So you should put a fuse coming off of the front batt, then another fuse right before the batt bank and then another fuse between the batt bank to the amp? So 3 fuses total? Most people put a 300A fuse at either the front, back, or both sides but most people pick one or the other. I'll be fusing it closer to the rear battery.

Moneys tight but I really am contemplating putting an XS D3400 in the trunk because the 3100 would really strain my alternator

Either way. I just need to know which Size isolator I need if I do wire it in parallel but I was planning on just in the vehicle hooked to the amp.

I plan on running it with the car off sometimes (like when waiting for someone w/ the volume down). Isnt it also possible to just ground the 2nd battery and run the power wire to the monoblock?

Thanks for the tip. What size isolator would you use?

How would you wire the isolator?

I currently have an XS D1200 under the hood and a stock 150 amp alternator. I plan on adding a 2nd battery to power ONLY the 2500w monoblock and leave the first battery to run the 4 channel. I plan on adding an Optima yellow top 31T or XS D3100 (very little difference). What would be the best way to wire the battery?

with those speakers you won't notice a difference between classes I figured as much. I'll stay with the A/B for the better specs and damping factor anD lower price. Thanks for the info

It's not cheap but I found it cheaper. RE Audio (US Amps) IMO has a lot of clarity in they're amps. Both amps arenormally $300 but I found it for $88 on eBay new so it's fitting my budget more lol. I'm running Kicker KS65.2 components

You just answered my question considering I'm a huge audiophile haha. The A/B is alot cheaper anyway so that makes a huge difference.

They're both made by the same company, RE Audio. I just didn't know if there was a difference in the quality. The specs are a little bit better on the Class A/B but the Digital Class D is more compact, as it can fit under a car seat.

Im looking either at a full range digital class D amplifier with 80% efficiency or a class A/B with a 70% efficiency. Neither have much of a current draw towards my electrical but I just wanted to know how much of an actual difference in current draw there was.

The SX's are amazing sounding subs but the XXX honestly sold me. The SX's do have some issues with staying together which is why I didn't buy 2 SX 12s. I do like that whether it's dirty or clean, they take it clean all day.

Aren't they just custom pillars and gauges?

Looking to get a XS d3100 for my trunk setup. Willing to pay for shipping as well. Will accept as long as it's in good condition.

You would be the first I have heard say that the XXX subs rip apart at the leads

damn dude. Didnt have to punch RE in the nuts for that one. How was I disrespecting RE? haha.

I already have an RE XTX5000.1 which runs 2500w RMS @1ohm and I've came down to my final decision on a setup. I want to achieve great sound quality while still getting a respectable SPL level. I have came down to either 2 10" DC XL's or 1 12" RE XXX. I have heard the amazing sound quality from a XXX on 2000w pushing about 132db but personally I've never heard any systems with 2 XL 10's. Anyone have an opinion on which one to go with? I'm going to be throwing this in a Ford Fusion.

Right now, it's looking between US Amps xtx5000.1 or the sundown saz2500

Nice

I didn't know there were different XXX's lol. I was getting the new model XXX's

I was looking at the Hifonics BRZ- 2400 on it but I honestly think the sundown saz2500 would sound better overall.

I would use the DD just by looking at it but the problem is my cars PCM controls limit my car from running over 12v. Little ole 2008 Ford Fusion :/

Looking to run a XXX 12" in the trunk (2000w RMS). I had my eye on the hifonics Brutus, but i have been hearing split opinions. Any suggestions?

I was gonna run either setup on the DC 3.5k amp. After reading all the comments though I'm gonna side on DC. I'm not big into JL, they sound alright but I've heard better subs, Fi is more boom with no SQ in my opinion.
