That amp is worthless for 3 reasons. 1. Its a Pyle. 2. Its a Pyle (yes its so bad its gets to be two reasons). 3. Not C.E.A. 2006 compliant and no actual ratings posted. 1000 what? Watts, Rubber Bands, ninjas? Is that Peak? RMS?
That head unit is junk. Its a box that plays cds and radio. All other functions such as bluetooth, nav, hd radio, ect require addons. Not worth 410 for a dvd player either, can get a Jensen with better options and bigger screen for same amount. Yes i see its on sale for 300, still not worth it. I paid $120 (on sale) for a Dual, with BT, HD radio, A2DP BT streaming, Ipod control ect. Dual xhd7714, at best buy. I like it. Read a lot of good reviews on it. HD radio is awesome, but you have to be able to get good signal. So its kinda spotty, but could be multitude of reasons on top of i live in the way far out suburbs. total with 4 year warranty and installation components needed was about $200 even.
MY GOD, those subs suck. First off if you have a sub capable of pulling 3500 watts peak, you need an amp capable of pushing over 4000 watts peak. Other wise buy several amps so you don't have to wait when you blow one to change it out. Secondly, since there not C.E.A. 2006 compliant, don't believe a single word of the 1000 watt rms ratting. How was it rated? Was it sunny with a slight breeze, 72 degrees F in a 92 Honda Civic Hatchback with a ported box, down wind of a cattle farm on stall mucking day? Or was it a Saturday evening, 45 degrees out in a convertible, during a tornado, with the top down? No im not trying to be funny. There is a reason for this standard. Heres a link i suggest reading up on it. Brochure For C.E.A. Standard
If you don't have say $1500 to through away at good (not great just good) equipment, ie head unit, speakers, sub amp ect, don't bother upgrading. A sub, amp, box, and wiring kit should be about 500 (low) to 750 (decent). Mind you for that your getting a single 10" maybe 12" single possible dual voice coil sub, rated for 500 watts or less, a single box, on amp enough to run the one sub, and the wires to connect it to a after market stereo and power and ground. Nothing else.
What i suggest you do before even looking at equipment is decide on a couple things first.
1. How much will you spend. Anything less then 1500 and you should not even be considering anything with a dvd player in it. Unless you dont mind cheap ones that skip and jump and work horribly. You get what you pay for in this industry. The bigger the price the more features and better quality it usually is.
2. How do you want it to sound. You worried about buying a sub, and a box, and a head unit, but have considered what you want the sound to be like. Do you want Quality? Loud? Both? What kind of music do you listen too? Certain sub sizes and setup are better for different types of music..
3. Cargo room? Is it an issue? if so smaller gear may be a better option. Maintaining certain factory components. Factory fit? will that speaker be to deep and now doesn't fit in that spot.
4. What was the the factory system. Do you have an infinity system? Do you intend to keep the original speakers if you dont? Upgrades for the system?
Thats just 4 of many factors you need to decide on before you even consider which gear to buy let alone how much each part is worth. The shop i worked at often made about 2500 or more for a standard head unit, 4 speakers (one component set) amp, sub, sub amp, custom box and wiring. This was good equipment. Nothing special, played cds, maybe burned ones, was tuned and sounded decent. sub picked the low end up and overall it sounded great. My own person vehicle at that time, had over 10k in equipment in it. I competed in both spl and sql. Big difference in hitting 145 decibels and sounding great or doing both. Big difference in cost too.
Also please dont read this and get scared of upgrading your system. Im not trying to scare you, just trying to educate you on some finer points. Good equipment is not sold at a off name website with no tech support. Try crutchfield. Yeah you will pay more. But the free tech suport, often free install goodies, and awesome customer service will make your day that much better. Plus they do have deals here and there. I bought a complete Infinity Reference speaker upgrade from my 99 WJ with infinity system. Some of the speakers were blown. Bought all three sets (tweets, 6x9, 6 1/2) for less then 300 shipped with install gear, tech support and next day shipping.
Just some food for thought.
