I bought a 3523 from him. Works great and made me a great deal. Good guy here.

10-26-2011, 05:34 PM
I will see if i can google them up and post them..May take me a few min.All working as they should,have scratches and so forth due to age,not perfect,but still look fair,and presentable as well..Thank you sir^^^^^..ItsAJeepThing,and am estatic to hear that the amp met your expectations as well..3523..It was,and is one of my favorites!

10-26-2011, 06:50 PM
Well,I did some searching..Thanks to the google sites..As follows at 11.6/12v:
3522- 2x30@4ohms
1x80@4ohms bridged THD.3%-100Db
1x80@4ohms bridged THD.3%-100Db-pretty much same as the 3522
Now this is a little B/A amp that ItsAJeepThing picked up from me
1x100@4ohms bridged THD.3%-110db
1x70@4ohms bridged THD.4%-105 db
KEEP IN MIND:these ratings are at the 12v specs,so your car now is usually at 13.4 up to 14v,so the wattage will be MORE! I know that the 3522 will push 2 sets of 6x9,and a pair of 150 rms 10s pretty decent as well as the 3540,the 3513s-I know it will push a pair of 6.5 -50rms speakers,5.25,2)sets of 50rms tweeters,and I put it on a 150rms 8in sub at one time,Now the 3523-Hmm-Now that amp has got some real power, i had it on a pair of kicker KS 6.5 and a pair of KS 25 tweeters,and a pair of 360rms ABC Audiobahn 3ways,and a pair of 1oorms Infinity tweeters,I have had it on a 600rms sub,2 150rms 10s,4 200rms 8s,2 sets of JBL GTQ 100rms 6x9 before.I wouldnt be,and i have as you have been told? to run these amps for front stage,or rear staging,and even a single 12/10 ect.Good amps,and fairly clean.I will test again before they go out to make certain they are working properly for you.I just have too many amps,and they really need to be used rather than sitting up.They were all around $120 and to like $190 for the 3523 in like 92,and still working great.If you need fresh pics let me know,and I will get them. I will place some here in a bit.Thanks,and hope this info helps out.Pm me ,or let me know here,I will be checking time to time...thanks:thankyou:

26528135265281372652813626528123Here are some fresh Pics..I have the plugs for all except the speaker plug for the 3513s,and Power plug,and speaker plug for one 3522.I will keep looking for them..If I cannot find them,I can make something for them,or you can buy on e-bay,but will be tested before shipped.Thanks..A little dust here and there,some scratches/nicks,but presentable..
Trades??/Trades n cash??? Can use some 12g wiring and possibly 8ga kit???Thanks:escape:

The 3540,I picked up on E-bay a few weeks back with intentions of putting it in my nephews scion in the kick panels,but we went with the 4ch JBL GTQ 200 instead,but I ran it for a solid week on my rear Audiobahn ABC 6002 seperates,200rms(100ea.), and sounded great!!
