Or buy an amp that has RCA output. Old skool style!

Or get a processor!

Seas is supposedly more musical. But JLW3v3 isn't a slouch either. I suspect the Seas can go lower. The JL should be an overall performer. If you can get the original JL then imho it's a better buy. But Seas is probably a more SQ sub.

I don't think the Helix A2 can power the JL properly. Is it 1 or 2ohm stable? If yes then ok otherwise it won't work.

All the 3 amps you suggested are pretty good. I don't think you'll really be able to hear the difference between the three if compared side by side.

If it's Mike you're getting it from, then I suggest you ask Mike for the best combination for your application. He knows his stuff!

And you're right about the Helix, better to over power the sub than to underpower it. At least that way you'll have some headroom.

Personally I'd go for the dual mono and the JLW3v3! HEhehe.. different people different tastes.

The dual mono is a underrated amp. It outputs way more than it claims. The Helix A2 is a safe bet too if you're not confident.

The Genesis Dual mono has plenty of character. Sound wise I think it's quite unique. Can't really explain it and with that sort of power it'll have no problems with almost any speaker.

The Helix A2 is also a monster of an amp, but it's very clinical, very german - plain and simple sounding. It's very detailed, but lacks character. I used this to drive my Dynaudio tweeters in the past and it was bloody fantastic. Worked really well with my Dynaudio Mids too. So it really depends on how you match the fella (A2).

Both amps are pretty good but the A2 is way larger in size (though the Genesis isn't that much smaller). Personally - since both amps are going to be used to drive a sub, I'd be pretty hard pressed to hear the musical difference between the two for a sub. Components is a different story.

Tru Hammer H1!

Actually I disagree to some extent too.

Passives can be tweaked quite a bit to change the characteristics of the speakers. A high end silver SQ cap, a Bybee quantum filter, batcap, mundorf resisters, etc all changes the characteristics of the sound.

So you probably can tweak your passives but a different kind of tweak. You don't fiddle with crossover points and all (even though you can) and instead fiddle with the quality of the frequency (?)

Technically you should be pulling the wire from your HU / crossover to the door.

No mah.. he said "pull wire from dashboard to door". Technically that's not right. Dashboard not part of the ICE maaahh.

I know someone selling this amp at RM800 nego. TriC @ Chew from icehifi

Good seller, great condition amp

The JL12W0 (I assume is v3) is SVC 4ohm 300w RMS.

The 4075 bridged is 4ohm 220w slightly underrated. It shouldn't be a problem powering this sub but you won't be maximizing the sub but doesn't really matter. So yes, it'll work.

Running the sub by itself rather than on a multichannel amp just stresses the amp less and those SQ audiophiles will claim that it 'sounds better'. I honestly can't tell the difference but no harm taxing the amp less.

xforged : Uh.. do I know you? How'd you know my name? Anyway I had a PHD 2200, not the 4075.

Cheras/KL I can only think of 2 shops : EA Autoworks and Etoni.
PJ I can think of more : CV Audio, Audio Creations and a few others I haven't had interaction with.

Attach ground to the car body and see

9855 is the last of the last generation of Alpines which were known to be bright sounding. I personally like the 9855 over the 9887 which is a little more refined and you could say pioneer-ish. Both have their pros and cons. I personally choose the 9855.

Recently changed my 9855 to this :



and I'm in loooooooooooooooooooooooooooooove

DSP? Not needed as it has 2 RCA out. The tube version of this player is a little too warm for my liking and this is brilliantly bright and crisp. Just nice for my type of music.

Correct, no TA, no EQ etc. The crossover for my components is my custom passives, the sub goes through the amp. But sub and amp isn't mine so I'm not touching those.

And ignore Howie's RM100 comment. It's a private joke between the crazy bugger and me.
