here are my amp choices. wich one?

None of those amps are what you want

They might be in your price range but there not doing anywhere near the power the rated look at things like this when you buy a amp rms wattage at the impedance desired.Next most 1500 watt amps will have 4 40 amp fuses the reason is Because 1500/12= 125 amps this is the amount of current the amp pulls any fuse size below this will blow.Are your subs dual 4 or dual 2 If there dual 2 you need a two ohm stable 1500 watt amp if there there dual 4 you need a 1 ohm stable 1500 watt amp.If I had l7s and they were dual 4s and I was on a budget I would get a power bass 1500.1 if I had dual 2s your very limited on the amps that will produce 1500 watts at 2 ohms the only one that comes to mind is a kicker zx 1500 which is pricey.But in the end remember you pay for what you get those amps that your looking at will probably be a mistake and they'll fail then you will have to buy another so why not just spend the money the first time.

 

never mind you need 1200 rms

But the amps I recommended are still good for what You need I thought it said l7s not l5s

 

I have an older PA that I'm pretty happy with.The Lanzar,I'd stay away from that.The Opti line is ok from Lanzar,but that's about it.I would pass on the Boss.Did you notice that the PA is a refurb?What ohm load are you trying to achieve?This is a decent amp:

i have a lanzar like that and its awful lol

 

if anything i like the 3rd one, but meh their all junk why you going so cheap?

 

I had this same conversation about that amp your looking at 6 monthes ago

my buddy has two kicker cvx twelves in a audi he bought the pa 1500 the amp broke two weeks after he bought it he had to pay to send it to episons pa and they sent it back and he sold it on craigslist. He bought a hifonics brutus bxi2008 it still works he's happy even though I'm not a hifonics fan.

 

i know a kid with the 5500 model. it works just fine for him.

i was told a long time ago." buy the best you can afford". if thats what you can afford then so be it.

even after impedance rise and voltage issues ( make sure you can supply the amp with sufficient current) you shouls still have more than enough power for your subs.

BUT.... do you have your wiring in order? big amps need current. do you have a good batt under the hood? you may need another batt in the rear close to the amp.

do you have a wiring large enough for a large amp like that?

 

well the batt in the trunk helps you to keep your power and ground runs short.

have you done the Big 3? maybe another run of power from the alt to the batt can help if you have voltage issues after installing the amp. you may be able to wir in another batt with no problems.

i have a stock 105 amp alt in my truck and 2 kinetik batts in the back. so, 3 batts on one small alt. zero voltage issues. it's over kill i know, but it don't hurt to have a lil extra amperage when needed.

 

no. i do not go thru lots of batts. i don't listen to my system at full blast long enough to discharge them.

if you were here in tampa,Fl i could show you this batt place that sells C&D batts dirt cheap. a lot of my teammates get their batts from there. 40 to 70 each for 134 ah batts.
