Aiwa CDCZ137
2 Power Acoustic Built N Crossover Tweeters
2 6-1/2"Alpine SPS-170A
2 12"RockfordFosgate Punch HE2 Woofers (RFP4212)
RockfordFosgate Punch 801S Amplifier
Subzone h-122 enclosure
knukoncept Wiring
Dynamat Trunk Kit
-----------------------
thats what i have!! in a 67 ford mustang!

okay i have those 2 12" he2's there 4ohm DVC 400wattRMS 800wattMAX EACH connected to a 2 channel 801s rockford amp im running each sub to each channel which its 2 channels and 2 subs. okay would that be perfect?

Okay and the wiring is knukoncept, okay the 0 gauge is gonna be fused by the battery with a 300amp fuse and fuse holder, im running 0 gauge to my trunk cuts off at a distro block , then from the distro im runnin an 8 gauge to the amplifier, and using pair of twisted shielded rca's i think there knu koncept too, is that good wiring way i did it?

subzone box h-122 is made up of 3/4in of MDF , its 1.4cubic ft each chamber and its for 2 12" woofers, so would them he2's be good for this box?

and the trunk has dynamat and its an old car !!

wat do you think about this system think it sounds or would sound good!!????
or wat are your oppinions on this or what?
thanks!!!

If it sounds good to you, then you should be happy with it. If you are asking if you should you switch anything out, then that's a completely different story. My friend had an Aiwa head unit, and he ended up taking it out because CD's were always skipping. As for your power wiring, are you upgrading to more powerful amplifiers? If not, then 0 gauge is overkill, and the 300 amp fuse won't really protect anything.

Don't like rockford subs? Then don't look at my car =)

Get rid of those Power Acoustik tweeters also.

You need to amplify your fullrange speakers. That AIWA deck has no internal crossovers; so, on top of being underpowered, they will be reproducing low frequencies. You will probably get decent volume out of the front if you just add a amplifier to those Alpines. I assume you are going for loud and not for sound quality? Get a cheap 2 or 4 channel amp. If you get a cheap 2 run the alpines off it. I did not even try to look up the tweeters, post the specs. If the tweets are decent, get a 4 channel and run them and the alpines off it. Sounds like you have the bass side more then covered. When you get an amp, cross the 6.5's over at 80-120hz, depends on the crossover slope, power your giving then, listening tastes, other factors. Cross the tweeters over as high as the highpass will go (most will only go to around 250hz or so). If you dont get an amp your going to have crappy highs/mids and lots of bass. Hurray... If I were you I would buy better fullrange speakers, if you have not bought yours already.

Matter of fact if you have not bought the stuff already, id get different equipment entirely...

UMM Okay thanks for the replies!!!

okay so should i just get a 4 gauge kit for that rockford fosgate 801s amplifier??!!!!?

i know this aiwa deck sucks but it hasnt skipped alot!!! and these alpines and tweeters sound crisp and loud and good sound quality im serious!! but i bet if i run them off another amp itd cramp them up more the cheapest amp thats pretty small i have is a 444watt sony exploded amp lol maybe if i hook that up with the alpines and tweeters? and the bass would that sound good? well or wat can i do for them alpines to sound even louder i guess ill leave the tweeters on the deck !

1) Seriously get rid of the extra tweeters. You should only have one pair of tweeters on any given channel.

2) Put bass blockers on your Alpines.

These two changes will greatly increase the sound quality for next to no cost.

If you want to take the next step do this:
3) Put the best quality 6.5" components you can afford in kick panels. Buy a decent quality amplifier to drive them.

You should be fine for the bass as long as the box is anywhere near close to the right size. Remember to get professional help setting the gains or do sufficient research to do it yourself. It isn't a volume control. Set the sub amps low pass crossover at 80 or 100hz.

No, I have to disagree... There is NO SUCH THING as too much power wire, (Point of diminishing returns? POSSIBLY. But too much? NEVER) and YES the 300 amp fuse will protect. It will protect exactly what is SUPPOSED to protect - the car! If the power cable's insulation is compromised in ANY way, the fuse will blow, and not burn the car to the ground. The 300 amp fuse he has installed is not SUPPOSED to protect the amps...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I would get rid of the whole setup to be honest ... I really don't like it and i don't think it will sound good. May I suggest the following: (1) Keep the Optima, great batter (2) Lose the AIWA, uprade to Alpine or Pioneer (3) Destroy the Power Acoustik tweeters and replace with Boston's, a/d/s, or even fosgate's new ones are good (4) Lose the alpine 6.5'' and replace with either a cadence CVL-6K, Nakamichi SP-S6500, or CDT EF-61's. Those will sound great. (5) Lose the HE series subs, they suck (sorry to be blunt). The HX2's are a lot better woofer and far more durable and i think they are fosgates best subs (excluding the TEAM FOSGATES). (6) Change the amplifier according to your woofers. Stick with company's like alpine, cadence, us amps, mmats, or even stick with fosgate (some of the new ones ain't bad) (7) Change the enclosure to whatever subs you get, subzone makes a decent enclosure. (8) Wire is wire, so keep it. (9) Keep the dynamat, that is always good. This is a real system and it will sound great. You should spend less than $1500 if you do it all on ebay and it is all good stuff. Good luck

