So Ive been building my new audio system over the past month, been slowwwwww but Im making headway. I got a old school kenwood deck , a 4 channel crunch powerzone amp powering 4 Polk audio db571 6x8s. annd that leads me to the next step: finding a good mono amp / sub combo to wire up next.

Any suggestion ? I was thinking a phonix gold class D amp with polk audio SR series 10" ? Also if anyone has come up with some good box designs for the ranger that could let you still uses the two jumpseats ? ( I got a 2000 supercab).

 

Phoenix Gold makes rather good equipment for the price from what I hear..
That looks like a great sub, but its hard to tell because I can't find any specs on it.
If you can get me the T/S numbers I can model it to give you an idea of what to expect from it. I can tell you its optimum size box so that you can judge if you have the space for your custom box. there also might be better lower priced alternatives.

Is your truck 4 door ext or 2 door ext? Its very difficult trying to build a system so that it does not interfere with the jump seats, many people end up sacrificing a seat for more options.

What model amp are you looking at? whats its power ratings? I should be able to tell you how loud it will get off of the power you put into it also.

 

i had a polk subwoofer. It was a great sub, and I wouldnt mind having it back!

 

I was thinking of this sub: Polk Audio MM1040DVC - Sonic Electronix so I need a good mono class D amp that can push out around 300 watts rms @ 4 ohms. Maybe: http://cgi.ebay.com/ebaymotors/CRUNC...QitemZ36031786

How good is crunch for a mono amp ?

Yeah if you can let me know the optimized airspace for the box that would be awesome !. Im going to be attempting for the first time building my own sub box so any help would be much appriciated so my sub doesnt sound like ****..lol Its a 4 door, I might just have to sacrifice a jumpseat so I can get a nice setup for my amps and the sub.

 

Well I tried going from the vague specs polk has on their site but they must not be accurate or something winISD doesn't like them. so you will just have to go by the boxes they have suggested. Here Polk Audio - Car & Marine Audio Speakers. looks like you want to shoot for a sealed box between 1.0 - .66 cf who knows what would be optimal without the specs...
Its pretty dumb that they do not give you the displacement of the motor structure, its pretty important to know how much the sub takes away from the final volume of the box.

I would say PG is of better quality then the crunch. really you can get away with almost any amp that puts out plenty of power. its best to exceed the RMS power rating for the sub. that way you can be sure your amp wont get "winded" and clip the signal. subs aren't sensitive to having clean power as mids and highs are.

 

Seriously, send a message to csb_electronics on ebay if you want polk stuff awesomely cheap, even if its not listed just ask if he has it or can list it, I got my db571's from him as well as my remote start alarm, i think the speakers were like 60 bucks shipped if I can remember.

B T Dubbs, polks website is not arranged that well to easily navigate, but the specs and TS parameters can be found hizzur.

get a rockford fosgate 10 inch slim box p3L sub i just got one and it fits perfectly between my jump seats. almost as if it was built to fit I STRONGLY SUGGEST GOING WITH THIS, and them put your amp under your jumpseat
