I just “finished” a very long installation in my CT200h. Full 3 way front system + rear fill. It sounds pretty good before tuning for the most part, but this is my first helix system, and I’m not sure how much of this I’m doing right.

Inputs (tapped from factory amp outputs):
A: Front Left
B: Front Right
C: Mid Left
D: Mid Right
E: Woofer
F: Not connected

Available inputs (from the two factory amp connectors):
Pin 3 = FL+
Pin 8 = FL−
Pin 10 = FR+
Pin 9 = FR−
Pin 4 = RL+
Pin 11 = RL−
Pin 5 = RR+
Pin 12 = RR−

Pin 1 = WF1+
Pin 2 = WF2+
Pin 3 = ML+
Pin 9 = ML−
Pin 4 = MR+
Pin 10 = MR−
Pin 8 = Center+
Pin 7 = Center−

Problem number 1: I know this isn’t tuned (and I’m not really sure what I’m listening for since this my first big audio project), but it sounds a little “off”. I’m assuming the input signal is too weak, because that’s what it’s warning me to, but I tried my head unit at 50/62 for that and it may be clipping (i don’t have a scope). Any louder and I’m worried I’ll clip dsp input.

Problem number 2: because the input is so weak, my amps have to be turned almost all the way up to max on gain and still don’t clip. All speakers handle it pretty well, but I’m once again worried about damage even though there’s no clipping to my knowledge.

System is as follows:
Peerless NE19VTS-04 tweeters
FaitalPro 3FE22 midranges
Dayton RS180P-4 woofers
2x CA30 Fosi audio amplifiers

From Jiffy.com’s website: “We do not charge restocking fees, however shipping fees (if any) will not be refunded” and “We issue a free return shipping label on the first return per order.”

I ordered 9 Next Level T-Shirts in various sizes to find the closest size to take to my tailor for fitted athletic tees.

I ended up returning the whole order in preparation to reorder 10+ shirts in my size, however they processed my refund at $16 less than what I paid on a $88 order. I cannot find any information on why they shorted me the total amount, and contacting them is literally 100% impossible. I tried the AI bot on the website and emails across various subreddits. All of their emails are down. No phone number, etc.

Returns policy states first return is free and I got free shipping on the order so it shouldn’t have been taken out for return shipping.

Im not particularly interested in placing my next $200-300 order with them if they are this hard to work with, so if anyone else has a better place to buy Next Level shirts that would also be great.

If anyone else has had any luck contacting them or has any more information that would be great.