yeah i know thaat would be great but that is all i can afford and i want it to sound good just with few adjustments like kfr01 said thats all i can spend on a system right now maybe laters ill upgrade a lil but this is all i can put

Sorry haemphyst, I was speaking about the power wire as if he didn't have it already. Yes you can never have too much, but if he hasn't already bought it, he should just get 4 gauge and save the extra money for better equipment.

As for the 300 amp fuse, I know it will save the car, but I always aim for the amplifiers fuses, and nothing more. I didn't mean for it to say that it wouldn't protect anything at all (the amplifiers were the main thing on my mind when I wrote that).

okay so im thinkin of gettin a 4 gauge kit and puttin bass blockers or an amp on them alpines!! that should do it huh?

The way you are hooking up the subs are fine. To my knowledge the RFP4212 is dual 2ohm subs. So your basically running 2ohm stereo which is more than sufficient.

Yes I would run 4 guage back to the amp.

I've done alot of systems on a budget. If you like the tweeters keep them. Its your car and your taste of music. If you like the crisp highs then its your discretion to keep or remove the tweeters.

As far as the Alpines, I would either add a small amp w/crossover or just use a bass blocker. You should be able to find them at your local stereo shop.

I would amplify those alpines, something like this https://www.cardomain.com/item/LITLA13002 or https://www.cardomain.com/item/JENPS475. Something like that. If your not going to put anything but deck power to them, your not doing them justice.

Wow, is everyone clueless and lost in the dark? - uthinkuknoaudio

maaudio1 thanks for replyin and for ur opinions but them woofers are 4ohm each

so there 4 ohm subs! ???

so if i buy some bass blockers on them alpines i should be set and with that 4 gauge kit??

"maaudio1 thanks for replyin and for ur opinions but them woofers are 4ohm each

Noooo..... These are your subs https://www.cardomain.com/sku/ROCRFP4212. Dual 4 ohm voice coils.

IMO "bassblockers" are a waste of money if you are using the deck power, you have little to gain. https://www.cardomain.com/shoplist~b~Lightning+Audio~t~Passive+Crossover+Components So like 12-15 $ A waste of money for little to no audible change. If you havd 3.5's or 4x6's 4's i may change my mind. Just get a amplifier if you want better sound.

Okay so their dual 4ohm. Wire the subs in series to create an 8ohm load on each sub, then parallel the two subs together for a single 4ohm load. That way you get a 4ohm mono load

And I disagree and agree with the whole bass blocker complex. If you have the money get an amp w/ builtin crossover for the Alpines. However, if you are on a srict budget the bass blockers will work. Most bass blockers crossover at 150hz only allowing notes 150hz and above to be heard from the Alpines. Basically midbass and treble.

Agreed. An amp with an electronic crossover would be best. Bass blockers are the cheap solution. Just know that SOME SORT of crossover should be put on those speakers if you like to push those drivers.

well well . maudio this is how i have my subs wired !

im wiring each sub to each channel which its 2 subs and 2 channels!

its 2 12"RockfordFosgate Punch HE2 Woofers (RFP4212)400wattrms 800wattmax 4ohm each!

then the amp is RockfordFosgate Punch 801S Amplifier 2 channel!! so im gonna wire it like this go here https://www.rockfordfosgate.com/rftech/wiringwizard.asp?WoofQty=1+woofer&WoofImp=Dual+Voice+Coil+-+4+ohms+x+2&image.x=16&image.y=14 its Wiring Option #1 im gonna run each sub in a 2ohm load to each channel on that amp !! that should work perfect right!! instead of having to bridge same thing??

-------------

Yes, use option 1.

Well i think this system could have some serious changes for the better even on a low budget..However if it sounds good to you, keep it.

SO was i wiring this right??

audio bass how can i make it better at low budget??

-------------

Yes option one will work. 2ohm stereo is basically how your wiring it. The amp will run more sufficient and stay cooler that way.

Side note (MA Audio - not the user) sucks. A lot better company's out there for the same money or less ... I'd buy fosgate anyday over it (Was that random? If so sorry!)
