Such a Good Review, I Won't Bother Writing Mine! (Reply to this comment)
by nick1326
WOW- I thought I was the only one who cared so much about my sound and reviews!! What a great job- and you hit the nail right on the head with the 500/5, because although the JL's tend to be power-hungry little beasts, the class-seperation feature on the multi-channel JL makes it very stock-alternator compatible!
The only complaint I had about the 500/5 is that (like all JL amps) they have lots of punch, but can be a bit lacking in overall sound quality. My a/d/s/ PQ's are much warmer, making the front mid-bass drivers smoother and more linear- they tend to be able to get more low-entension without stress and therefore the lower- mid bass from the front makes for a warmer sound and better front presence.
Nevertheless, if it weren't for my commuter car dying (and making a couple of nice a/d/s/ PQs available for other cars, my Bimmer just may have gotten a JL instead of an a/d/s/ for price reasons!
You've written a phenomenal review of the amp. Great job- nice work on your system.

Great review and system! (Reply to this comment)

Since you are focused on a good front stage (a wise choice, IMHO), I dare to suggest you to run your system actively, the midbass units powered by the 100W channels and the tweeters by the 25W channels. More power means more headroom and even better sound. You could run the rear speakers right from the deck's amp. Congratulations on your setup and nice review.

Congratulations on your choices and general system architecture. It is never too much to put the emphasis on system design; the more you study it, the better it sounds.
I am also running a five channel amp (Genesis Five Channel, made in England) in my system and an Alpine deck (CDA-9813R). Since your amp has different front and rear power ratings (a great feature IMHO) I dare to suggest you to run your system actively, i.e., power the midbass with the 100W pair and the tweeters with the 25W pair. This is only possible if either the speaker crossover has the bi-amp feature (two pairs of inputs) or the amp has a bandpass (HP and LP) filter for the front channels. Otherwise you will be feeding the midbass with unnecessary high frequencies that will just heat up the voice coil. Another necessary feature to run your system actively is the amp's capability to drive the four channels with just the front inputs, otherwise you will miss the fader possibility.
I have my system running this way (although both front and rear channels have the same power) and it sounds wonderful, lots of clean power and dynamics. This configuration also allows to change the crossover point between the midbass and the tweeter (only if you use the amp's variable crossovers), which sometimes can improve the soundstage. The rear speakers can be powered by the deck's internal amp, which in the Alpine is rather powerful (for a deck amp, that is)!
But the only true judge is your ear: if it sounds great, just keep it like that!
