summary:
i've had this amp running, every kind of speaker and or subwoofer you can think of from 2' tweeters to 15' mmats juggernaughts, or ground zero's for over ten years. there is no amp out there this versitile, very very underated. they retail for around 450.00 which is crazy but i've seen them on ebay really cheap. this amp is like fine wine it gets better with age. do not buy if you want your nieghbors running for cover, buy if you want tight, clean, crisp sounding music. sure my son will put in hibbity wibbity music and i think its gonna blow my taillights out, but i explain to him its all about clairity, not constant booming loudness, thats what the monoblocks are for.

Strengths:
power, ease of conversion from old amp, easy to understand directions, technical support team, NO NEON OR UNNEEDED LIGHTS. I praise ADS for remembering that this is a amp and not a toy!

Weaknesses:
a bit pricey

Summary:
I have a very old Ph-15 that this amp replaced. So the Bar was already set pretty high. This amp not only reached the bar but it surpassed it. very quiet, just the right amount of power(I listen to mostly Jazz), perfect size.

Price Paid:  $350.00 from SoundCity

Strengths:
Many strengths: - very quiet operation - very clean power - extensive crossover system - very versatile - the best sounding amp I've ever used

Weaknesses:
I don't care much for the adapters that I had to attach my wires to; it can be hard to fit decent gauge wires in there.

Summary:
This is definately the best and most versitile amp I have ever installed or used! a/d/s/ provides crystal clear power- don't let the low ratings fool you! A bit pricey but worth every penny. I ran an a/d/s/ 5.25" component set with the first 4 channels (1 channel per speaker) and the last 2 channels were driving 2 2ohm 10" Kicker XPLs. Everything ran perfectly without the amp ever overheating or any audible distortion at all.

Strengths:
Audio Clarity and lack of noise

Weaknesses:
instructions were not the best.
No dealer in my area

Summary:
Using it with two sets of 344is (have loved/used a/d/s since early 80's - remember 320i's and P100 power plates?) and a pair of fosgate mid bases (pretty lame speakers).

This is probably the quietest amp I've ever had. Absolutely NO hiss or rumble at "0" volume level, no engine noise, no thump when powering up either (which seems to be a problem for some). It's just amazingly clear.

The output is just about perfect for the 344is's and overdrives the fosgates a bit.

Crossover setup is sweet as it is extremely tuneable to match the components being driven.

Don't know how much reserve power it would have for larger subs - would be my only reservation with the amp.
