Amp help.

You could look into an Alpine PDX-F4 if you were looking to go the multi amp route. It's not that bad if you find a used one.

I love JBL too, they make some very high value products at a low price like the MS-62C's. I like the JL as well for it size and power. I am just looking around for the best value. Also if you run a/b amp to the front components vs a d amp does it make a difference in sound quality?

It used to. I personally can't hear the difference. The Class D full range amps today are all pretty good so you may not be able to hear the difference either. Obviously some are better than others. I just moved from an "SQ" A/B to a class D and I can't hear the difference. Granted it's a "good" one, but still. That JL is a good one. Even that little PPi is a good one. I wish they'd get off their ass and get that phantom 5 channel on the market already.

There will be purists that will swear to you that they can hear the difference between A/B and D. But the (arguably) best SQ car on the planet right now uses all class D amps.

I will keep that in mind, thanks.

Wait, you lost me. If I put 50 watts to them, I should be able to turn up the volume higher without them clipping or distorting.

I'm saying you would barely notice the difference between 50w and 75w.

[quote name='TaylorFade']Dude... not everybody is worried about "loud." Some people actually enjoy music. Not volume for volume's sake. Do you hae any idea how much power you're actually giving your highs? Even at "loud" levels? I think you'd be surprised.[/QUOTE]

@\-Josh\-; not if you dont know the clipping point of your head unit and amp.

I know, if ppi did have the 900.5 on the market I wouldn't be in this situation. So it is just based on preference, I follow. Personally, I prefer the D because it won't tax my electrical system as much. That is why I originally listed mostly d styled amps. One last thing about a sub, just so I can clear this up. If want a nice accurate, deep, and tight bass so I would go with a sealed enclosure?

Ok, thanks for clearing that up.

Sealed doesn't have the low end extension or efficiency of a ported box. If you have the room, I'd go ported. Especially with the lower power levels of those 5 channels. But as we've discussed already in this thread, you may not care about output.

Do you mean hitting the lower frequencies? You are correct I don't really care about the output levels in regards to loudness. I would match the sub based on the amp I pick. But with putting in a ported enclosure they take up to much space unless I were to go with something like one of JL's microsubs.

Also, do you know if that the JBL amp has a bass knob that you can buy for it? I can't seem to find one.

Bump for more opinions.

So I decided to go with the Alpine MRX-V70. Now I am looking for a sub for my system, out the ones I picked out, which do you think will best fit my application. The sub will be in a sealed enclosure.

Id look at a Dayton DVC 4ohm 10,or 12 for the price you would be buying a JL sub for, and they come with a 5yr warranty.Sound great in sealed enclosures,as well as ported,small spaceshttp://www.parts-express.com/pe/showdetl.cfm?partnumber=295-463,and will be great on that amp

Thanks for the recommendation, I actually really like that sub. Not to beat a dead horse though, what is the difference between a 10 inch and a 12 inch subwoofer?
