Help! anyone that knows about Audio Systems

[CplJasonB]

ok so im adding an audio system to my 08 Tahoe, i have bought 2 13w7 to go with 2 JL 1000 amps. i have 2sets of ZR650csi, each set has a 85watts continous power handling and a 255watts peak music power, my question is, what amp do i need to match these 2 sets!?!? btw, i want a JL amp since im going all JL.

 

[groundscr8pr]

get a 450/4.

 

[CplJasonB]

all i need is one 450/4? to power both sets(4door speakers and 4tweeters)?

85*4 = 340. 450w is >30% over the rated RMS value... that's quite a bit if you ask me.

Who sold this to you? Anyone reputable would have given you this info beforehand. IMO!!!
Unless of course you went E-bay or something.

Are you planning on putting both sets up front or putting one set up front and one in the rear? If you're going to do the latter, then the 450/4 will be perfect, but if you're trying to put both sets up front, It would be better to have 2 300/4's, 1 for each set; then you could run an active crossover network.

Also, Just my 2 cents, but you're going to need at least 500 more watts per sub for those 13's to sound at their best. Its a shame that JL only has a 1000 watt amp.

with proper gain setting and tuning it will be great. it will also help if your not a gorilla with the volume knob. but again with proper gain and x over settings a little more power wont be an issue.

damn, thanks alot guys for ur input. and yes im planning on putting one set in the front and the other in the second row, basically, im replacing everything. So i will be getting the 450/4 amp. And to groundscr8pr, i like been a gorilla at times lol, especially the first days after i have it install. and to gibson, should i get another 1000 amp for the 13w7's? the reason i have these 2 cause i been told thats all i need and if i go over 1000 for each sub, it voids the warranty.

 

[groundscr8pr]

a 1000/1 is fine for each sub. i have installed this combo with great results. are you doing vented or sealed boxs?

oh really, so ur the guy i need to talk then. im still thinking about the box, i dont know what would make it sound best, since i dont know anything about car systems, what do u recommend? also i have 2 optima red top(better than yellow i been told) 800cca batteries(is this enough? btw this is the highest cca i could find, here atleast...), im replacing the one the car has with this, and the other for the amps. im thinking about the H.O alternator, the guy at the audio shop said i dont need to upgrade the alternator... i dont know if he is right, but yea. btw ill put the pics up when everything is done lol thanks for the help

You'll be fine with your alternator. Do you want your subs to be louder (SPL) or a better quality(SQ)? SPL is higher vented, while SQ is better sealed

Better quality, so I guess I have to go sealed then. So I have all the parts =) I'm going with no H.O alternator. Will 2 red top batteries of 800cca do the job? Meaning one red top will be used for my tahoe and the other for the amps

 

[stevek]

Dude, you'll be fine with a yellow top(Better for this application) and your stock alternator. I ran two 12" L7's and a 300.4 and I could play for quite a while with the car OFF and did not worry about a dead battery.

Sorry for the late reply.

The 1000/1 will push the 13W7 just fine. I suggested adding another 500 watts per sub because for the short time period I had a 13W7, I was dissapointed with how it sounded(compared to my 1 10W7 on that same 1000 watts), but when I heard that same sub on a RF 2000.1bd it blew me away. Also, Whoever told you that any more than 1000 watts will void the warranty is misinformed, 1500 watts is the RMS rating(and that is under rated)

With the Battery situation, I'd go with a 1 yellow top as your second battery and leave your stock one alone. Your stock electrical system is fine for what you have( I have the same exact amps).

You can get good quality sound from a vented box, its all in the craftsmanship. I'd recommend a vented box for you because they are more power efficient(that 1000 watts will usually produce more sound than in a sealed enclosure) and, well you heard my spill on your power situation lol

 

[groundscr8pr]

i would recommend vented also. take advantage of increased efficiency. if you have enough money i would highly recommend a h.o. alternator. extra battery dont produce extra voltage. the only advantage to dual batts is key off run time. 2 1000/1 s and a 450/4 at high volume can easily draw 200 amps. factory alt usually is about 130.

So I have the system installed. But have a problem, when I put the volume up, my sub makes a popping noise on certain notes, does anybody knows what could be causing this?also after playing my system my Amps get really hot, is this normal?

I believe that popping you hear is called "clipping". Basically it's your sub's way of saying turn me down. Wikipedia has a good article on it I believe, go look it up if you're curious.

And yes, your amp can get hot after use, it's normal, no worries!

 

[CplJasonB]

I just don't get it. If that's the limit for the subs, how come I see these YouTube videos with people having the same exact setup, while there subs are pounding the car like if they want to come out the vehicle.
